So, I have been asked to make a fabric cover for a BIG glitterball 1m diameter. And seeing as I just installed a fabric cutting CNC machine I thought this would be the first cutting job.
The ball ( 1m diameter ) cover can have a large tolerance so it slips over the ball easily so i’m not looking for sub mm tolerance, it can be oversized by 20-30 mm. Also the half sphere part of the cover stops at the equator where I add a 250mm height skirt
I have tried unroll, flatten, squish and smash and get various results, My problem is the length of the segment I flatten is longer at the equator side than the skirt segment… As I know this I can just make the skirt segments longer but is there a better way to do this that is more accurate ?
