Disable Selection of Faces and Edges Using a Pre-Notify Event Example (VBA)

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.

 

Module

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

' Preconditions:

'       (1) Part, assembly, or drawing document

'           is active.

'       (2) Run this macro (press F5 and click Run).

'

' 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 Reset button in the Microsoft Visual

'           Basic IDE to re-enable the interactive selection

'           of faces in a part or assembly document or edges

'            in a drawing document.
