Surface Modeler
Interface

Model curves and surfaces with smooth change of curvature

Create exact and steady b-spline curves and surfaces in AutoCAD with 3D polylines and networks of points. Produces high-quality curves and surfaces.

Model car surfaces, airplane, ships & more.

Surface Modeler is intended for modeling curves and surfaces of the high order of continuity with smooth change of curvature. With Surface Modeler you’ll be able to create first-class objects with curvilinear surfaces. Their quality is dependent on their geometric characteristics.

Surface Modeler is the tool of choice for modeling car surfaces, external contours of airplanes and ships, working surfaces of blades of compressor rotors, turbines and pumps and curvilinear architectural forms, art products, animated cartoons and advertisements.

Basic Features

Surface Modeler is an AutoCAD application which works in the AutoCAD environment. You can use AutoCAD commands to edit objects created with Surface Modeler (with b-spline curves and high degree surfaces being an exception).

B-spline curves created with Surface Modeler can be converted into NURBS format used by AutoCAD and further edited by means of AutoCAD SPLINE command or passed to another CAD system.

Quality of modeling curve

Surface Modeler ensures the quality of a curve by means of controlling its radius of curvature. The locus of centers of curvature is called the evolute. It exactly characterizes the quality of the curve, that is:

These geometric characteristics determine the aero-hydro-dynamic characteristics of objects that undergo high-speed interaction with the environment. Besides functional characteristics, the geometry of an object also defines its aesthetic properties (e.g. in the automobile industry).

With Surface Modeler you can also perform the analysis of curvature using the so-called “epure” of the curvature.
