Hi, I've created a floor plan using the line function then copied 2 references of it and created a plane for the floor and created an editable poly and extruded upwards for the walls. The main problem I am getting though is that when I want to cut in a window or door to the walls I am only able to do it on the poly face I am looking at. Which obviously means I then have to align the vertices on both cuts and then create some poly's for the insides of the window. I am pretty new at this and wondered whether I was going about it the right way. The house is a pretty simple layout but I'd like to get it as close to the original building as possible. I have also tried using the slice plane tool but find that it is quite difficult to get the desired lines in it. Perhaps I just need to practice it a bit more. Any help would be much appreciated.
