In my presentation I mentioned that Sketchup can be extended via Ruby scripts. There are some good ones by my friend Clark Bremer, although intended for Timberframing I’m sure they can be adapted for furniture work.
An overview and some related links: Timber Frame Rubies | SketchUp Plugin Index (sketchupplugins.com)
The actual Extensions require a Trimble account, but it’s free and they’re a reputable company:
Timber Framing Extensions | SketchUp Extension Warehouse
Happy drafting!
