How to Constrain Surface of a Part in Assembly to be Free to Move in all Directions Except One Direction?

[danderson]

Hi,

I have a large assembly where I have used a simplified rep to exclude all components except one component and all of it's fasteners (solid models).

The fasteners have preload assigned.

I now want to add a simulate feature / constraint to the base of the component to simulate the contact the surface of the component would partially see in the component assembly.

All I'm trying to do is check to see if the component has proper constraints to the fasteners with out running the complete large assembly.

How would one constrain one surface of a part so it's free to move in all directions except one.  example all rotation axis free to move and translate except no negative x translation?

Thanks,

Don Anderson

Hi,

PTC's response was to use springs with different stiffness in two directions.

I have created a new enhancement request. Click link below for enhancement request unless someone has another Idea of how to approach this?
