Right now it’s tricky. You need to:
- Save your my.sketchup model in Trimble Connect - requires a (free) Trimble Connect account
- From a copy of SketchUp, import the model from Trimble Connect.
I haven’t (yet) worked with Trimble Connect, so I don’t know if this will work if your Sketchup License is 2015. If it doesn’t work, then get a copy of SketchUp MAKE 2106, use it to import from Trimble Connect, then Save it in 2015 format.
Sometime in the (hopefully near) future, my.sketchup will be able to upload components directly to the 3D Warehouse. One GREAT feature of the 3D Warehouse is that uploaded models are available in multiple formats, including 2015.
My evidence to document my assertion that saving to 3D Warehouse is planned? Go to my.sketchup.com, create a simple model with a component. Then select it, right click on it, select “3D Warehouse” and you’ll see three greyed out options, one of which is “Share Component”. I’m interpreting the greyed out action as an almost promise that it will be available in the future.
