When using Autocad STRETCH command on an AS model, most objects stretch/move just fine, but a few do not:
Nodes (such as used in stiffener joints)
Special parts
These items are not moved in a stretch command and so have to be moved afterwards.
At the least, this is inconvenient, but at worst could be missed.
If they are fully inside the stretch selection window, they should be moved along with everything else!
