I have made differnent fusions, the biggest is about 5.000.000 but that takes a few hours..mosty i do it overnight, start the fusionproces, drink a cup of coffee, leave the office, have a good evening at home and finaly when i come through the door my fusion is ready

Thanks for the other topic, it realy helpfull, i have something to do this weekend!

Had some success with DesignSpark Mechanical and reverse engineering its free http://www.rs-online.com/designspark/el ... mechanical
bit more work than Geomagic Design X but good results for free ;-)

For some reason we have holes in scan results.
It's important to fill those holes with surfaces.
Holes are surrounded by surfaces.It's important to choose a proper algorithm to fill them by using curvature , tangency or contact algorithm.

Here is an example by using " geomagic studio "

Hi,

Here is a step by step reverse engineering sample using surfacing tools.
The parts has scanned using david laser scanner.
