Hi Ray, after you create a loft through several curves the history function allows you to edit the points of the curves and the loft surface will automatically get updated with the loft recalculating. That can make it easier to control sculpted surface shaping.

That's probably the most common use for it in MOI.

I think the one in Shapr3D is a little different, I think they have the more traditional Mechanical CAD parametric feature based history where your model is made up of a feature tree with things like fillet radius values listed in the tree so you can modify those later on.
