Perforated 3d cylinder

Hi.

I'm trying to make a perforated cylinder in 3d for Autocad 2006. I first extruded the cylinder then placed one hole. I did a polar array to get the holes to go around then I did a polar array down. I ended up with about 2000 holes and when I tried to do a mass subtract I got an error. I was wondering if there was an easier way to solve this problem as subtracting 2000 items in smaller batches is still not an attractive option

Thanks

2000 holes, wow!

Could you make but a small portion (a sub-assembly) of the cylinder (height-wise), subtract the necessary holes, make a vertical array of the required number of sub-assemblies, then union it all together?

I dont see why that wouldn't work, Thanks for the nudge in an easier direction

I was expecting that by now someone else would have come up with a better idea or that Lee Mac would whip out one of his nifty Lisp routines that would do it in the blink of an eye.

What is this for?

I think Autocad may have trouble with 2,000 holes.

Could you get away with using an opacity map or do you need all the holes to actually be part of the cylinder?
