I needed to test the 3d printer so I took our school mascot (Go Bobcats!), imported as a 2d image, and started extruding using PressPull. Once I got half way done extruding, AutoCAD froze. I tried updating, force quit and restarting, and didn't find any limitations on licenses.
Any solutions welcome
What do you see if you do a Zoom All?
Try this.
Right click on View Cube set to Parallel rather than Perpsective.
Zoom All
Rotate around a bit.
Zoom All again.
Click on the Top view of the view cube.
See anything unexpected?
Get rid of it if you do.
Union
select all.
This is what I see.
Also, when I try PressPull (the problem description) - not expected behavior.
Until I follow the steps I suggested earlier.
Model (image you posted) is wayyyyy down there....
But without any feedback from the OP....
