Hey Hu,
Do you have a picture of it? That would help in coming up with "cost effective" ways to digitize it.
If it's got constant radii curves, then touching can work, it's just time consuming. I made a ball nose "touch probe" from a piece of carbide blank and used the usual rolling paper method. I then took the points from the radius ends and used them in a demo version of Bobcad to create a drawing. It took a while, but it worked. The things we do when we don't have a budget......
