SketchUp as a BIM tool and CAD replacement.
SketchUp has matured hugely in the past few years to become a fast-developing new standard, gaining major advantages in comparison to 2D CAD:
Instant Section Cut Fill has been built in to create finished plan section and elevation drawings.
2D drawing capability in LayOut. This is arguably an easier and cheaper solution for 2D CAD purposes alone, without talking about 3D modelling.
SketchUp's BIM credentials are also outlined in the BIM Section at https://viewsion.ie/#bim. I've written up with Revit, exploring solutions and commercial advantages rather than just BIM for BIM's sake.
The new book "https://sketchucation.com/shop/books/intermediate/227-sketchup-for-construction-documentation-2018" is a short practical course which explores the best way to professionally produce SketchUp models then convert them to live-updated Construction Documents.
