The objects are added to the current project. They do not displace existing work. If the 3D view is empty the objects are drawn immediately and in blue. If the view has existing work you will be asked to confirm the addition of the object before it is drawn selected and in yellow (see opposite). The object can then be moved, resized, rotated, etc. --- with respect to the rest of the scene. It can also be deleted.
For the cone, cylinder, sphere and torus a Revolution Steps dialog box is automatically invoked before they are drawn. This allows you to enter the number of rotation steps to be used in generating these revolved solids --- also the number of latitude layers in the sphere and torus. Spheres are drawn either with flat or cone-shaped polar caps, depending on which radio button option is selected in the dialog box. Try it. The torus requires entry of major and minor radii via a dialog box.
All objects are drawn the same apparent size, regardless of the scale settings. In other words they are scaled to match the dimensions of the axes. Their size is easily altered with the grow, shrink and resize commands.
