Get Preselected Object Example (VBA)

' This example shows how to get a pre-selected object when a pre-selection event is fired.

 

Module

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

' Preconditions:

' 1. Part, assembly, or drawing document

'    is active.

' 2. If a part or assembly document is active, then

'    pre-select (mouse over) a face.

'    - or -

'    If a drawing document is active, then pre-select

'    an edge.

' 3. Run the 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. Whenever a face is pre-selected in a part or assembly

'    document, statements confirming its pre-selection are

'    written to the Immediate window.

'    - or -

'    Whenever an edge is pre-selected in a drawing document,

'    statements confirming its pre-selection are written

'    to the Immediate window.

' 2. To stop running the macro, click Debug > Stop Debugging

'    in the Microsoft Visual Basic IDE.
