Creating Surfaces
In AXEL, you can use preset surfaces or generate 3D surfaces from 2D curves.
Preset surfaces, also known as primitives, are standard geometric shapes, such as spheres, rectangles, cones, and cylinders. You can resize, move, and rotate them, or manipulate points on the surfaces to create different shapes. See Creating spheres, cubes, cylinders, cones, planes .
The methods for generating 3D objects from curves mimic real-life methods:
- Creating a polygon surface is like weaving, where you make a contour shape, then weave a mesh over the contour. See Creating a polygon surface.
- Revolution is similar to a woodworker's lathe, where a piece of wood is set spinning around an axis and then a sharp cutting surface carves out a shape, like a baseball bat. See Creating a revolution surface.
- Extrusion is a common industrial process where a mold is created in the shape of the desired part and then the material is pushed (or extruded) through. The result is like the original shape with adjustable depth. See Creating extrusion surfaces.
When you create a revolution or an extrusion, a relation is maintained between the curve and the surface, so that when you edit the curve, the surface is updated to reflect those changes. When you create a polygon surface, it is independent from the original curve.
