[OS big Sur - upgrade problem]

I've just upgraded my system to Big Sur.  vector works now has an unusual condition. When I draw an object (free hand line for example),  it remains invisible until I move my mouse scroll wheel. Which means I can't see what I am drawing until after. Even deleting an object has this condition.

affected tools seem to be,  free hand line, Text, Callouts. 

I'm wondering if this is a problem with Vectorworks or OS big Sur?

 

[V'works exporting into .dwg files]

I had similar problem with the DWG export stopping, apparently the file name had an unusual character in it. once I adjusted the file name I could export.

[Converting VWX to DWG & vise versa.]

I am hoping someone can help me with this. I need to send shop drawings to an aluminium panel producer. The VWX files we do are great on our design end, but when we convert to dwg i get nothing but complaints. I only send stripped down versions(no symbols, or anything strange) just rectangles, polygons, circles,  labels (I convert them to be just text & polygons). I put everything into a new file then export. The CAD guy, at the shop,  says he can't use the circles in his panel software because they show up as segmented series of lines. I have purchased an Autocad lt licence to help. I discovered my VWX skills don't transfer well to AC and I would rather not spend my time learning a new program. I'm hoping I'm just missing something simple, I guess I just need to know if maybe my procedure is incorrect.

 

Thanks.
