Hi there. I tried to mark the dimensions of my model but it won’t work. I click the dimension button and nothing happens. What can I do?
Could you be more clear about what you are trying to do? Are you expecting SketchUp to automatically insert dimensions on your model when you click the Dimension tool?
open the ‘Instructor’ window and look at it’s options when you click Dimensions…
