Disable Selection of Faces and Edges Using a Pre-Notify Event Example (VB.NET)

This example shows how to disable the interactive selection of:

  • faces in part and assembly documents

  • edges in drawing documents

using a pre-notify event.

'------------------------------------

' Preconditions:

' 1. Part, assembly, or drawing document is active.

' 2. Run this macro (press F5).

'

' NOTE: Tools > Options > Stop VSTA debugger on macro

' exit must not be selected for this macro

' to run to completion.

'

' Postconditions:

' 1. If a part or assembly document is open,

'    then you cannot interactively select faces in

'    that document.

' 2. If a drawing document is open, then

'    you cannot interactively select edges in that

'    document.

' 3. Click the Stop Debugging button in the

'    SOLIDWORKS Visual Studio Tools for

'    Applications IDE to re-enable the

'    interactive selection of faces in

'    a part or assembly document or edges in

'    a drawing document.
