Reverse Engineering: Scan to CAD File

Hello,

I am wondering, if it's possible, to scan a part without a CAD File and extrapolate data and measurements from the scan and export that data into a CAD File. If this is possible, how do you do that?

Thank you!

    Yep. There is no way to get a 3D TTP scan unless it is generated from CAD or you use surface points w/ 3 sample hit.

    The start point and end point make a "line", all hit will be perp, IN ONE DIRECTION, if ya follow me. But yes, a TTP scan w/out cad will only ever be a 2D scan. I'm not saying that it will be square to X or Y or Z, but it will only be 2D in some planar slice. That plane may be 15* off your axis, but it will still only be "2D". take a plane, ANY plane, and that is the CUT PLANE and that is the 2D 'slice' you will get from the data, the probe will ONLY be comped "IN" that plane. If the shape 'rocks' (twists, whatever) in and out of perp to the CUT PLANE, you will NOT get correct probe come.
