How is AutoSolids parametric modeler different from traditional parametric modelers?
AutoSolids modeling system does not require the use of constraints to change geometry. Traditional parametric modelers typically require that constraints be applied to models to allow them to be changed. For instance, to change the height of an extrusion, a dimensional height constraint must first be applied to the extrusion, and then the value of the constraint is changed causing the geometry to change. AutoSolids automatically captures the exact parameters used to define the solid, and presents those parameters back to the user when the solid is picked for editing. With the same example, when the extrusion is picked for editing, a dialog is immediately presented that contains all of the extrusions inherent parameters(height, taper angle, extrusion direction), any or all of which can then be changed. The intermediate step of creating constraints is completely eliminated. And because there are no constraints, there is no need for such things as workpoints, workplanes, construction plan
