I downloaded a trial version of Coreldraw to experiment with, I've had the DXF importer for many years.
At times I need better vector layout control than what the 2D packages offers, and I'm constantly struggling with it.

But now the DXF importer crashes when I try and import a very simple drawing I was testing out.
I just drew a rectangle with arcs on ends, and as soon as I would try to import, designer will crash and shut down.
So I kept trying to drill down and see if I could isolate the problem.
It doesn't matter what version of AutoCAD I export for, the crash happens every single time.

I drew a rectangle version with no arcs and that I can import.

Any ideas what might be causing this?
This is about a basic as it gets, it can't be a file size issue.
I don't want to invest time in drawing out something complicated to find out I can't import it, I'm glad I start with just a simple test shape.

This, I can't import.

I'll take any advise or wild guesses you're willing to offer.

Thanks.
