Transform Point from Component Space to Assembly Space Example (VBA)

This example shows how to transform a point from component space to assembly space.

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

'

' Preconditions:

'       (1) Assembly document is open.

'       (2) Component is selected.

'

' Postconditions: Component's origin is transformed to a point assembly space.
