Using Sketchup Make 17.0.10349.
The file was initially made on Sketchup Pro on Mac. I transferred to my PC for rendering on Sketchup Make and VRAY 3.6.
The file was extremely large and slow despite only containing basic geometry and minimal imported elements. I purged the file, gaining about 10mb, I then slowly went through deleting elements and purging to locate the problem and eventually had nothing left.
I zoomed extent, turned on hidden gemometry and deleted everything. The outliner contains nothing but the file name. VRAY has no textures or lights, etc. I did a final purge. Yet the project is still 360mb.
If I copy and paste the contents to a new sketchup file it is 30mb.
I really dont want to have to transfer to a new file and lose all the views and potentially VRAY information.
Have I missed something?
