Applied Parameters: ContextSensitive=True
For the component under the cursor, this command is used to choose an 'Alternate Part' for that component in the chosen variant of the design. This allows you to specify a component to be used for that variant that is entirely different to that used in the base design.
This command is accessed in the Schematic Editor. With a defined variant chosen and the compiled document view active, right-click over a placed component then choose the Part Actions » Choose Alternate Part command from the context menu.
After launching the command, the Edit Component Variation dialog will open. Use the dialog to browse and locate the required alternate part component. All of Altium Designer's component storage models are supported, such as independent libraries, database libraries and server components.
You can check the chosen alternate component in the workspace. The Schematic Editor will use the symbol graphics for the chosen alternate component. If the component is pin-compatible and graphically similar, you should see very little change. The tell-tale sign for the use of a different component is the different comment for the alternate part.
- If an alternate component is not already used elsewhere in the design, the symbol graphics for the alternate component are stored in a dedicated file -
<ProjectName>.PrjPcbVariants. This file is stored in the same location as the project file. Parameters changes for the alternate components are defined in the Variant Management dialog and saved in the project file. Using the
.PrjPcbVariants file keeps the project independent from the source libraries that were used to create the design.
- If a base component uses a graphical display mode other than the default
Normal and it has an alternate component defined in a variant, the alternate component will also attempt to use the same graphical display mode. If the alternate component does not include this graphical display mode, then the
Normal mode is used.
