The attached file contains only 2 hatch made with Hexagons pattern:
1) A2013: if I use the command Hatch > Custom I see many unused patterns (I think from Microstation), see image
2) Bricscad (all): same command I do NOT see the unused patterns
3) A2013 + Bricscad (all): if I use the command -Hatch (not GUI) _p ? > I do NOT see the unused patterns
4) AutoCAD 2019: I get Fatal error on open (not solved!!!)
9) Question: How can I clean all the unused patterns?

I assume that these *.pat references in fact point to files. Which would explain the differences you see between AC and BC. Have you searched for these files on disk?

you're absolutely right, I never realized that in my 2013 Mechanical version (ONLY Mechanical) I had all these pats :embarrassed2:
I'm trying in every way to understand why a stupid hatch can crash AutoCAD, is a problem that I have in many files… :tickedoff:
-
I have a hunch that the fatal error is related to the boundary of the hatch entities in the dwg. The generated boundary in BC looks strange.
-
Thanks for your time, I have another example more complex, no problems on BricsCAD/AutoCAD except AutoCAD 2017/2018/2019 :rolleyes2:
-
The complexity of the generated boundaries suggests that these hatches were created by an application or a different CAD program. I notice gaps and splines in the boundaries in both dwgs.

Yes, that's what I think too, maybe it's MicroStation... :knuppel2:
