A fast way to make a parametric model into non-parametric and to remove all dependency, simply change the tree mode from History mode to History-Free
To me, "history-free" is quite preferrable for making a complex surface model. under this mode, i can delete and rebuild any curves/surfaces...
if the calculaton is complete, you can right-click on "result" on the tree, then select "open" to view the results.
you can refer to the general steps here
