I've created an exporter to bring geometry from SketchUp 23 into THERM 7.8, which I'm sharing for anyone who may find it useful. See attached and video below.
The tool exports DXF files with specific formatting rules. The process is straightforward: save and replace, then import directly into THERM (retaining inches as units). Currently, it's suitable for rectangular geometry only.
I've labelled this as version 1.0, as I anticipate future updates. Feel free to use or disregard as needed. It's proven quite efficient, particularly when defining architectural geometry with clearly articulated links and dimensions in SketchUp. Needs to be added into the subfolder - C:\Users\xxxx\AppData\Roaming\SketchUp\SketchUp 2023\SketchUp\Plugins
