hi,

i want to digitize a gas tank. later i need to redraw the tank in rhino with nurbs for further processing.

i was trying 123d catch which gave bad results.

now i am thinking of using a 3d digitizing probe on the cnc to digitize the gas tank. but i would need to mount it on a fourth axis and digitize a second run with a 90° angle. i would zero the digitizing probe at the center of rotation.

is it right that when you digitize the second 90° run i would just have to turn the pointcloud 90° back in the cad?

i am looking for a relatively cheap solution. would laserscanning , for example with the david laser scanner, be easier and faster for that?

thanks for your help,
michael
