Get Selected Objects and Types Example (VBA)

This example shows how to determine what is currently selected.



' Problem:

'       There are many features and selectable

'       entities within the SolidWorks software. In most cases,

'       it is obvious as to what is selected, but

'       sometimes it is not clear or it is ambiguous.


'       This code sample is a diagnostic tool

'       to determine what is currently selected. It shows

'       several techniques and methods to get a reference

'       to what is selected.


' Preconditions:

'       (1) Assembly document is open.

'       (2) Something is selected.


' Postconditions:

'       None


' NOTE: Not all features have an associated *FeatureData object.
