Hello Kris! ConDoc LT is the default drawing set on install. When you run the tools they will snapshot the visibility of tags and hidden geometry. So for an elevation, you might hide trees and people, then run the Elevation tool. You can always update the scenes manually after you create them with ConDoc. Check the tutorials! Let me know how it goes!
You can switch your model units through the SketchUp interface. Window > Model Info > Units. Adjust the dropdowns as desired.
You might consider creating a template… Click the File dropdown > Save as Template…
When running the ConDoc Export, the active scales are pulled from LayOut. You can adjust which scales are shown within LayOut, click the Edit dropdown > Preferences > Scales. Modify as desired, be sure to fully close and restart SketchUp and LayOut to see the changes in the ConDoc Export.
