# TechDrawViewSet
#
# This allows you to take a view of your part from the the 3D viewer
# and insert it into a TechDraw document.  It's useful for when you
# need a tech drawing of your part from a weird angle.
#
# 1. Create a TechDrawing and insert a view of your part.
# 2. Open your part up in the 3D viewer
# 3. Orient it however you want it
# 4. While keeping the 3D view active/visible, select the TechDraw
#     Object/View from step 1.
# 5. Run the macro.  This will automatically adjust the direction of
#     techDraw object to match the 3D view.
