I am using OS App (v3.6.1) with the Sketchup (v2023) OS plugin (v1.6.0). It looks like the default behavior when I draw facing inside a space, is to draw them reversed. This can cause negative volume errors (see this post), which can be easily fixed by two methods:

1. Manually reversing faces (all of them I think is a good idea, but reversing one or two faces may also resolve the negative volume error). OS alpha version 3.7.0 can detect these incorrectly oriented surfaces, but I don't think it fixes them.
2. Using the script found in this post, to reverse the order of the vertices (I am not sure how to use that reverse vertices script within OS App).

The first method works fine, if a bit inefficient, while the second method (I'm assuming you either have to specify the surfaces or apply it to the whole .osm file) could inadvertently reverse faces that are correctly oriented, thereby possibly creating new/unique negative volume errors.

All this to ask - is there an option somewhere in the OS Sketchup plugin to change the default behavior of the surfaces when they are placed? Is there an option in Sketchup itself? Thanks!
