Hello, I found a place around here that can cut plexiglass with laser. I was thinking that I might use it to make things like head plates and so on. I would like to make my own drawings in a vectorial form rather than relying on them for drawing. The problem is that I don’t have a pc anymore. I used to use autocad and it worked wonderfully well. Are you aware of a software for iPad that can make technical drawings like autocad for tablet? I found so many in the store. I don’t know which one to use. Maybe you are familiar with an app useful for this kind of stuff and Lutherie in general?
Many thanks Enrico Schiaffella
