Design 3D extrusions with this unique visual tool!
Extrusion Editor, a visual plug-in for ParallelGraphics' VrmlPad, offers you an effective method for creating and editing extrusion models.

Extrusion Editor allows you to create extrusion models from scratch or edit existing models. It offers you a variety of drawing algorithms for the spine and cross-section path which include:
Drawing a series of connected vertices one by one

Drawing Bezier curves (spline curves)

The use of pre-defined forms (rectangle, diamond, octagon, triangle, oval, etc)

The editing abilities allow you to:
Move, scale, flip and rotate the spine and cross-section

Add/remove the vertices

Control the smoothness of the curves

All changes are immediately displayed in the 3D window.
