You can use the Cylinder Tool to create cylinders. When the Cylinder Tool is clicked, a "Primitives" window will appear in the same space as the Group List window. Use the X, Y and Z entrants to modify the cylinder's position and height. Use the radius entrant to modify the radius of the cylinder. Any changes made in the Primitives window will be previewed in the 3D Viewing Window by a transparent gray cylinder.
You can also use the controls on the previewed cylinder in the 3D Viewing Window to edit the cylinder. Press add when you are finished editing the cylinder to add it to your existing geometry.
