Spin Panel

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.

Location: 2D and 3D pages

Spin Geoms Subpanel

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.
Option Action
node list / lines selector Select the nodes/lines to spin.
N1, N2, N3, B Select a plane.

The selected nodes are spun about the normal of the plane.
angle Specify the angle through which to spin the nodes.
meshing options
mesh, keep surf
Create a surface from the selected entities and generate a mesh on the created surface.
The created surface is retained along with the mesh.
mesh, dele surf
Create a surface from the selected entities and generate a mesh on the created surface.
The created surface is deleted and only the corresponding mesh is retained.
mesh w/o surf
Create a mesh between the selected entities using linear interpolation without creating a surface.
surface only
Create a surface from selected entities, but do not generate a mesh.
Use the resulting surface to perform any desired geometry cleanup functions or automeshing.

Spin Elems Subpanel

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.
Option Action
elems selector Select the elements to spin.
N1, N2, N3, B Select a plane.

The elements are spun about the normal of the plane.
angle Specify the angle through which to spin the elements.
on spin Specify the number of elements to generate along the path of the spin.
bias style Select a bias style.
bias intensity Specify a bias intensity.

Command Buttons

Option Action
spin + Create the surfaces in the direction specified.
spin - Create the surfaces in the opposite direction.
reject Revert the most recent changes.
return Exit the panel.
