Cylinder

Cylinder creates a tube specified as a radius around a center line. You can specify the dimensions of the cylinder either with a start and point and a radius, or with a point, a direction, length and radius. It has no caps on the ends so you may need to use a Cap surface to complete your design. Cylinders are exact surfaces and contain a seam where two edge boundaries meet. Be careful not to trim across the seam. Editing along the seam is fine.

To create a cylinder:

1. Select Construct tab > Surfaces panel > Primitives > Cylinder to display the Cylinder dialog.
2. Optionally enter a name in the Surface name field.
3. Select either Two points or Direction, length to specify the construction method.
4. If Two points is selected:
   1. Enter the coordinates of the start point in the Center fields, or click the Pick location button and select it in the graphics window.
   2. Enter the coordinates of the end point in the End point fields, or click the Pick location button and select it in the graphics window.
5. If Direction, length is selected.
   1. Enter the coordinates of the start point in the Center fields, or click the Pick location button and select it in the graphics window.
   2. Enter the X, Y and Z dimensions of a direction vector in the Direction fields.
   3. Enter the length of the cylinder in the Length field.
6. Enter the Radius of the cylinder.
7. Click Preview to display a preview of the surface in the graphics window.

Click OK.
