AutoCAD 2020 crashes/freezes whenever hatching

[Anonymous]

Hey there, I'm using AutoCAD for architectural drawings, but it has problems hatching. The first few hatches cause the pinwheel to spin for 10-60 seconds. The next few cause the program to freeze for a while, sometimes for 5-10 minutes leading me to force close. Once there are about 7 hatches I am in serious trouble...it will either freeze for extended periods of time or crash itself.

Any help would be greatly appreciated. This has been affecting my work output and grades. 

I'm using ACAD 2020 on a 2018 MacBook Pro running OS Catalina 10.15.7.

Cheers!

Hi @Anonymous ,

Please attach screenshot of the drawing you are talking about or better - drawing itself. I want to see how complex is hatch boundary.

Specify also what Hatch psttern(s) ate you using.

Hey @maxim_k ,

It's happened every file I've worked on in the last few months. One of the
files should be attached here. Let me know if it's not.

Thank you so much!

Sorry, the file is not attached.

You need to answer in browser in order to be able to attach files to the post.

Here's one that took forever. Wound up submitting it like this although it's incomplete. Editing or changing it any further became impossible because it would just freeze or crash. Let me know what you think

Hi @Anonymous ,

I looked at your drawing.

And here are some recommendations:

1/ Try to hatch areas using "Separate hatches" option on Hatch Visor:

 2/ If you don't need complex polyline with a lot of vertices to be hatch boundaries, turn off Layers with complex polylines - "entourage" in your case. Or use HIDEOBJECTS command to temporary hide such objects.

3/ Use AUDIT command from time to time to repair errors in the drawing. I have found 1 error in your drawing relate to Hatch objects.

To say true, I don't have troubles you described with your drawing on Mac mini M1 with 16 Gb RAM. It slows down a little, but nothing more. Can you provide hardware specs of your Mac?

Try to open attache drawing - I separated hatches in it, repaired errors and re-hatched one area with complex boundaries by removing them.
