i am trying to close the open area in the front of this house. Would be the wall of the attic. How do i close it to make the rest of the wall. I was pulling edges but that left extra square everywhere so idk what to do now lol
I think you need to look into some more basic modeling tutorials, you are going about this all wrong.
Anyways to answer your question all you have to do is select the three vertices that make up the triangle and press F to create a face.
