Im going to order the disk so I dont have to guess on bending tube anymore and now that I am using DOM instead of PIPE i have to learn how to fit it and find the center of my bends. But heres my problem. I want to design everything while Im setting at home on my azz with nothing better to do.........but the shop is 20 miles away at my buddies house and there is a computer there also which would be nice to have there as well . So how would that work.....from what i hear it can only be used on one computer so this wouldnt work out to well for me. So those of you that have it what can I do besides buying it twice?
