Offset issues (resulted in few layers) and became a bad mesh afterwards

help! i have accidentally offset a very thin layer to my subd then it became 1 geometry. afterwards, i offset again and now there’s 4 layers and after meshing it, it has become a bad mesh that even meshrepair can’t fix. please help, urgent.

Hi @may_yip_mei_qi
Post the file, please. It’s close to impossible to tell from screen grab what’s going on. If you offset a Sub-D, the resulting object can just be split along the edgeloop to “retrieve” the original - Use Split with the Edgeloop option for that. If you offset the now thickened Sub-D once more, it should become an independent object, that can just be deleted. If they are, for some reason, one object, you could try to use ExtractControlPolygon on the Sub-D, run SplitDisjointMesh on that resulting mesh and delete the mesh objects you don’t need - and the convert back to Sub-D using ToSubD. But again: Post the file instead of having people guessing what’s gone wrong.
