Weird Faces

Hello I’m new in this forum, and i’m new also modeling.

I’ve got a problem modeling a cube.

I try to transform the vertices from both sides of the cube, but always one of them makes a weird face.

I would like to know which problem is causing this behavior so i can solve it.

Thank you in advance.

What you have there is a so called “concave quad”, a face with four vertices that has a “dent” in it. Those should be avoided as they can produce artefacts (as you see) in the viewport and the later render. So, you can either try to make that quads convex or just split them up into triangles (in a simple case as this):

Thank you that solved my problem :wink:
