Why does PRESSPULL sometimes fail even when the area looks closed?

[indiancad]

Have you ever tried to use PRESSPULL on what looks like a completely enclosed area, but AutoCAD refuses to create or extrude a 3D solid?

I've discovered that sometimes, the visualized boundary can be misleading. The presence of a small gap, overlapping objects, or objects that aren't actually forming a valid closed area can inhibit PRESSPULL's ability to create or extrude a 3D solid.

Instead of redrawing everything, I would first try using BOUNDARY on the perceived enclosed area. If it fails to create a closed boundary, I would look at the endpoints and attempt to fix the gap or overlapping geometry.

As soon as there is a valid closed boundary, PRESSPULL should be able to do its job.

Have you ever encountered this problem while trying to create a 3D model? What was the cause in your case?
