Revolute Mate (Probably very simple)

steven_phang

Hi, I'm new to all of this...
Im trying to make a box with a rotating hindged lid on top with two parts: the box and the lid
I tried to put a revolute mate on it to see how it opened and it worked, but it rotates a full 360 degrees where the top of the lid will phase through the box. I wanted to test if the lid had enough clearence to swing open, but I can't if it just goes through the box anyway.

Is there a way to make it so it stops rotating if the top of the lid hits the box so it does not go through?
I appreciate any help I can get.
Thanks!

Ok, let's take an example like this one:
https://cad.onshape.com/documents/e4743eb6578279537d5858f3/w/3338eb3f83d325dbe4a85ef8/e/64816f8997d2529609467250

1- You can create a few named positions in the assembly
You can edit the limits of the revolute mate to create easily that named positions
2- Edit in context one of the parts (the fix or grouped one)
3- Transform and copy in place the other part (The part that can rotate) at a specific angle defined in a named positions
4- You can use a FeatureScript like "Find overlaps v2" included in this example to get the overlaps between the 2 parts at that specific angle

Now you can test if there are overlaps with another angle (other named position) 
1- Change the angle (select other named position) in the assembly
2- Go to the Part Studio and update the context
3- Then you can check if the parts overlaps

It is no easy, and it is no very clean and fast... but it works

Try doing a section view in the assembly
It will show overlaps in red

The FeatureScript Find overlaps was created by @Jake_Rosenfeld and improved by @mbartlett21

Thanks for the help! I'll post back if it works

Of course ;-) but overlaps can exists even if you don't see it
