In my use case for Revit, we model many objects for 3D printing, which we need to export from the program. The STL plugin does this mostly well, but it has some substantial flaws. For example, the detail level cannot be adjusted, so objects almost always come out with lots of triangulation artifacts. So I went digging through the source code for the STL plugin and found that the triangulation method took a quality parameter which appeared to do what we needed, and plumbed it up to a slider on the main screen for the export plugin.
An example of a file with quality set to 99% (ending with "shiny") and a file with the default Auto quality (which is what it would always produce before I modified it; filename ending with "mediocre") are attached to this post.
