It’s at least the second time this is happening to me, but now I catch it. However, I can’t make a minimal file where this can be reproduced so as an example I will use a slightly bigger file. The problem is visible on many mesh parts but for simplicity, I will focus on one of the wheels.
Can you please take look at it? @Jussi_Aaltonen

Files:
unweld Start.obj (6.4 MB) - start file
blender export to OBJ.obj (5.7 MB) - file re-exported in Blender
two meshes.3dm (4.7 MB) - both meshes in Rhino file
I’m working with Rhino 7 and RizomUV 2022.
Rhino unwelds some of the mesh edges. Once they are unwelded further “unfolding” in RizomUV produces bad results which break my work.
This is a work in progress file where I do unwrapping, many parts of this mesh object show this behavior but please focus on one of the wheels.
Example
RizomUV
Please take a look at which edges are unwelded.
Exported from RizomUV as obj and imported to Rhino 7
Rhino during import unwelded some random mesh edges
Exported from RizomUV as obj, imported in Blender, exported again to obj and imported in Rhino
Importing the obj file in Blender 2.83 first and then proceeding to Rhino made me avoid this problem and it shows that there is something strange on the Rhino side.
