  • Y - the y-coordinate (where applicable) specified in the workspace that the guide is to pass through or point is to be located at.

A coordinate can be defined by clicking on the relevant field then entering the value. Alternatively, and where applicable/available, click  to the right of the field then specify the required point directly in the PCB workspace.

• Color - click to open a drop-down to set/change the color of the associated guide.

• Add - click to add a new snap guide or snap point. Choose the corresponding command for the required guide type from the associated menu; an entry for the new guide/point will be added to the grid. The following guide types are available:
  • Add Horizontal Guide - use this command to add a horizontal guideline at the desired Y-coordinate location in the workspace.
  • Add Vertical Guide - use this command to add a vertical guideline at the desired X-coordinate location in the workspace.
  • Add +45 Guide - use this command to add a 45 degree (y=x) guideline that passes through the desired X,Y coordinate location in the workspace.
  • Add -45 Guide - use this command to add a -45 degree (y=-x) guideline that passes through the desired X,Y coordinate location in the workspace.
  • Add Snap Point - use this command to add a point snap guide. This is a hotspot that you manually mark within the confines of the default snap grid. During an interactive process such as placing or moving an object, that objects' hotspot will 'snap' to a point snap guide when it passes into close proximity with it.
• Place - click to place a guide. Select the guide type from the drop-down:
  • Place Horizontal Guide - use this command to place a horizontal guideline at the desired Y-coordinate location in the workspace.

  • Place Snap Point -  use this command to place a point snap guide. This is a hotspot that you manually mark within the confines of the default snap grid. During an interactive process such as placing or moving an object, that objects' hotspot will 'snap' to a point snap guide when it passes into close proximity with it.
• - click to delete the currently selected guide.

• 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 dropdown 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.

• 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.
  • 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 workspace. 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 - eEnter 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 - enable this option to size the sheet from the sheet layer.

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 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.
• Remove Net Antennas - enable this option to remove any track or arc end that is not connected to any other primitive and forms an antenna.
• Allow Via Pushing - check this option to allow pushing a Via when in Push Obstacles or HugNPush Obstacles mode.

• Net Name - name of the net that the accordion is part of. Displays the * character if multiple accordions are currently selected.

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 (left image), an inner layer (middle image), and a dielectric layer (right image).

• 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 an 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 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 orientation can be configured using the Copper Orientation dropdown in the Stackup mode of the Prop panel, in the Copper Orientation column (if it is currently displayed), or by the Trace Inverted checkbox in the Impedance Profile mode of the Prop panel.

    When Stack Symmetry is enabled:
    - An edit action applied to a layer property is automatically applied to the symmetrical partner-layer.

• Width (W1)/ (W2)- 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 will probably be a value that the fabricator will 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 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 will revert to the calculated value. This feature lets you explore realistic fabricatable width options.

The list includes templates found in the location specified in the Data Management - Templates page of the Preferences dialog. Note that a default schematic sheet to be used for new multi-board documents may be defined in the System - New Document Defaults page of the Preferences dialog.
  • Template – use the drop-down menu to select from a list of standardized page templates, and if required, use the  button to refresh the template and drawing.
  • Width/Height – the dimensions of the current page size shown in the current document units (see the General section above).
  • Source – use the browse button () to navigate to and select an alternative template source in the schematic *.SchDot format.
• Standard mode – set the sheet size to a standard page format.
  • Sheet Size – use the drop-down menu to select from a list of standard page dimensions.
  • Width/Height – the dimensions of the current page size in the current document units.
• Custom mode – set the sheet size to specified custom dimensions.
  • Width – enter the required sheet width measurement.
  • Height – enter the required sheet height measurement.

Margin and Zones

Defines the size of the sheet border graphics and its zone divisions. Uncheck the Show Zones box to hide the zone divisions in the border graphics.

• Vertical – set the number of divisions (rows) in the vertical sheet margin. The alpha-numeric zone labeling type is defined by the Origin and Letter Position settings.
• Horizontal – set the number of divisions (columns) in the horizontal sheet margin.
• Origin – sets which corner of the document sheet(s) the perimeter zone alpha-numeric indicators will begin from (zone position A-1 or 1-A).
• Letter Position – set where the letter zone indicators are placed on the document sheet, either in the horizontal perimeter zones (columns) or the vertical zones (rows).
• Margins – set the distance (in the current units) between the page edge and each of the four border lines as indicated by the arrows associated with each entry field.

• Dash Pattern – the line/spacing definitions for the dashed Line options in units of 0.02mm (when in metric mode). For example, a pattern Value of 20,10,20 defines a repeating 0.4mm, 0.2mm, and 0.4mm dash arrangement with a cycle length of 1mm (50 units in total). A custom dashed line option can be created through the button and removed with the button. Use the button to restore the default entries and their values.
• Line Thickness – the weight or thickness of the available Line style options. A custom line thickness option can be created through the button and removed with the button. Use the button to restore the default entries and their values.

The Properties panel Parameters tab lists all available User and System parameter Name/Value pairs available in the current project document.

• Parameter Name and Value columns – lists the available parameters grouped by type, where User and System parameters are indicated by their associated icons.
  • User parameters () – parameters included in the document sheet template or those manually added through the panel. Both the Name and Value of User parameters can be edited directly in the list.
  • System parameters () – parameters included in the applied project template or those added through the Parameters tab of the Project Options dialog (Project » Project Options). System parameters cannot be edited through the Properties panel list.
• List filter options – select the icon to enable/disable Project level parameters in the list. Select the icon to enable/disable System parameters in the list.
• Add button () – select to add a new User parameter to the Parameters list. Use the button to remove a selected User parameter from the list.

• Production Quantity - the number of boards to be built. It is important to define this field as this is used during supply chain searching to check component availability from the suppliers.
• Currency - the preferred currency to display component prices. Exchange rates for currency conversion are refreshed daily provided you are signed in to your Altium account. When you disconnect from Altium (on the System - Account Management  page of the Preferences dialog), access to these updated rates is lost. In this situation, there is an option in the BOM reports dialog to use cached data.
• Price Per Board / Order Price grid - Price per Board is the sum of the prices of each individual item detailed in the BOM Items grid; the Order Price grid is this value times the Production Quantity. If target prices have been defined for each BOM Item, the Target column reflects these. To enter a target price for each BOM Item, enable the TargetPrice column on the Columns tab of the panel, then enter the price of each item in the Item grid.

Supply Chain information is presented in the lower region of the ActiveBOM interface, showing a manufacturer component on the left with one or more colored supplier tiles to the right of it. This region displays data when valid supply chain information can be identified for a BOM Item. Each of these Manufacturer & Supplier(s) Details rows is referred to as a Solution. The manufacturer details are abbreviated to MPNs (Manufacturer Part Numbers) and the supplier details are abbreviated to SPNs (Supplier Part Numbers).

• Solutions per Item - the number of manufacturer parts you would like to be located for each BOM Item.
• Suppliers per Solution - the number of suppliers you would like to be located for each manufacturer part.
• Solutions
  • Exclude Invalid SPNs - select to exclude invalid SPNs.
  • Favorite Suppliers List - opens the Favorite Suppliers dialog in which the overall list of Suppliers can be configured for this BomDoc.
  • Manufacturer Link - opens the Define Manufacturer Link Fields dialog in which the schematic component parameters that hold the Manufacturer Name and Manufacturer Part Number are identified. If there are unmanaged parts present in the design (parts not placed from a managed content server that also do not have supplier details), ActiveBOM can query the Altium Parts Provider and attempt to find that part.

This region is used to configure how the BOM Items should be grouped in the BOM Items grid.

• Items
  • Show not Fitted - if the PCB project includes variants and the chosen variant has parts set to Not Fitted, enable this to display the Not Fitted items in the BOM Items grid.
  • Designator Grouping - the Base and Consolidated view modes show common parts on a single row in the BOM Items grid. Use this option to configure if the designators are displayed individually or in ranges when a row displays multiple parts.
  • Component Grouping - opens the Component Grouping dialog. In Base view or Consolidated view, ActiveBOM identifies components as being the same when they share the same ItemID (managed) or LibRef (unmanaged). Enable parameters in the dialog to further refine how components are to be grouped.

BOM Sets provide a way of capturing the layout and configuration of the BOM Items grid and saving it as a named Set. Any number of BOM Sets can be defined.

• Current BOM Set - click the icon to apply that BOM Set to the BOM Items grid.
• Add - configure the visibility, order, and width of the columns, then click Add to capture that configuration as a BOM Set. To edit the BOM Set name click once to select it, then click a second time to edit the string.
• Update - if the configuration of the BOM Items grid is changed, click Update to re-save this configuration.
• Delete - click the button to remove the currently select BOM Set.

ActiveBOM performs comprehensive checking of each BOM Item and any supply chain data that has been detected for that item.

• Violation Type grid - displays a list of each type and quantity of violations currently present in the BomDoc. Click the filter icon to display only those BOM Items that fail that BOM Check. Note that a BOM Item can fail multiple BOM Checks.
• BOM Checks  - click the icon to open the BOM Checks dialog in which the Report Mode can be configured for each possible Violation Type.

This region of the panel is used to configure which parameters are displayed for each BOM Item and the data sources that are available for those parameters.

• Sources - in addition to the data added directly into the BomDoc ( ), the default data sources available in ActiveBOM are the schematic component parameters ( ) and the content server component parameters for managed Items ( ). From these sources, ActiveBOM generates the main project BOM Item grid. The BOM also can also include information taken from the following additional data sources:
  •  PCB - enable to include PCB location / rotation / side of board data in the available Columns for the each of the components.
  •  Database - enable to load additional component parameters from an external database (*.DbLib, *.SVNDbLib, or *.DbLink).
  •  Document - enable to include all detected schematic document parameters across all schematics in the PCB project in the available Columns.
  •  Altium Cloud Services - enable to access a broad range of additional component data for those BOM Items that have been identified by the Altium Parts Provider and show a supply chain solution.

• Columns - list of all available sources of part information available to ActiveBOM. The Columns region can be sorted by clicking on any of the heading fields.
  • Visibility - each row has an eye icon; click to control the visibility of that column in the main BOM Items grid.
  • Source - displays an icon to show from where that parameter is sourced.
  • Column Name - the name of the property/parameter as defined in the source document or as entered for a user-created BomDoc column.
  • Alias - if required, an alias can be defined to rename a column.
  • Source display checkboxes - below the column grid is a row of checkboxes, one checkbox for each data source currently enabled for the ActiveBOM . Clear the checkbox to remove all parameters from that source from the BOM Items grid.
  • Add - click to add a new Custom Column to the BOM Items grid.
