I downloaded SketchUp Make 2017 (as my SketchUp Pro license expired recently) only the download from SketchUp/Trimble is just SketchUp Pro again!! ARRGHHH!!!! Anyone else found this?
Is there a fix?

I can't find Chris Fullmer or his tool on the Extensions Warehouse or internet. Do you have the name of that tool TIG? Would be really useful! Thanks.

Not quite what we're after though trip- imagine doing that with 1000 polys and lines by hand
