Hello i try to simulate an assembly, different parts act like hinges so i tried adding a pin connection.

I select the cilindrical face of component 1 and the cilindrical face of component 2, selected the material.

But when i click on the green "ok" button nothing happens and i get a message please enter a value between 0 and 10000000000 for the "alpha".

Is this a bug in the program or am i doing something wrong?

Thanks
