Laggy contour selection for 2d contour machining

[GilmaxCNC]

Hi, 

I have a part with a few hundred pockets that need to be machined and fusion 360 gets very laggy after selecting 70 contours and I have to wait 5-10 secs every click. I'm running core I7, gb ram, and GTX 1660 and NVME Samsung drives. I originally was using onboard graphics and bought the 3d card with no improvement. Any ideas?

Yeah...

Fusion certainly struggles once you start selecting north of 50 contour chains. It's just having to calculate a ton of data, and it just bogs it down.

Graphics card will have no effect on this, as it's the CPU that's bogging down.

Your part looks like an excellent candidate for Pattern > Rotation. Can you share the file?
File > Export > Save to local folder. Return to thread and attach the .f3d file in your reply.
