[Cold Fusion]

Once again, need facilitates creativity. I've got lots of parts that are 2d with lots of holes and odd pockets. This would be a pain to do with point cloud system. Perhaps we could bring the operator into the picture a bit more. If the entire system could be moved by hand, it would definitely improve the quality of the data received because it would only be the necessary points determined by the user.

So here is what I thought of. A free sliding 2 axis frame similar to a tabletop cnc router. The Z axis could be a simple sliding axis with a leadscrew for raising and lowering a stylus. The key to the design is low friction and minimal skew. There are two options for encoders. Linear encoders could be installed along the rails, or rotary encoders could be attached with timing belts.

Now, what I'm confused about is inputting the data into Cad. With this type of system, isn't it possible to get arcs and lines instead of a point cloud system?

Have I completely lost my mind, or does this idea have potential?
