Program doesn't respond after trying to project

Hello,
I'm still working on my adaptation with DSM. So far, and for projects that don't require motion studies, DSM is a good tool for me when I forget habits and work methods acquired with other software. I'll add some example images.

However, I'm worried that lately the work is difficult because the program doesn't respond after trying to project edges from faces and surfaces to sketches. It really seems to slow down excessively and then I cause it to close.

I didn't know about the spaceclaim software, and I didn't know what relationship it has with DSM, but the message after that is "spaceclaim 2023 doesn't respond". And always when I work on sketches with projection attempt. I have to say that I work with "sketch limitations activated", but with standard sketch the problem also occurs.

Many hours investigating advanced DSM properties (configuration), trying all options related to processor change etc, but without results.

I have also found that DXF sketch imports cannot be extruded and require re-drawing, but I end up finding a solution at the expense of time.

Should I take this problem as inevitable at this point?

Are there any specific program configuration tips?

Maybe the graphics card, which is already old, causes this?

Sorry for the flood of questions,

Thanks,

Germán
