Mechanism Sliding Fit Interaction

Hi all,

 

This is my first post on this community forum, so I apologize in advance if I'm missing anything!

 

I am working on an assembly where I have two parts that fit together with a small gap of 0.05mm. I am attempting to use the Mechanisms in Creo (which are apparently tedious to use in Creo compared to SW). I am using a 'Slider' constraint between two said components. I have attached a zip with part and assembly files.

 

The problem I am having is that despite with a 0.05mm gap, it seems like Creo thinks the parts are touching when they are not. What I mean by this is in the image below, you would think the surface highlighted in green would be flush with the one next to it. However, when I drag the components together, this is as close together as they can go!

I have no clue why this is happening. I assume it's probably some setting that I did not know to change. Any help would be appreciated!

 

I have tried changing the diameters around, and I've found that making the gap between the two larger results in me being able to drag the components closer to be considered flush with one another.

 

Thank you!

Hello @JiffiPop , @kdirth & @MartinHanak 

 

Just illustrating what I documented above in little movie below for future reference if needed, and to hopefully grant a better understanding of what I meant.

The second part moves fine for me in the assembly supplied.  The only thing that I see missing is setting some limits on the movement and a regen value if desired.

 

I am not sure what you are expecting.  In the slider mechanism connection, the translation constraint does not snap to 0.  You have to enter the desired position and set the movement limits.

There is always more to learn.

    I did leave limits and regen value out for the example. Below I have uploaded a video to clearly explain my issue. My question is why will the parts not drag together so they touch?
