Use the Spin panel to create a surface and/or mesh or elements by spinning a series of nodes, a line or lines, or a group of elements about a vector to create a circular structure.
Examples
Spin nodes to create a surface

Nodes are selected.
|

The base node is selected.
|

The surface is created.
|
Spin lines to create a surface

Nodes are selected.
|

The base point is selected.
|

The surface is created.
|
Spin elements to create a surface

Elements are selected.
|

The base point is selected.
|

The surface is created.
|
Spin a group of elements to create a surface

Elements are selected.
|

The base point is selected.
|

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.

Subpanels and Inputs
The Spin panel contains the following subpanels and command buttons:
Use the Spin Geoms subpanel to create a surface and/or mesh or elements by spinning a series of nodes, a line, or lines about the normal of a user-defined plane.
Panel Inputs
Input
|
Action
|
node list / lines selector
|
Pick the nodes/lines you want to spin.
|
N1, N2, N3, B
|
Specify a plane.
The selected nodes are spun about the normal of the plane.
|
angle
|
The angle through which to spin the nodes.
|
meshing options
|
• | mesh, keep surf: creates a surface from the selected entities and then generates a mesh on the created surface. The created surface is retained along with the mesh. |
• | mesh, dele surf: creates a surface from the selected entities and then generates a mesh on the created surface. The created surface is then deleted and only the corresponding mesh is retained. |
• | mesh w/o surf: This option creates a mesh between the selected entities using linear interpolation without creating a surface. |
• | surface only: creates a surface from selected entities, but does not create a mesh. You can use the resulting surface to perform any desired geometry cleanup functions or automeshing. |
|
|
Use the Spin Elems subpanel to create a surface and/or mesh or elements by spinning a group of elements about the normal of a user-defined plane.
