Overview of Creating 3D
Solids and Surfaces
objects often start as one of several basic shapes, or primitives,
that you can then modify and recombine. A 3D solid or surface can
also be the result of extruding a 2D shape to follow a specified
path in 3D space.
About Solid Primitives
You can create several basic 3D shapes,
known as solid primitives: boxes, cones, cylinders,
spheres, wedges, pyramids, and tori (donuts).
By combining primitive
shapes, you can create more complex solids. For example, you can
join two solids, subtract one from the other, or create a shape
based on the intersection of their volumes.
About Solids Based on Other
You can also create 3D
solids and surfaces from existing objects.
The following methods
- Sweep. Extends
a 2D object along a path.
- Extrusion. Extends
the shape of a 2D object in a perpendicular direction into 3D space.
- Revolve. Sweeps
a 2D object around an axis.
- Loft. Extends
the contours of a shape between one or more open or closed objects.
- Slice. Divides
a solid object into two separate 3D objects.
- Conversion. Converts
mesh objects and planar objects with thickness into solids and surfaces.
