Full Version: remove 6 edges that don't do anything

I can't quite remember how I got these (I was making a cut-out there and maybe removed it badly).

Question 1: how do I remove them? ...they aren't causing any problem per se, but they get in the way of my view as I will be putting another cut-out there.
- I have tried creating a 2nd solid that covers it and boolean-union.
- I have tried to separate and delete them but that doesn't work either (or I'm doing it wrong).

Question 2: Is there a cleanup tool to remove edges that don't impact the surface geometry?

Question 3: related question: If I did create another cut-out there, is there a simple way to resize it (without removing it entirely and creating a new one)? ...I think this may be how I got these edges in the first place.

Any tips greatly appreciated!

In v5 you can use the Transform > Move command on selected faces to edit openings.

Check out here for some demo screencaps:

brilliant - thanks.

...just downloaded the latest beta and am playing with it :-)

...are the files backward compatible with v4?

Yes.

If you can please upload the .3dm file that would help me answer your other questions too.

Hi James, there is a new "RemoveAndFill" function in v5 that can be used for this case.

You can access it by selecting the face:



Then use Shift+Delete:



It's also possible to do an "untrim" to erase a trim boundary to uncover the underlying surface. That's done by separating out a surface so it's not joined and then select all edges of a boundary and use Delete.

Some info on untrim here, but Shift+Delete is more convenient:
