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

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.
