I'm not a sketchup user either. I updated my sketchup to 2017 and while the TCP did create a menu item of a sketchup file the file is empty as far as I can tell.
I exported the drawing as a dwg/dxf and sketchup imported that fine... But that kind of import changes all of my solids to mesh. Another downside of exporting is that my layer file structure gets jacked up since I create certain layers for certain assemblies and then use sub-layers within each assembly for individual parts. AutoCAD doesn't support that either...
I would like to try the R13 export. Sketchup looks like it will now support solids so if I can import the drawing as solids it would be preferable.
The drawing is for my vacuum platter turntable. I'm attaching a photo of the work in progress and a link to the drawing for giggles.https://www.dropbox.com/s/kkscvkt4628jiwv/Loft%20Wall%20Millwork%20Profiles.tcp?dl=0
