To chop off stuff, there is an option in Blender, I believe, to delete disconnected parts of a mesh. You can also use the removed doubles option to remove overlapping vertices. If you want to remove triangles as well, you can press Alt+J to remove them as well.

  • $\begingroup$ Thanks I'll look up those options :) I wonder how I can select and disconnect those parts first though? $\endgroup$ Jan 12, 2020 at 13:52
  • $\begingroup$ I think there may be a select option in Blender to select disconnected parts. Actually, nevermind on that part. If you press A to select everything, you can press Alt+J and remove doubles and it will be able to determine what is disconnected and what is not. Those are options that would probably be better to have as the last step. First, you need to deselect everything (Alt+A) and then click on the option that says to select disconnected edges. After that is done, the disconnected parts should be gone and using the two methods I mentioned earlier, it will help to clean up the model. $\endgroup$

  • $\begingroup$ Thanks, that's very helpful :) however I still don't know how to actually disconnect the parts I don't want, does anybody know how to do this? $\endgroup$ Jan 15, 2020 at 7:08
