I found a useful plugin from TIG: http://sketchucation.com/pluginstore?pln=TIG_save_all_components. (before doing this, use the purge plugin!)
For now this works well.
And in Layout I automated the date and drawingnr., this saves me already a tiny bit of time.
Also the generate report function in Sketchup is now useful for me to make BOMs.
Is there a possibility to use the model info (. skep model) to put it in a text field in layout (such as name and description)? Or is this a wish list thing? And I always select vector rendering and background of, is it possible to set this as default Or is this still wishlist?
