Inventor to Simulink Proper work

Hello. I just export inventor model which is almost fixed.

I want to exported model with working condtion that means working wheel.

Since I'm not good at simulink multibody, I don't know how to fix this.

everything should be each point, but connected.

the most important part is wheel and wheel actuation(steer, rotation).

other things should be just connected.

this block diagram seems bad and may not work. -> all parts are connected with rigid transform which is wrong i think..

Is there anyone who can tell me how to fix this diagram?

i'll add my file so that you can help me easily.

Hi - it looks like your CAD model did not have any mates defined. Mates in the CAD system need to be defined in order for the export to produce joints. A list of how mates convert to joints is shown here:

In your model, you can add the joints directly to the block diagram. Here is an example:

The only other thing you have to make sure of is that the "B" and "F" ports are connected to frames that are at the right location and have the right orientation. You can use Rigid Transform blocks to create the right frames. The files you uploaded did not have the CAD files, so I cannot show you exactly what needs to be done, but I think you can figure it out if you have the CAD model already.
