Hey guys, I am having trouble with a file I have done for a centre cab. Can anyone tell me how i could go about converting this file into sheet metal. I am looking to have a joing down the front of the cab between the radius bends, and those panels will go all the way to the back., I will add material to the bonnet to acheive that bend then cut it off, the screen area i was looking to do in 2 peices and the roof its own part. I can get any of them to convert to sheet metal, what am i doing wrong??
