Note: A hemisphere is considered to be a Sphere object, and its Properties contain a Sphere page. For details, see Standard 3D Objects.

...

1. Select the center point of the hemisphere. The point will be created on the current workplane.
   
   
2. Click to size the hemisphere, or enter the radius in the Inspector Bar.
   
   The hemisphere is created on the side of the positive Z axis.

cify 2D Base:* Uses an existing 2D object as the base.

1. Select the 2D object. (You cannot use 2D objects that are contained within a group or block.)
   
   
2. Select a point to define the height, or enter the height in the Inspector Bar. The height is perpendicular to the workplane of the 2D object.
   
   You can also select a 2D open object. In this case, a partial-cone surface object will be created.
   
   You can also use a compound profile, open or closed, for the 2D base. (A compound profile is a series of connected lines and/or arcs.) Make sure Specify 2D Base and Use Compound Profile are both active, and select the compound profile.
   
   When the profile is selected, select Finish Selection of Profile.

   ify Object Height Base:* Creates an offset cone by using a specified point for the cone tip.
3. Create the circular base.
   
   
4. Select the point which is directly under the desired tip.
   
   
5. Select a third point to specify the cone height, or enter the height in the Inspector Bar. The top point is directly above the selected point.

   t Cone by Plane:* Creates a truncated cone by cutting off the tip.
6. Create a standard cone.
   
   
7. Move the mouse back toward the base to create the cut. You can also enter the height of cut in the Inspector Bar.

   ut Cone as Lofting:* Creates an inverted, truncated cone by using a scaling factor for the cone base.
8. Create a standard cone.
   
   
9. Move the mouse outward to create the top of the cone. You can also enter a scaling factor in the Inspector Bar.
