Question

Can assembly constraints function like SolidWorks mates

Using Creo 8.0.11.0 and having some trouble getting an assembly to come together the right way. Major part of my problem is how parts refuse to move to satisfy the constraints on them like how I'm used to the SolidWorks mates work. Is there a config/setting I can change to make it function more like SolidWorks in that way? The rollback on the assembly while using edit definition is a whole other challenge adding onto this.

Maybe explain what the problem is and we can actually help. There is no "make it solidworks" config option.

Using Creo like Solidworks is a recipe for a life of pain and anguish!

Otherwise, if you want it to work like solidworks, you should probably use solidworks...sorry.

To elaborate, I have an assembly that has multiple "moving" parts linked together with a couple pivot points and the constraints seem to refuse to line up with the coincident and oriented constraints in place. I'm trying to not have to manually rotate each part into its perfect angle so it will finally line up. The rollback while editing definitely does not help that process either. I'm used to how Solidwork's mating would move parts to try and satisfy the constraints placed on it, is there some setting to change to get remotely closer to that? Using Solidworks isn't an option.

Hi,

are you able to upload some "example" assembly?

The 2 bars on top are lined up on one end that moves up and down, meant to push/pull the bottom parts to make them swivel around the center hole that's not aligned, effectively like a large pair of scissors at the end

Hi,

showing picture is not enough. If you can, please upload Creo data.

I feel your pain.

The way I go about this is using mechanism constraints. 

When in the constraint menu, in the placement tab, connection type, choose General. Then use that to create the constraint you want.
Now the part is still movable and you can constrain it to whatever. This way you can constrain top down and down up.

You can also use the other connection types but those are such a hassle, I always use general. As long as you don't use user defined, it's like SolidWorks.

 

The only thing is you get a little icon next to your parts using this type of constraint. It looks like two rectangles. You can just ignore them.
