All ConDoc styles are stored in your plugins folder… path looks something like this… C:\Users\YOUR NAME\AppData\Roaming\SketchUp\SketchUp 2022\SketchUp\Plugins\ConDoc Tools\styles.
You could also just load the ConDoc PRO drawing set, click the DESIGN button, then open the styles dialog in SketchUp. Click the house icon to access the “In Model” collection. Then you can test the visual style…
Let me know if that helps!
