You can create a surface of revolution, which is a three-dimensional polygon mesh that approximates the surface generated by rotating a two-dimensional profile around an axis. You select the two entities that define the profile and the axis. You also specify the starting angle and the number of degrees to revolve the profile.
Revolving the profile 360 degrees creates a closed three-dimensional mesh. The Number Of M-Direction Surfaces value determines the mesh density (the number of mesh segments) in the M-direction (around the axis of revolution). The N-Direction Mesh Density value determines the mesh density (the number of mesh segments) in the N-direction (along the axis of revolution).

TIP To control the density of the mesh, change the values for the Number Of M-Direction Surfaces and N-Direction Mesh Density. Choose Settings > Drawing Settings, and then click the 3D Settings tab. Under Change Settings For, select Surfaces. Under Surface Settings, change the Number Of M-Direction Surfaces and N-Direction Mesh Density values. Or on the Settings toolbar, use the Drawing Settings tool () to display that dialog box.
