The Add Objects Cylinder tool inserts a Cylinder primitive in the Working-Volume at the location of the 3D Cursor.
Cylinder primitives can also be generated with exact dimensions or drawn interactively using the Build > Build Primitives menu.
The Build Primitives Cylinder Tab page enables the generation of Cylindrical models by a specified dimension.
Type in the desired length, radius, number of sides, and Working-Volume center, then press the Make button.
You can also interactively generate a Cylindrical primitive by dragging out a bounding box in any of the Working-Volume' TOP, FRONT, or SIDE views. The specified Cylinder will fill the space of the bounding box. Note that the Auto checkbox must be checked to interactively draw primitives.
