After going through a few video tutorials from Lynda I have learned a lot of new things about making a proper building in SketchUp and here is a few of them!
Making parts separate from your building
Improving windows on your 3D model
When I made windows in the past I just uploaded a pre-made window from the 3D warehouse SketchUp has. I then just tried to fit it into the space I wanted, 99% of the time it didn't fit. I did make my own windows before but they never looked very good, now that I am going through a tutorial I now know how to make windows and how to fit the 3D warehouse windows to fit into the window frames I made.
Making background scenes
Lets say you make a custom kitchen for someone and you only want to present the kitchen and not the rest of the building. You can take a picture in real life of a room or something of that sort, and then upload that into SketchUp to use as a texture and put it in place of a open window between two rooms. Another thing that you would use this for is making a scene behind your windows outside, like lets say you don't like the SketchUp view and you want to display something like your neighborhood where you would build or remodel the kitchen. Well all you have to do is take a picture with your phone of outside where the kitchen is/would be and use that to put on the outside of your windows, so that when looking around in SketchUp you can see outdoors. Like you can see here: (I did not make this, its apart of the tutorial)
Templates
I also learned how to make rimming for the walls, doors, and windows. Like instead of making a door trimming and then pulling it down to the ground you could use this tool called "Follow me" which basically lets you grab any template and have it follow your mouse to anywhere you wish, like going around the ceiling of a room, or around a door, all you have to do is select a template then use the follow me tool to pull it around a door to make a frame.
