Can I ask contributors to the site - I’m new to the CAD aspect of all this and am keen to spend my Christmas break starting to learn how to use the software. What would you recommend as an entry point to the tooling? (I’m basically trying to get to the level where I can build a basic garden room structure.)
Sketchup is the easiest way to get into CAD if you haven’t used any other CAD program. I suggest learning about each tool you have available in the CAD program. So for example, if you pick SketchUp, go through the following playlist and practice them.
