By-products may be created during 3D modeling – I mean auxiliary surfaces or unnecessary solids. I think, that everyone should clean up after themselves after finishing work, i.e. remove all unnecessary objects.

We do this through surgery Delete/Keep Objects. Of course we choose this option, where there are fewer objects to select.

However, I wanted to draw attention, that you can also do it by clicking on the selected objects, but per folder!

It makes sense then, if we want to delete the entire contents of the folder. A prime example are surfaces created during mold tooling. To remove all surfaces, right-click on the Surface Objects folder and select it Delete/keep objects and next Delete objects.

You don't have to expand folders and manually indicate the surfaces to be deleted!
