Dynamic simulation, ball joints.

[richardWE24B]

Hi All,

New to Inventor and especially to assemblies and dynamic simulation.  I am trying to build a simple 'twist to steer' mechanism and I cannot get the ball joints to work to complete the assembly.  The last one always causes a conflict.    Initially I had the spherical joints as sub assemblies with the ball joint and tried placing them with conventional axis/axis constraints but the ball joint didn't work in the larger assembly.  I have separated the balls into the higher level assembly and this seems to do what I want except for the last joint.  Any pointers on where I am going wrong would be appreciated.

Richard.

An assembly requires parts.

I have never used Catia, but it appears to me that MCAD program uses part and assembly structure just like Inventor, SolidWorks and Creo.
