VSTA Macro which activates feature manager tab via SOLIDWORKS API

This example demonstrates how to activate standard tabs (feature manager tree, property manager, configuration manager, DimXpert manager, display manager) in the feature manager view using SOLIDWORKS API.

Specify the tab to activate using the FeatMgrTab_e enumeration
Run the macro (VSTA3)
Active tab is shown in the message box
Specified tab is activated
