I'm trying to create 3d contacts with curves, created with the spline tool in sketch/extrude. Is there other ways to create curves that work with 3d contacts? I'm using Creo 7.0, so would that be available in newer versions? is there a different way to get the same properties of the 3d contact tool?
Any help is appreciated.
Solved! Go to Solution.
You should look at the other mechanism connection types. i.e. cam/follower or slot. Friction is supported by these other connection types.
For 2D kinematic analysis/synthesis there are other specialized tools that will support a faster development cycle of the geometry.
Short answer is no.
Valid 3D contact references are as follows:
spherical, cylindrical, or planar surface, or a vertex.
It may be possible to create a valid construction reference driven by a curve that would work but you would have to provide details of exactly what you need to do.
See reference info here current for Creo 9:
I'm creating a sliding latch mechanism, you slide it forward and back and it locks in place; forward again and it comes unlatched.
It requires curves to minimise friction, and I need to use 3d contacts to get close to a final product that would work with my manufacturing materials in real life. I can do it without curves, but it would entail using a lot of ellipses and circles, which will not have the same ease of adjustment nor will it be an efficient system.
edit: oops, can't even use ellipses, I guess I'm going to be learning fusion360
the PNG below is the general/crude idea of the mechanism.

tried cam/follower or slot, i don't get the needed capabilities. "other specialized tools" do you have any recommendation, in todays age usually the kinematic software is built into the cad programs.
This is one option but certainly not the only one.
