![]() ![]() Ideally, you would want to model the original design intent. ![]() There are always manufacturing variations. But, keep in mind that even if the part works, it is not really produced as it was drawn. These were areas like the part of the set that depicted the perimeter of the ground around a rolling set.įor your work, you have a part that is known to work well. There were some parts of the object that didn't need to be very accurately reproduced. I just wanted the tools to make it faster for me to re-interpret the object, and make it easy to interrupt the process to insert my own design skills. In other words, I really did not want to accurately re-create the object. No machine is capable of making those kinds of decisions. well unless that 0.1" of space was for clearance to another part that had to go there at a later time. And if something were 6.1 " from an edge, I was strongly motivated to change that to be 6" exactly. I briefly considered a 3D laser scanner, But, I immediately realized that I wanted to model to have walls that were perfectly flat, and perpendicular to the floor. I would start by measuring a small model of a theatrical set piece. My job was to design the internal metal framework of the set pieces. (attached is an image of one of their more recent productions to get a sense of its scale). Yes, there may be some distortion, but you will probably need to do some test parts and then adjust dimensions if necessary.įor a time I was creating 3D CAD models for a theater. Sheet metal work is not a process that is considered highly accurate. Upon re-reading the thread, I agree that this may be the best option. The part will be too big for an 8 1/2" x 11" scanner. I also don't know what kind of accuracy I could get from a 2D scanner, and whether I could accurately stitch scans together. But I am not sure I could do this without stretching the material. That process would give me a "developed blank" The material is soft, thin aluminum. I still wonder if my other approach (physically flattening the chassis, and scanning it on a 2D scanner would offer the best results. ![]()
