,`RBOT`

`RTOP`

Radii of the bottom and top faces of the cone. A value of zero or blank for either

or`RBOT`

defines a degenerate face at the center axis (i.e., the vertex of the cone). The same value for both`RTOP`

and`RBOT`

defines a cylinder instead of a cone.`RTOP`

,`Z1`

`Z2`

Working plane Z coordinates of the cone. The smaller value is always associated with the bottom face.

,`THETA1`

`THETA2`

Starting and ending angles (either order) of the cone. Used for creating a conical sector. The sector begins at the algebraically smaller angle, extends in a positive angular direction, and ends at the larger angle. The starting angle defaults to 0° and the ending angle defaults to 360°. See the

*Modeling and Meshing Guide*for an illustration.

Defines a solid conical volume centered about the working plane origin.
The non-degenerate face (top or bottom) is parallel to the working plane
but not necessarily coplanar with (i.e., "on") the working plane. The cone
must have a spatial volume greater than zero. (i.e., this volume primitive
command cannot be used to create a degenerate volume as a means of creating
an area.) For a cone of 360°, top and bottom faces will be circular (each
area defined with four lines), and they will be connected with two areas (each
spanning 180°). See the **CON4** command for an alternate
way to create cones.
