Many thanks for what? I can’t see Dave’s comment I guess.
What does that mean. Not supposed to work from within Sketchup?
It’s not supposed to work in SketchUp 2018 or earlier because as I wrote to you back on September 20th, the 3D Warehouse no longer supports those versions. You are using SketchUp 2017 Make so the 3D Warehouse user interface shouldn’t be expected to work anymore.
