Shark tooth

Postby davide445 » Fri Mar 04, 2016 7:22 pm

Finished to align the scan of the two faces of a shark tooth.

Any way in David 4 to merge these two faces or need I to do it in another program?

You have probably figured it out. Go to fusion menu, on the left pane there is a small alignment control panel. I would try leaving everything at default first and click on the alignment button, then the cursor becomes a magnet icon having a subscript "A," click on one of the scan results on the right column, then click on the other when the cursor has a "B" subscript.

You need to have some overlap between those 2 groups. If there is no overlap then DAVID can´t figure it out how to align them.

In this project I was finally able to align the scan using point matching with an external marker (the support).

In the new butterfly project I needed to manually align the front and back parts before fusion.

Even using the marker was almost impossibile to catch the borders of a so thin object.
