Making the Doorways

After extruding the walls, I had to make the doorways. To do this, I used a slice plane and lifted it to 2100mm (as that is how high the doors will be on this model). Then I went around to each doorway and bridged the two polygons facing each other to close the gap. As seen in image 2, some of the door was are curved and to make the door way match the curve, I simply selected the 2 polygons that are facing each other and clicked on the bridge options and added 6 lines. After that, I selected all the vertices around the central line and used the soft selection tool to drag it out and round off the doorway so it matched the rest of the wall. In images 3 and 4, I was making the top of the window frames which is the same process as the doorways except I raised the slice plane to 2400mm instead of 2100mm and I made sure that I had only the exterior walls selected. to make that corner in image 3, I selected one of the vertical lines on one of the polygons, copied the X value then copied it into the same edge on the other polygon then I repeated that process for the other edges so that they met on the corner and then welded the vertices together.
