How to move constrained point?

josh_mccullough080

I'm creating a ratchet, and need to extend all of the "teeth", each of which are constrained to be equal (shown here by small green line). I want to extend the dimensioned tooth downward as shown by the red circle/arrow. However, I cannot move the point. When I try, it just disconnects the leftward line from the downward line (red arrow).





Here's what happens when I change the dimension:



I'm new here, so any advice on how to properly constrain this thing is welcomed!

Maybe you would find this approach something you would want to use





And because Onshape is a PARAMETRIC CAD program, it makes it easy to modify

@steve_shubin very cool! I will give that a try.

Update: Got it with your excellent visual guide -- thank you!

Hello. From Josh's images and description, it's apparent that the 'left line' does not move with the shorter, more vertical line when that line's dimension is changed is because the end points of those two lines are not coincident; they are not connected to each other. Adding a coincident constraint to the end points would rectify that. - Scotty
