Levers and Mates

marc_crompton

I have a student who is trying to create a simple lever (or a see-saw).  It is basically just a board on a prism.  While I think that there are better ways to design this, I think that this is something that others will also try and I having a hard time getting my head around the appropriate mate connection to use where the top of the prism meets the middle of the board.  Maybe there isn't one, but I'd be curious to know if anyone has a quick solution.  Thanks in advance.

I believe you can accomplish what you are saying using a revolute mate. The key is to define mate connectors at the appropriate locations (and orientations) on each part.

This document shows an example:

Thank you, Daniel.  I had tried something like this a while back with no success.  I find that sometimes identifying the exact mate point can be finicky and maybe that was my issue in the past.  Thanks again!
