I was trying to learn the tutorial "Making Models using Solidworks". But, I got same error in the end. So, I downloaded the example zip file but still the error persisted. I really don't know if I had made some wrong alteration as I am new to Anybody.
Other example that I tried earlier was that of Padel. And it is working fine.
I'm sorry that the model failed - I found a bug in it and here is a fixed version:
The initial position of the human needed to be moved closer to the actual position and there was a reference frame that was misaligned at the feet.
You should be able to run this version now. FitnessMachine_With_Human.zip (268.9 KB)
Thanks a lot for reporting the error, we appreciate it!
