Difficulty defining constraints

[ptc-4964368]

I am assembling patrs for simulation and i am trying to denine contact constraints betweens two parts. i would like the part (like golf club shap to push rod as the golf shape part moves along the pin axis. but it would not allow me to select the surfaces using contact command icon. i attached a picture of the assembly to this note. please i need help.

Hi Solim,

Hmmm, interesting. Is there any chance that you could attach the files that you're working on? I'll see if I can figure it out and get back to you on how it goes.

Thanks!
