The errors in the MapleSim model are due to the fact that the DefiningHardPoints.mw file doesn't work and so there are some problem with the kinematic becuase i would need to fix other parameters, but don't care about theme beacause I need only to fix the problem with the DefiningHardPoints Maple document. So starting from a new file what I did is:
1) in MapleSim: edit>Store Parameter Set> I called it "new"
2) in DefiningHardPoints.mw maple document: changing, in the first row of the code, the word "Symbolic" with "new" (in this way i'm able to "upload" the new parameter set I want to work on) as can be seen from the picture below.
At this point there is the error message and so the document stops and doesn't substitute the parameters.
This is the model edit as written above:
