I made a new SketchUp plugin called Plan Crafter.
It lets you drag and draw CAD-style blocks directly in SketchUp to quickly create 2D floor plans.
It’s still new, so if you find any bugs, please let me know and I’ll try to fix them.
Also, if anyone wants to donate CAD blocks to the plugin, please feel free to do so. The blocks are stored in JSON files, so you can contribute your own blocks in the same format. The more blocks we can add, the more useful the library will become for everyone.
As always, the plugin is free.
