making a 3d stencil with 200um holes

[pleasehelp]

I got it to work by doing everything in 2D, then EXTRUDEing everything at once, then SUBTRACTing the small cylinders in "chunks" (AutoCAD complained if I tried to do to many at once see below) I have no idea what at "brep" is?
It does seem to take a fair amount of horsepower (although the computer I did this on isn't a exactly a powerhouse.)

SUBTRACT Select solids, surfaces, and regions to subtract from ..



Select objects: 1 found

Select objects:


The maximum number of history nodes in a solid would be exceeded.
You may want to convert the solid to a brep.

Nesty, this is AWESOME!! I can't seem to get it though.. i tried attaching the file that i have so far, but its over the permitted limit.

Type SOLIDHIST at the command line. 0 = OFF Disabling SOLIDHIST does not remove history from existing solids, it only means there will be no history recorded for new solids.

hi
turned off solidhist. getting this error:

Yeah, I know. I was going to upload just the Region with 1650 holes in the 30 dia circle, but even that is twice as big as the upload limit permits.

Excellent! Now we just have to hope the CNC reads it correctly.

Popcorn is extra.

ReMark, nice graphic and methodical approach, but what happens when a hole falls on one of the quadrant lines, if it isn't dead center?
I believe that where you stitch it together you will run into spacing problems too, between hole centers on adjacent quadrants.

I had no problem with the holes that fell on the quadrant lines.
