Topics in this section

• Overview of Creating 3D Solids and Surfaces
• Create 3D Solid Primitives

  You can create the basic solid shapes of box, cone, cylinder, sphere, torus, wedge, and pyramid. These shapes are called solid primitives.

• Create a Polysolid

  A polysolid is drawn the same way you draw a polyline. By default, a polysolid always has a rectangular profile. You can specify the height and width of the profile. Use POLYSOLID to create walls in your model.

• Create Solids and Surfaces from Lines and Curves

  You can create solids and surfaces from existing lines and curves. You can use these objects to define both the profile and path for the solid or surface.

• Create Solids and Surfaces from Objects

  You can create surfaces from existing objects in your drawing.

• Create Solids from Surfaces

  You can create a 3D solid from any surface type by thickening the surface.

• Create Composite Solids

  Composite solids are created from two or more individual solids through any of the following commands: UNION, SUBTRACT, and INTERSECT. (FILLET and CHAMFER also create composite solids.)

• Create Solids by Slicing

  You can create new solids by slicing existing ones. You can define the cutting plane a number of ways, including specifying points or selecting a surface or planar object.
