1.Select the spin elems subpanel.
2.Indicate the elements you want to spin:
Pick the elements on your model.

or

Click elems and choose from the extended entity selection menu.

3.Use the plane and vector collector to specify a plane.

The elements are spun about the normal of the plane.

4.Select base and select a base point.

5.Select angle = and specify an angle through which to spin the elements.
6.Select on spin = and enter the number of elements you want to generate along the path of the spin.
7.Click bias style: and select linear, exponential or bellcuve.
8.Click the data entry field after bias intensity = and enter the desired value.

For more information on the biasing options, refer to the Element Biasing section in the Automatic Mesh Generation chapter of the User’s Manual.

9.Click spin+.
10.To generate the elements in the opposite direction, click spin-.

The elements in this illustration were created by using spin +, with a negative biasing value.

The elements in this illustration were created without element biasing.

Undo

Select reject immediately after you create the surface and/or mesh or elements.  To reinstate the rejected entities, select spin+ or spin- again without changing any of the input data.  The input nodes and/or lines or elements used to create the entities are restored provided that no data is selected after the surface and/or mesh or elements are created.

 

Comments

You can use a line segment.

The order in which the nodes are selected determines the connectivity of the mesh generated.

When one-dimensional elements are spun, two-dimensional elements are generated.  When two-dimensional elements are spun, three-dimensional elements are generated.  The spin operator ignores three-dimensional elements.
