Get Bounding Box Example (VB.NET)

This example shows how to get the bounding boxes for the selected feature and face. This example also shows how to draw 3D sketches depicting the bounding boxes.

'----------------------------------------------
' Preconditions:
' 1. Verify that the part to open exists.
' 2. Open the Immediate window.
'
' Postconditions:
' 1. Selects the Sweep1 feature.
' 2. Creates a 3D sketch of the bounding box of
'    the selected Sweep1 feature.
' 3. Selects the top face.
' 4. Creates a 3D sketch of the bounding box of 
'    the selected face.
' 5. Examine the graphics area and the Immediate
'    window.
'
' NOTE: Because this part is used elsewhere,
' do not save changes.
