A short tutorial on converting laser scanner data into solidworks surfaces.
Things you need:
Laser Rangefinder--you either have one or you can build one e.g. http://www.david-laserscanner.com/
Acquring Point Cloud
Use the range scanner to get yourself some data. Assuming you can only scan one side at a time, you'll want to have overlapping scans to get good alignment. If possible put some landmarks onto your surface e.g. putty/play-doh.
