If i roll back the part to where the grid cuts are suppressed the file does not take a long time to load and rebuild. However, I would like to be able to see the grid when I am inserting the 3/4" diameter holes. I have the image quality as low as it can go and i am not sure what else to do...
My system specs:
Graphics: Nvidia GeForce GTX 1070
Processor:Intel i7-8700k CPU @ 3.70GHz. 3696 Mhz, 6 Cores, 12 logical processors
Installed Ram: 16GB
