Welcome!

Want to supercharge your modeling workflow, explore new markets or learn a new skill just for the sake of learning? In any case we are delighted to see you here! With extensibility, you can save time, increase productivity and expand the possibilities in SketchUp.

If you've never coded before, you can start with Writing Your First Code and move on to Basic Development Environment and Creating a SketchUp Extension.

If you already know how to talk to computers but are new to SketchUp, Creating a SketchUp Extension or Lengths and Units in SketchUp could be a good start.

If you have a few SketchUp extensions under your belt but want to be better at what you are doing, maybe the UX Guidelines or Trimble Modus is for you.

Other useful resources are our Ruby API Documentation and our developer community forum.

Enjoy!
