Hi Igor,

I know for sure that this is not correct, because the only feedback that I've had up until now is from people who are using it successfully for their work.

Yours is the first feedback about the groups issue.

The UI is only one of the issues (although certainly a big one) - it also takes me a lot of effort just to implement numerous configuration options, especially in a case like this where the documentation for the library is poor and where the overall mechanism has many things to look out for.

Just writing the geometry well involved quite a lot of work due to various issues that had no mention in documentation, like vertices cannot be closer than 0.001 units apart, exporting polylines will crash if you create them with line segments and the vertices of the line segments get merged with existing geometry, etc.., etc.., etc... it's not like I can just throw a switch and instantly have new export features working totally smoothly, on the contrary it takes a lot of effort to make them work well. Particularly in something that has proven to be delicate and have numerous issues.

So in general these things get developed at a somewhat slower pace - it is not feasible for me to just load in a ton of options "just in case" for things that I'm not sure are even going to be used or not.

So instead of just saying you want options for all kinds of different behavior, it helps me a lot if you could prioritize what would be the most important for you, so that I can implement things one step at a time with the most important stuff getting implemented first.

From what it sounds like, an option to export each MoI object as a separate group would be the highest priority thing, is that correct? I think that I understand how that should work. That seems like it could be the best starting point for the next feature work on SKP export.

For layers or materials, that one could need to wait a bit until I get some more feedback on what would be the most expected way to have that work...

Are any of these lessons online or in the official SketchUp documentation? If you can point me towards some documentation that gives some official recommendation to not assign geometry to other layers than layer 0 for example, that would definitely help make it easier for me to focus on that as the main method to process stuff.
