align problem with teapot

[reachyours]

are there any way of aligning scanning of teapot. the surface of teapot is almost same but the handle and the delivery port. when i align in free mode, DAVID can not recognize the right surface. so i put some tags on it . it doesn't work either.
is ther someone give me some advice.

Use the contact pair selection when aligning.

That should get things aligned properly.

I'm not very good at alignment but I will share what I know and apply.

Generally speaking
-Try different alignment options till you get a satisfactory smooth transaction between scans like the posted images.

For the teapot
-If the free option doesn't work for 1 trial. You can undo and try 3 or 4 more times! The software tries different probabilities.
-You don't need to use tags for that teapot. Because it has clear identifiable features.
-If that still doesn't work; What I would do is to manually drag and overlap the scans as can be seen from the posted images.
-Then click the "pairwise fine registration".

Good luck!

Try using the marked contact pair for alignment... It should properly align both scans.

For now, David doesn't have the option for "n points" contact pair registration.
