Merging 2 Meshes

[zero_zero]

in exocad show only your two meshes on screen, right click the Save icon, select Export Scene to Mesh (save in stl format)

Saving visible objects together in Exo will not boolean unite the meshes AFAIK

Also you can end up with non manifold parts making it a PITA to work with down the line

I'll stay on this topic too, ty for pointing out CoolHandLuke, Zero and others.

I had problems with Meshmixer combining parts too in the past.

Like when i "boolean'd" or "made it 1 part", it often still throws errors when trying to bridge between detached mesh parts,
E.G. I was trying to use two bridges and then "close holes" via inspector which often works with "normal meshes".
(i guess it's like CoolHandLuke sayd, it's gotta be a real 1-Mesh-thingy)

Maybe worth giving Meshlab a chance on such problems

no it doesn't do a boolean function. its a simple combine function, same as the one in meshmixer where you combine meshes into one object. that's a separate thing from boolean combine.

You have to save everything separate, then you'd have separate meshes to be able to work on individually. Intersecting / overhanging parts can easily throw the algorithm off trying to apply boolean functions to them. If you reimport the united mesh it has to be sound in order for exo to work with it properly.

Hey Omsk,

going back to your original problem.

If you have 2 seperate scans, you probably have to align them first before trying any of the discussed combine stuff here.

check this video for aligning 2 objects in meshmixer > Align Scans in Meshmixer

Also in Exocad you can try: start the case with the "bad scan", go expert > Tools > add/remove mesh > select Meshtype "additional Jaw Scan" and load your good "scan".

When going back to Wizard mode, it should start the alignment process for this additional scan and when done it asks you how to combine the Data.
