20.3.2 Creating an object that has Dynamic Geometry

If you use one of the following tools to create an object, it will have Dynamic Geometry that can be editted:

· Extrusion
· Sweep
· Double Sweep
· Ruled Surfaces
· Coons and Gordon Surfaces
· Smoothing

Depending on how an object has been made, it can have up to four finishing levels:

Finishing level and illustration	Description
1	Circle, Polyline…
Smoothed structure 2	Smoothing, interpolation, approximated structure. The interpolated Curve tool creates smoothed structures directly.
3	Object made from a smoothed structure or not. The construction can be made from one of the following tools: Extrusion Sweep Double Sweep Ruled Surfaces Coons and Gordon Surfaces The “3D Primitives” and “Text” tools create rough objects directly, but they don’t have a finishing level lower than 3.
Smoothed object 4	Smoothed rough object

You can choose to work on any finishing level of an object. The higher levels will be affected by modifications to the lower ones.

In the object’s “Information” dialog, a button allows you to delete the Dynamic Geometry of the current object: “Convert to Mesh” (see User Manual/ Modeling help tools/ Control Panel/ Information).
