Get and Set Blocks Data in Any Document Example (VBA)

This example shows how to get blocks data in part, assembly, and drawing documents. It also shows how to change the angles of the blocks.

 

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

'

' Preconditions: Part, assembly, or drawing document containing

'                one or more block definitions

'                and block instances is open.

'

' Postconditions: The angles of all block instances are modified.
