Remove inner wall on thin shell model with complex geometry Is there an easy way to remove the interior wall on a model with complex geometry? The model was imported from an STL file for a object which is very large, but has very thin walls. One of the walls needs to be selected, then deleted in the edit mode.



Note: Using the mesh selection tools requires a huge number of steps to separate the mesh.
Maybe your inner mesh have different Normals, try selecting one of them and go to Select > Select Similar > Normals

And then see if it selects them all
