Does it get as bad as OpenSCAD? I found that anything even remotely complex using OpenSCAD brings the machine down to a crawl. And I'm on an overclocked 5930K with 64GB ram ;-)

I'd be very curious to see a couple screenshot of your project! I used Google Sketchup to do landscaping last year around my house; I wonder how this would compare...

The design is a bit crude, but the goal was to get the structure's dimensions right. And it worked!

Try throwing render() around heavy blocks of code. That should speed up successive renders quite a bit.

Have you tried freecad? I think it uses openscad as backend but has a slightly better (and faster) UI.

It uses Open Cascade: https://www.opencascade.com/
