3D Editors

I’m looking for a 3D Editor (Free, preferably) that allows you to outline your model and/or specify exact dimensions (without the use of pure code).

I have used Meshmixer and Memento, but they are a bit more sculpting reliant, and I’d like to design my mesh face by face, vertice by vertice.

I hate Blender. The program makes no sense.

I think you want ProBuilder in Unity. It will allow for you to build models. I am sure there are plenty other assets to make Unity better for modeling. I have never used it, but I’ve heard good things about it. Good luck!
