To Create a Cylindrical Surface
1. Restyle > Analytical Surface > Cylinder. The Cylinder dialog box opens.
2. Click the required check boxes for defining the surface:
Full—Creates a complete cylinder of 360 degrees.
Domain—Uses the selected domain for creating the surface.
3. Select the references for the cylindrical 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 cylinder 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 you select an axis for direction reference, it is used as an axis of the cylinder. The orientation of the surface depends upon the directional reference.
4. In the Diameter box, type a value for the diameter of the cylinder.
5. Under Direction angular dimensions, change the angle that the cylindrical surface makes with the direction vectors to rotate the surface in the required direction.
6. Click OK.
