Creating and Modifying 3D Entities

Wireframe models consist of linear edges and curves that represent the edges of 3D entities. You create them with standard draw commands to draw Lines, Arcs, Circles, PolyLines, or Ellipses, for example.

Surface models consist of entities with edges and surfaces between those edges. You can create surface models by using specific 3D entity-creation commands.

• The commands to create surface models are discussed in the 3D Meshes section.
• The commands to modify entities in 3D space are discussed in the 3D Operations section.

To view, shade, and render models, refer to 3D Viewing.
