To Create a Conical Surface
1. Click > > 
Cone. The Cone dialog box opens.
Cone. The Cone dialog box opens.2. Click the required check boxes for defining the surface:
◦ Full—Creates a complete cone of 360 degrees.
◦ Domain—Uses the selected domain for creating the surface.
3. Select the references for the conical surface.
◦ Coordinate system—Selects the coordinate system. This coordinate system is used as a reference for manipulating or moving the surface.
◦ Origin point—The center of the base circle of the cone is its origin. For analytical surfaces, if you want to define the origin point before the creation of the surface, you can only select datum points. After creating the surface, to modify the origin point, you can select any location on the facet for defining the origin point.
The surface is translated along its axis such that in the new position, the origin point of the surface and the facet point lie on the same plane that is normal to the axis.
Restyle displays the x-, y-, and z-coordinates of the origin point in the respective Origin point coordinates boxes. You can change these coordinates to move the origin point and the surface.
◦ Direction—Selects a datum plane or an axis as a directional reference where required. If an axis is selected for direction, it becomes the axis of the cone. The orientation of the surface depends upon the directional reference.
4. In the Diameter box, type a value for the circular base of the conical surface.
5. In the Draft angle box, type a value for the draft angle of the cone. You cannot specify a draft angle of more than 90 degrees.
6. In the Cone height box, type a value for the cone height.
7. Under Direction angular dimensions, change the angle that the conical surface makes with the direction vectors to rotate the surface in the required direction.
8. Click OK.
