fix mesh by "merge"

I often encounter object that behave "weird" in the s3d, for e.g. https://www.thingiverse.com/download:1550926
what they have in common are "structures" inside the object and what's worse, most of the mesh manipulation programs declare them "ok" and can't "fix" them. netfabb, netfabb professional, meshlab, art of illusion.. they all see them as "ok" meshes

they normally work ok in other slicers but that's irrelevant, in s3d using "merge all outlines in single solid model" often works, but again, often does not. for e.g. the sample object I linked does not work ok.

The only "free" way I figured how to "fix" these objects so they can work ok in s3d is to import them in "3d builder" app that exist in win10 and do "edit/merge", this will merge all shells in the part into one single shell and the exported part will work ok in s3d. The solution works good but requires win10 and that's not always accessible, takes a while to boot up the vm etc.. so having something like this in the s3d itself would really be good :)

Did you already try using the Mesh > Separate Connected Surfaces option in S3D? I have used that for parts like this in the past.

tbh not for these few objects I had issues with.. trying now... wow - it works :D thanks, I was expecting "merge all outlines in single solid model" to solve it (but it messes up objects usually more then it solves :( issues ) forgot about this one, this one solves the problem 1/1 :D

This is such a useful little feature that was quietly added...I think...in v3. No fuss. No song and dance. And I think it was one of the best additions to the software.

The only thing to watch having used this function.....avoid auto-arranging parts on the bed.....or at least don't use it while the kids are within hearing range!!!! ;)

yes, it works waaaay better then one would expect :D this object I mentioned in the original post is perfect example

yes, "Grouping" option for objects on table would really help out here :D
