10.4 Dynamic Geometry

The tools that generate surfaces from curves (Extrusion, Sweep, ...) can now “retain” the initial curves and also remember how the wireframe was generated.

This allows you to edit a surface—not from the surface wireframe—but from the construction curves, which become the control curves of the surface. The surface is automatically regenerated when you edit the curves (like NURBS control polygons).

The surface smoothing is now dynamic, since it is regenerated at each “initial” surface or curve manipulation.

The interpolated or smoothed polyline curves also retain the originating curve.

Dynamic Geometry properties are stackable and create control levels. You can choose to work on one of the object finishing levels .

Original object:	Transformed object:
The original object is a smoothed polyline.	We transform the object by moving a point of the construction polyline. The smoothed polyline is affected by this transformation.

Original object:	Transformed object:
The original object has been generated by extruding a circle (polyhedral) along a path (polyline). The result has been smoothed	We transform the object by moving some points of the construction polyline. The rough object (not smoothed) and the smoothed object are affectedy by this transformation.
