As mentioned previously, cylindrical surfaces are extruded circles. To draw a cylindrical surface:
- Select the Circle tool. The cursor changes to a pencil with a circle.
- Click to place the center point of the circle.
- Move the mouse out from the center point to define the radius of your circle. As you do so, the radius value is displayed dynamically in the Measurements toolbar and can be specified by typing in a length value followed by pressing the Enter (Microsoft Windows) or Return (Mac OS X) key. You can also specify the segmentation for the circle in the Measurements toolbar.
- Click a second time to finish the circle.
- Select the Push/Pull tool. The cursor will change to a 3D rectangle with an up arrow.
- Click on the face
- Move the cursor up to create cylinder in the positive direction or move the cursor down to expand the cylinder in the negative direction.
- Click again when the cylinder has reached the desired size. The vertical surface is a cylindrical surface.
