sketch-up for education
There is now a browser version of Sketch-Up that works with the G-Suite apps. Just login with your G-Suite education account and you can build 3D objects. There are tutorials to help you get started. You can make building and put bricks or shingles it. There are tools to help with moving around the object you have created. I would recommend watching the tutorial video before getting started. The projects are save in your Google Drive.
