Go to Draw > Wire Grid > Cylinder in the main menu to display the Draw dialog box for the Cylinder. There are three pages: Cylinder, Attributes and Materials.
The Cylinder page
In the Cylinder page the geometrical parameters for the Cylinder can be set, Fig. 1. There is a combo-box with two options: Curved segments and Straight segments. Choose Curved segments for an exact representation of the cylinder curvature. The Straight segments option is an approximation using linear wires.
The Cylinder is defined by giving the Base Point coordinates, Length, Radius and orientation angles, Theta and Phi. A cylinder is a surface which is defined uniquely by these parameters, as shown in Fig. 2.
Once the geometrical parameters in the Cylinder page have been set, the Attributes page can be chosen, where the number of facets of the Cylinder can be entered. Refer to Wire Grid Attributes > to see other parameters that can be set in the Attributes page. Refer to Wire Materials > to see the parameters that can be set in the Materials page.
