Creating Cylindrical Surfaces

This task shows how to create a cylinder by extruding a circle along a given direction.

Open the Cylinder1.CATPart document.

1. Click Cylinder .

   The Cylinder Surface Definition dialog box appears.

2. Select the Point that gives the center of the circle to be extruded and specify the desired Direction of the cylinder axis.

   You can select a line to take its orientation as the direction or a plane to take its normal as direction. You can also specify the direction by means of X, Y, Z vector components by using the contextual menu on the Direction area.

3. Select the Radius of the cylinder.

4. Enter values or use the graphic manipulators to define the start and end limits of the extrusion.

5. Click Reverse Direction or the red arrow in the 3D geometry to display the direction of the cylinder on the other side of the selected point.

6. Click OK to create the surface.

   The surface (identified as Cylinder.xxx) is added to the specification tree.
