hi all, i've explained my situation below. Any help would be GREATLY appreciated! i need to make a 'stencil' of sorts that is a solid 1.5mm thick disk (about 30mm in diameter) with 200um holes (separated by 500um - i.e. 500um distance between each hole) Things I've tried: I tried to make a 2D footprint of this stencil and then extrude the entire thing. My computer crashed! i guess the ram needed for this is too much. I made a 200um diameter circle, extruded it into a 1.5mm 'pillar', arrayed these pillars, then placed a 30mm diameter, 1.5mm high solid disk around the array and made a block. When i exported it to an stl format, it didn't recognize the design as a disk with holes, but as an array of pillars.. argh!!! I tried to make the disk first. draw one 200um circle and presspull it to form one hole - but i can't seem to array that hole in this disk!! ARGH!!!!! If I have to make an array of these circles and presspull them one at a time, i'll die before i finish the stencil. What to do? What to do?? I'm at my wits' end! Thank you much for any help!!
