Inserting Doors and Windows in Your Sketchup Model
You can make openings in the walls of your SketchUp model house in a couple ways. The best option depends on what kind of building you’re modeling, whether you’re using single-face or double-face walls, and how much detail you plan to include in your model. You have two options:
Use SketchUp components that cut openings. The SketchUp 3D Warehouse contains scores of doors and windows that you can download and use in your models. Some of them cut their own openings when you insert them in a face.
Here’s the catch, though: SketchUp’s cut-opening components work only on single-face walls, which means that they’re only really useful for exterior building models. If you’re building an interior model, you have to cut your own openings.
Cut openings yourself. For double-face walls, this is your only option; luckily, it’s easy to do. Basically, draw the opening’s outline and then use Push/Pull to create the opening. The process is the same for doors and windows.
