2d import CRAZY SLOW

[handsmalone]

I am trying to import a Knurling pattern so I can trace it.. But for some reason Fusion becomes unusably slow.. I have spent hours getting to the point where I can "project to surface" and its just sitting and spinning, using 20ish percent of my CPU and a few gigs but doing nothing (for about an hour now).. .I have attached the svg.. Its got a few lines but not crazy..  I have also tried importing the file as a DXF.. and Fusion is just as unworkable with that import to.

There are almost 2000 curves in this sketch.  That will never work efficiently in a Fusion sketch.  I would not recommend importing an SVG with that many curves into a single sketch, much less try to project each curve onto a surface.  The performance will never be acceptable.

What are you trying to do with this sketch?

I am trying to apply a knurling pattern to trace with an engraving bit... It being intricate and detailed is kind of the point.  and I am kind of shocked that 2000 lines are such an issue given modern computers.

Also noticed that Fusion won't use more than about 1.8gb of ram or about 15% of the processor

If you can, I would try splitting this into multiple smaller sketches.  Fusion sketches get pretty slow after a couple hundred curves - because this is not just geometry, but it is a constrained solve.  Even though you have not applied any constraints, there are still constraints that connect points to adjacent lines.  Yes, it could be faster, and we are working on that, but at the moment, it does have this performance limitation, unfortunately.
