So I was just wondering how I would go about meshing (or mating) two gears together on this online CAD program I use called Onshape.
Thanks y’all!

You mate them to their axels (which should be revolute mated to a bearing). Then, you click on “gear relation” in the toolbar, select the two revolute mates, and choose the ratio.
It’s mentioned here on the forum not infrequently…
I also suggest the onshape help docs and tutorials, they are actually pretty great.
@KDburneraccount: OnShape’s help system is pretty extensive. Here’s a video discussing gear mates: Assemble Gears. I’m assuming you’ve already taken the time to learn the basics of mating parts; that is, you’ve got the gears assembled and they spin, but you want to mesh them at the proper gear ratios.
@zrteh : OnShape is a high-end CAD system, founded by Jon Hirschtick and John McEleney who where former CEO’s of SolidWorks. When SolidWorks was acquired by Dassalt Systems (who also owns the other high-end CAD system called Catia–(well, there’s also Unigraphics NX, too.)), Jon and John started OnShape to develop a high-end CAD system that took advantage of cloud computing. They say is is sort of like the “google docs” of CAD.
Neither Catia nor Unigraphics NX offer educational licenses, however, so if students want to learn a high-end CAD, it will be SolidWorks or OnShape, or perhaps Solid Edge.
Here’s more information about various CAD software available to robotic students: CAD for VEX Robotics (2).pdf (300.8 KB) .
A quick Question here, but how would I cut a C- channel on onshape?
To cut a part in a 3D CAD program (this applies to all CAD, not just Onshape):
First, some background. Parametric CAD uses several file types, parts, assemblies, and drawings are the main types. Part files contain the geometric math data for a particular part. Assembly files contain the data to mate part files together (they don’t contain any part data themselves). Drawing files contain data to arrange drawing views and show annotations.
If you’ve been doing basic CAD, then you’ve learned to take premade parts (perhaps importing .step files from vex, or using one of the community-made parts libraries), and assemble them together. This only goes so far, and there will be a point when you need to customize a part. Here’s the basics:
Specifically for OnShape, here is one way to cut a part.
Thanks so much. Your answers definitely help me figure out things easier and faster.
