Hi...

Now I still considering these software :

Looks like Geomagic & Rapidform more concern on product design ( CAD ). For Meshlab, it has some limitations.
I still dont have final decision. Still watching some of the video of those product above to see more deep the features.

Thanks for all your help guys...

I've worked with Geomagic Studio many years ago for handling point cloud data from human scans and sets. At the time we tried Paraform 3d(don't think it exists any longer) and Rapidform : It was precisely in the most complex circumstances that GS was out shining the others(particularly in repairing fine defects after the tessellation, like overlapping surfaces and inverted normals). Also it has a very high quality system for converting the point data to nurbs surfaces/subd's.

Autodesk Plant Design should have point cloud tools (all current AutoCAD based products do). I am not sure how good they are since I don't work with point clouds.
