This group is a place to discuss using Trimble SketchUp for 3D printing.
SketchUp Make can be downloaded for free here: http://www.sketchup.com/download
To get SketchUp working for 3D printing you'll likely want to start with this STL Import/Export plugin
SketchUp plugins can be pretty handy for making your 3D designs printable. What is everyone using on their installs?
My current must have plugins are:
CleanUp³ - Removes stray "orphaned" lines from your models. Great for finding those hard to find parts that are keeping your model from being a manifold mesh.
Weld - Turns multiple edges into a single polyline.
Solid Inspector - Helps you find issues with your models that are keeping it from being a manifold mesh.
Shell - Adds thickness to single walled models. Somewhat finicky but it can easier than modeling complex shells on existing objects.
In case you missed it, Sketchup 2018 is Pro only.
But they have made a free ONLINE version available, except that you cannot use any add-ons. So if you have Sketchup 2017 and want to use your add-ons, don't delete it.
Anyway here is the link to the online version of Sketchup 2018:
I noticed there were many groups focused on just one type of designing program, and I wanted to make a group where anyone can discuss designing, no matter what they use. If a lot of experienced designers join this group, it can be a big help to beginners just learning the skill (not that I know much).
