Summary
The Interactive Properties panel provides universal editing access to the properties of documents and objects in design editors. The panel dynamically determines its content based on the document or object that is currently selected and presents specific properties and settings that relate to that document/object.
Panel Access
The Properties panel is available in all editors and can be accessed in the following ways:
- Click the Panels button at the bottom right of the design space, then click Properties.
- Choosing View » Panels » Properties from the main menus.
- Double-click on an object in the design space.
- Using the F11 keyboard shortcut.
Schematic Support
When the active document is a schematic document (*.SchDoc
) and no design object is selected in the design space, the Properties panel presents the Document Options.
The following collapsible sections contain information about the options and controls available under the panel's General tab:
The options in this section of the panel determine which schematic objects may be selected in the design space.
- All - On button – select to remove object filtering so that all types of objects may be selected.
- Object buttons – toggle each object button to enable/disable the ability to select that object type.
The following collapsible section contains information about the options and controls available under the panel's Parameters tab:
When a design object is selected, the panel will present options specific to that object type. The following table lists the object types available for placement on a schematic sheet – click a link to access the properties page for that object.
Modifying Data Strings
The Properties panel has the ability to modify data strings using formulas in the Schematic Editor. Formulas and expressions offer a convenient method of modifying attribute parameters of multiple selected objects to change their location or string-based values such as the Designator and Comment. This allows you to apply a specific expression to the selected string objects. The expression can include any built-in arithmetic operators and functions that apply to strings (found in Pascal). If you want to use the current value for the attribute as part of the expression, you will need to make reference to this original value either by using the full name of the attribute or by using the exclamation character (the supported substitute for the name of the attribute currently being modified). When using attribute names, if any names contain spaces, these must be replaced by the underscore character. For example, use of the Component Designator field within a formula should be entered as Component_Designator
.
Using the Smart Edit Feature
Some parameter string fields also provide access to the Smart Edit dialog when multiple objects are selected, which is opened from the associated button.
The Properties panel offers further support for string modification through its Smart Edit feature. Select the cell entries pertaining to the attribute that you want to modify for all required objects, right-click then choose Smart Edit from the menu that appears. The Smart Edit dialog will open.
The dialog offers two methods for performing string modification accessed from the Batch Replace and Formula tabs.
Schematic Library Support
When the active document is a Schematic Library document (*.SchLib
), choose the Tools » Document Options command from the main menus – the Properties panel presents the Library Options. The following collapsible sections contain information about the options and controls available:
The options in this section of the panel determine which schematic library objects may be selected in the design space.
- All Objects button – select remove object filtering so that all types of objects may be selected.
- Object buttons – toggle each object button to enable/disable the ability to select that object type.
When a design object is selected, the panel will present options specific to that object type. The following table lists the object types available for placement within the library design space. Click a link to access the properties page for that object.
PCB Support
When the active document is a PCB document (*.PcbDoc
) and when no design object is currently selected in the design space, the Properties panel presents the Board mode. The following collapsible sections contain information about the options and controls available:
The options in this section of the panel determine which PCB objects may be selected in the design space.
- All On button – select to remove object filtering so that all types of objects may be selected.
- Object buttons – toggle each object button to enable/disable the ability to select that object type.
- Grids – used to toggle whether the cursor will snap to the active design space grid. When this option is enabled the cursor will pull, or snap, to the nearest snap grid location. The active snap grid is displayed on the Status bar, and in the PCB editor Heads Up display.
- Guides – used to toggle whether the cursor will snap to manually placed linear or point Snap Guides. A Snap Guide will override the Snap Grid.
- Axes – used to toggle whether the cursor will axially-align (in either the X or Y direction) to the enabled Objects for snapping. The Axis Snap Range defines the distance within which X or Y axial-alignment will occur. A dynamic alignment guide line is displayed when alignment is achieved, from the current cursor location to the axially-aligned object snap point (hotspot).
- Snapping – select directly or use the Shift+E shortcut to select whether you want to snap to objects on:
- All Layers – enable this option to allow the cursor to snap to any electrical object on any visible layer.
- Current Layer – enable this option to allow the cursor to only recognize and snap to objects placed on the currently selected layer.
- Off – enable this option to turn off snapping to hotspots.
- Objects for snapping
- On/Off – check to enable snapping for the desired objects.
- Objects – a list of the available objects.
- Snap Distance – when the cursor is within this distance from an enabled object snap point (and snapping is enabled for the active layer), the cursor will snap to that point.
- Axis Snap Range – when the cursor is axially-aligned and within this distance from an enabled object snap point (and the Axes feature is enabled), a dynamic guide line will display to indicate that alignment has been achieved.
- Board Size
- Horizontal/Vertical – the overall length of the board in the horizontal (X) and vertical (Y) directions.
- Area – the area of the board as defined by the board shape (the black region).
- Components Area – the sum total area occupied by all components on the board. Refer to the Component Area topic for details on how the component area is defined.
- Density – the percentage of the board Area occupied by the Components Area.
The automatically calculated Components Area is the area that highlights when you click to select the component. The selection area is determined from the geometries on the Courtyard layer, i.e. when that layer is not present, the combination of the geometries on the Silkscreen, 3D Body objects, and Copper layers (strings are excluded).
- Components/Layers/Nets/Primitives and Others – displays information for each listed category such as the total number of the listed item.
- Reports – click to open the Board Report dialog in which you can specify the content to be included when generating a detailed report for the board.
- Units – use to select the default measurement units for the current PCB document. Default units are used to display any distance-related information on screen or in reports. The default units are always used if a unit's suffix (mm or mil) is not entered when specifying any distance-related information.
- Polygon Naming Scheme – select a naming system from the drop-down menu. There are four choices of naming templates:
NET NAME_LXX_PXXX
LXX_NET NAME_PXXX
NET NAME_LAYER NAME_PXXX
LAYER NAME_NET NAME_PXXX
where:
NET NAME
– name of the net to which the polygon is connected. If the polygon is not connected to a net, the name NONET
is used.
LAYER NAME
– user-defined name of that layer from the Layer Stack.
LXX
– system assigned copper layer number based on the current order of layers in the Layer Stack where Top Layer is L01
. This value is updated whenever the order of copper layers is changed.
PXXX
– system-assigned numerical index; unique for each polygon on the board.
Design changes, such as moving a layer in the layer stack, renaming a net, or changing the naming scheme will result in automatic name changing. Affected design rules are automatically updated.
- Designator Display – use this field to determine how designators are to be displayed. It can be difficult positioning the designator strings in a multi-channel design, as they can end up being quite long. As well as choosing a naming option that results in a short name, another option is to display just the original, logical component designation instead. For example,
C30_CIN1
would display as C30
. This would of course necessitate some other notation being added to the board to indicate the separate channels, such as a box being drawn around each channel on the component overlay. The following options are available:
Physical
– choose to display the physical designators. These are the designators displayed on the compiled tab views of the schematic source documents. For multi-channel designs, designator format is determined by the Designator Format field on the Multi-Channel tab of the Project Options dialog. Physical designators are unique, e.g., R1_CH1
.
Logical
– choose to display the logical designators. These are the designators displayed on the Editor tab views of the schematic source documents. Logical designators are not unique; for example, the R1_CH1
physical designator will become simply R1
.
- Sheet Settings – use this region to configure the PCB sheet, the color and visibility of which are configured in the System Colors section of the View Configuration panel.
- X/Y – enter the X and Y coordinates for the bottom left corner of the sheet. This distance is measured from the absolute origin, which is the bottom left corner of the design space. The distance can be defined in either metric or imperial units regardless of the default units (which are determined by the Units setting). To specify the units when entering a size, add the mm or mil suffix to the value.
- Width – enter a width for the sheet here. The sheet provides an area that emulates the traditional drawing sheet and is useful for placing information such as dimensions, notes and title blocks. Information placed on mechanical layers can be linked to the sheet so that they only display when the sheet is being displayed. Sheet size can be defined in either metric or imperial units regardless of the default units (which are determined by the Units setting). To specify the units when entering a size, add the mm or mil suffix to the value.
- Height – enter a height for the sheet here. The sheet provides an area that emulates the traditional drawing sheet and is useful for placing information such as dimensions, notes and title blocks. Information placed on mechanical layers can be linked to the sheet so that they only display when the sheet is being displayed. Sheet size can be defined in either metric or imperial units regardless of the default units (which are determined by the Units setting). To specify the units when entering a size, add the mm or mil suffix to the value.
- Get Size From Sheet Layer – with this option enabled, the sheet background is automatically calculated from the bounding rectangle of the set of objects placed on the Sheet mechanical layer. With this option disabled, the options above become available to define the sheet area manually.
When a design object is selected, the panel will present options specific to that object type. The following table lists the object types available for placement within a PCB document – click a link to access the properties page for that object.
Although
Tracks and
Lines are actually the same object, the difference is how the software behaves during their placement, which is why there are different commands.
After launching the Place » Line command, the cursor will change to a cross-hair and the editor will enter line placement mode. Placement is made by performing the following actions:
- Click to define the starting position of the line.
- Move the cursor to set the length and angle the line then click again to complete placement.
- Continue placing further lines, or right-click or press Esc to exit the placement mode.

This mode is typically useful at the end stage of board layout when the ultimate level of fine-tuning is required (for example, when manually dragging tracks, cleaning pad entries, etc.).
- Weak – in this mode, a low level of glossing is applied with the Interactive Router considering only those tracks directly connected to or in the area of the tracks that you are currently routing (or tracks/vias being dragged). This mode of glossing is typically useful for fine-tuning track layout or when dealing with critical traces.
- Strong – in this mode, a high level of glossing is applied with the Interactive Router looking for shortest paths, smoothing out tracks, etc. This mode of glossing is typically useful in the early stages of the layout process when the aim is to get a good amount of the board routed quickly.
- Automatically Terminate Routing – when enabled, when you complete a route to the target pad, the routing tool does not continue in routing mode from the target pad but rather resets and is ready for you to click on the next source pad from which to route. If this option is disabled, after you route to the target pad, the tool will remain in routing mode and use the previous target pad as the source for the next route.
- Automatically Remove Loops – enable to automatically remove any redundant loops that are created during manual routing. This allows you to re-route a connection without having to manually remove redundant tracks. However, there are times when you need to route nets, such as power nets and when you need loops; you can toggle this option for a selected net by using the Shift+D shortcut to override this global setting for the same net.

Layer Stack Support
When the active document is a Layer Stack document (*.PcbDoc [Stackup]
), the Properties panel presents options pertinent to that layer stack depending on the chosen tab (located at the bottom of the Layer Stack). Tabs include Stackup, Impedance, Via Types, Back Drills, and Printed Electronics Stackup. The following collapsible sections contain information about the options and controls available for the various Layer Stack tabs:
The Stackup tab allows you to edit the layer properties of the Layer Stack.
The Layer Stack Manager mode of the Properties panel: an overlay layer, an inner layer, a dielectric layer, and a plane layer.
- Name – the name of the layer.
- Manufacturer – the layer manufacturer.
- Material – the layer material. This can be pre-defined in the Altium Material Library dialog (Tools » Material Library) in the Constructions field, or user-defined in the Layer Stack. Click to open the Select Material dialog to choose the desired material for the currently selected layer in the layer stack.
- Thickness – the thickness of the signal layer.
- Dk – this is the Dielectric Constant (also referred to as εr in electromagnetics). This indicates the relative permittivity of an insulator material, which refers to its ability to store electrical energy in an electric field. For insulating purposes, a material with lower dielectric constant is better and in RF applications, a higher dielectric constant may be desirable. In addition, the lower the relative dielectric constant, the closer the performance of the material to that of air. This property is critical to matching the impedance requirements of certain transmission lines.
- Df – this is the Dissipation Factor. This indicates the efficiency of insulating material by showing the rate of energy loss for a certain mode of oscillation, such as mechanical, electrical, or electromechanical oscillation. In other words, this is the property of a material that describes how much of the energy transmitted is absorbed by the material. The greater the loss tangent, the larger the energy absorption into the material. This property directly impacts the signal attenuation at high speeds.
- Process – displays the copper plating process that is applied to the base copper that makes up the outer signal layers of the PCB (the Top Layer and Bottom Layer).
- Weight – the weight of the copper per unit area, usually expressed in ounces/square foot (e.g., 0.5 oz/ft2).
- Orientation – this defines which way the components point (orient) on that layer. For the top and bottom sides, this is set automatically in a new board. For other signal layers, it is used for:
- Rigid-flex designs, where components mount on an inner signal layer that becomes a surface layer on a flex section, the software needs to know which way those components point. Use the drop-down to select the required orientation. Choices include: Not allowed, Top, and Bottom.
- For a design that includes embedded components, the software needs to know which way a component points. Refer to the Designing a PCB with Embedded Components page for information regarding setting the component orientation in the layer stack. Use the drop-down to select the required orientation. Choices include: Not allowed, Top, and Bottom.
- Copper Orientation – this defines the direction that the copper is laminated onto the core. Use the drop-down to select Above or Below, which determines the direction from which it is etched.
The
Copper Orientation can also be chosen using the drop-down in the
Copper Orientation column of the
Layer Stack. To enable the column, right-click in the header, choose
Select columns then enable the
Copper Orientation entry in the
Select columns dialog. Also, the
Trace Inverted option in the
Impedance Profile mode of the panel can be used to configure the copper orientation.
The orientation can be configured using the Copper Orientation drop-down in the Stackup mode of the Properties panel in the Copper Orientation column (if it is currently displayed), or by the Trace Inverted checkbox in the Impedance Profile mode of the Properties panel.
- Pullback Distance – the distance from the plane edge to the board edge.
- Frequency – this is the frequency at which the material is tested and the value that Dk / Df correspond to a certain frequency. Frequency is also taken from material references.

- Resin – displays the resin percentage of the layer.
Notes on Constructions and Resin:
The choice of laminate construction can significantly impact both cost and performance. As should be expected, a single-ply construction will typically represent a cost savings compared to a multiple-ply construction. The magnitude of this savings will depend on the specific glass styles involved and a host of other parameters. Performance can also be affected and should be considered when specifying the constructions to be used. First, single-ply constructions are often lower in resin content. The other main benefit of single-ply constructions is dielectric thickness control, beyond resin content considerations. Tighter thickness tolerances can be achieved using a single-ply construction.
Constructions with relatively lower resin contents are often preferred since they result in less z-axis expansion and can therefore improve reliability in many applications. In addition, lower resin contents can also improve dimensional stability, resistance to warpage, and dielectric thickness control. On the other hand, constructions with higher resin contents result in lower dielectric constant values, which are sometimes preferred for electrical performance. In addition, a certain minimum resin content is required to ensure adequate resin-to-glass wet-out and to prevent voids from occurring within the laminate. The ability to wet out the glass filaments fully with resin is also important for CAP resistance.
- Material Frequency – this is the frequency at which the material is tested and the value that Dk / Df correspond to a certain frequency. Frequency is also taken from material references.
- GlassTransTemp – this is the Glass Transition Temperature (also known as TG) and is the temperature at which the resin changes from a glass-like state to an amorphous state changing its mechanical behavior, i.e. expansion rate.
- Note – enter any pertinent notes for the layer.
- Comment – enter any necessary comments for the layer.
- Stack Symmetry – enable to add layers in matching pairs, centered around the mid-dielectric layer. When enabled, the layer stack is immediately checked for symmetry around the central dielectric layer. If any pair of layers that are equidistant from the central dielectric reference layer are not identical, the Stack is not symmetric dialog opens.
When Stack Symmetry is enabled:
– An edit action applied to a layer property is automatically applied to the symmetrical partner layer.
– Adding layers will automatically add matching symmetrical partner layers.
- Library Compliance – when enabled, for each layer that has been selected from the Material Library, the current layer properties are checked against the values of that material definition in the library.

The Substack region will only be available if the Rigid/Flex option is enabled in the Features drop-down.
- Stack Name – enter the substack name. Naming the substack is useful when the X/Y stackup region is being assigned a layer substack.
- Is Flex – enable if the substack is flex.

- Roughness Factor – characterizes the expected maximal increase in conductor losses due to the roughness effect. Enter a value between 1 to 100, default is 2.
Use the Impedance tab to configure the Impedance Profile requirements. The required Impedance Profile can then be selected in the Routing Width or Differential Pairs Routing design rules.
- Impedance Profile
- Description – enter a meaningful description. This field is optional and will be displayed wherever the Impedance Profile name is displayed.
- Type – use the drop-down to choose the impedance type. Choices are Single, Differential, Single-Coplanar, and Differential-Coplanar.
When working with coplanar structured impedances and the standard single/differential impedances, values for each variable are automatically calculated based on the user-defined Target Impedance and Target Tolerance, and the physical properties of the board layers. These automatically calculated values can be adjusted by entering new values into the edit boxes of the Layer Stack Manager mode of the Properties panel.
- Target Impedance – enter the impedance you want to achieve.
- Target Tolerance – enter the tolerance you want to achieve. You should consult with the fabricator to find a realistic value for tolerance that the fabricator can deliver.
- Transmission Line
- Trace inverted – enable this option to invert the trace, as demonstrated in the Properties panel. This option is the same as the Copper Orientation option displayed when the Stackup tab is active and defines the direction that the copper is laminated onto the core. The copper orientation defines the direction the copper projects away from that substrate. You can also think of it as the direction the copper is etched from, either above or below.
- Etch – the Etch Factor is
= T/[(W1-W2)/2]
, which reduces the total cross-section area of the trace by the thickness of the copper squared. Consult the board fabricator for information about the Etch created by their processes.
To exclude the Etch from the calculations (i.e. assume there is no slope created along the trace edge), set the value to 0.
- Width (W1) / (W2) – W1 is the width of the trace you route, W2 is the width of the upper surface of that trace once it has been etched, with the Etch factor applied. There is a forward/reverse calculation feature available for trace width. The default is for the width to be calculated based on the Target Impedance you entered (forward calculation). That width may be a value that the fabricator may not be able to deliver, such as 5.978, and they will want a more sensible value, such as 6.0. You can enter 6.0 into the Width field and press Enter on the keyboard to recalculate the calculated values (Impedance, Deviation, etc.). The button turns gray (becomes inactive) and you are now in reverse calculation mode. If you click the button to make it active, you are again in forward mode and the Width (W1) will revert to the calculated value. This feature lets you explore realistic fabricate-able width options. Manually entering a value for W2 will update the etch factor to suit.
- Impedance – the software calculates the impedance based on the properties of the materials used to make the board (copper, core and prepreg), and the cross-sectional area of the trace (determined by the width, thickness and etch factor of the trace).
- Deviation – this is a measure of the difference between what you wanted (target impedance) and what you got (calculated impedance). The software calculates the impedance deviation (what you will actually get based on the material and dimensions entered) based on the properties of the materials used to make the board (copper, core and prepreg), and the cross-sectional area of the trace (determined by the width, thickness and etch factor of the trace).
- Delay – this is the amount of time it takes for the signal to travel from the sender to the receiver.

The Library Migrator's associated Properties panel settings provide advanced control over the migration configuration for the selected library (or sub-library group). The panel's option settings are defined by the default system settings or those specified by the applied Component Template. The settings are user-editable, allowing you to change the migration process as required, and may be restored with the Reset to Default link (top right).
The panel's General tab sections are as follows:
- General:
- Component Type – The type of component detected by the migrator for the selected library, and by association, the template that is applied (see Component Template below). Overrule this setting by editing the field, which will create a new component type, or by selecting an alternative type using the drop-down menu options (or via the button) – this is another way to address an uncategorized component issue. Choose the
[LibraryName]
option to set the type to be the name of the selected library.
- Component Template – The Workspace-based Component Template that will be applied to the migrated components, and by association, their Component Type setting. Overrule this setting by selecting an alternative template using the drop-down menu options (or via the button). Set this option to
[Create new]
for the automatic creation of a template derived from the source library parameters and the Library Migrator's current settings, or choose [No Template
] to prevent a template from being applied or created.
Note that the Component Type and Component Template settings are effectively bound together when set to an available Type/Template – for example, if either is set to Capacitors
the other is automatically set to Capacitors
. However, if in this case the Component Template setting is changed to [Create New]
, another Capacitors
template (named with an appropriate version/revision suffix) will be created to comply with the current settings. Existing Component Templates are not altered by the migration process.
- Parameter Mapping – The parameter matching between the library parameters and those in the applied component template (or the default settings where no template is available), and also the type of value for each parameter (Text or a unit-aware type). Use the Source Library Parameter column drop-down menu options to change the mapping, and the Type column menu options to overrule the existing setting determined by the template or defaults. Choose the
<Skip>
option to not include a parameter. Any parameter that has not automatically been matched to a source library parameter (is set to <Skip>
by the system) can be manually mapped to a suitable Template parameter – for example, the source parameter ROHS
might be selected to match the RoHS Compliant
parameter defined by the Workspace template. Parameter names can be edited, and Parameter sets can be added, edited and removed. The base component parameters (ID
, Name
, Description
) may be remapped, but are otherwise read-only.
For the Workspace Parameter ID
, the Source Library Parameter is set to <Auto>
. This results in component IDs automatically created based on the Naming Template specified in the panel's Component section, found under the panel's Advanced tab. The ID mapping can be changed to use any parameter in the source library (that is unique for each component entry) by choosing an alternative from the Source Library Parameter drop-down menu. Note that the base component parameters (ID
, Name
, Description
) may be remapped, but are otherwise read-only.
- Part Choice Mapping – The list of manufacturer part or supplier link parameters recognized by the migrator, which will be used to derive Part Choices entries for migrated components. Use the drop-down menu options to redefined the mapping, or add and delete mapping sets. Note that by default, manufacturer part and supplier link parameters are not included (are skipped) in the migration process. Where multiple supplier links are included with a library component, the primary supplier reference (
Supplier 1
/ Supplier Part Number 1
) is used for the Part Choices field entries.
- Migration Checks – View or set the migrator's error/warning response to violations of the migration validation rules. Use the Report Mode drop-down menu to change the response and icon for a Violation Type entry. Note that if the
Fatal Error
report mode is selected, it will block the migration process when this violation is detected.
The panel's Advanced tab offers settings for all migrated data object items, as set by the system defaults or the applied Component Template. These includes Component, Symbol, Footprint, and any created Component Templates. The settings for each migration object include:
- Folder – The target Workspace folder for the migrated object, which may be manually edited (e.g., to create a new target folder) or selected via the browse button ().
- Naming Scheme – The object's Workspace naming specification as defined by the Component Template, or in the absence of an active template, the scheme set for the target folder (or as manually entered). Use the drop-down menu to choose from the available Naming Schemes. Note that a change in target folder path (Folder) may be accompanied by a change in the applied Naming Scheme, as set by the folder itself or by an applied/associated Component Template.
- Revision Naming Scheme – The naming arrangement used for the object's Workspace revisions, as set by the applied template or selected from the entry's drop-down menu options. Only those schemes enabled by the system will be available as an option.
- Lifecycle Definition – The Lifecycle system that is used for the object, as set by the applied template or selected from the entry's drop-down menu options. Only those definitions enabled by the system will be available as an option.
The Component object section includes the settings for Duplicates Detection to avoid duplicate components from being created in the target Workspace.
Constraints Manager Support
- Switch to Dialog View – after launching the command, the view mode will change from Document View to Dialog View, which opens the PCB Rules and Constraints Editor dialog.
- Units – use to select the measurement unit as desired.
- Select – when enabled, the filtered objects will be selected in the design space.
- Zoom – when enabled (default), the filtered objects will be zoomed and centered (where possible) in the design space. Use the Zoom Level button to adjust the zoom factor that will be used to zoom in on filtered objects.
- Normal/Mask/Dim drop-down – provides options for visibly contrasting filtered and unfiltered objects within the design space.
- Normal – filtered objects are visible in the design space and the appearance of unfiltered objects remains unchanged.
- Mask – filtered objects are highlighted in the design space with all other objects made monochrome.
- Dim – filtered objects are highlighted in the design space with all other objects retaining their colors but shaded.
- Scope – lists all the scopes that have been defined.
- Query – displays the queries defined for the associated scope.
- Import – use to import the selected scope to the Constraints Editor. This option is only available and accessible if a scope is selected in the dialog that is not already in the Constraints Editor.
- Export – use to export the selected scope to the Constraints Editor.
- Edit Library – use to open the Scopes Library dialog, where you may store query-based object matching scopes. custom scopes can be imported, managed and exported for reuse in other custom constraint rules.
