spin panel

Location: 2D and 3D pages

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

HM_Panels_bmp00303

Nodes are selected.

HM_Panels_bmp00304

The base node is selected.

HM_Panels_bmp00305

The surface is created.

Spin lines to create a surface

HM_Panels_bmp00306

Nodes are selected.

HM_Panels_bmp00307

The base point is selected.

HM_Panels_bmp00308

The surface is created.

Spin elements to create a surface

HM_Panels_bmp00309

Elements are selected.

HM_Panels_bmp00313

The base point is selected.

HM_Panels_bmp00311

The surface is created.

Spin a group of elements to create a surface

HM_Panels_bmp00312

Elements are selected.

HM_Panels_bmp00310

The base point is selected.

HM_Panels_bmp00314

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

HM_Panels_bmp00315

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.

Panel Inputs

Input	Action
elems selector	Pick the elements you want to spin.
N1, N2, N3, B	Specify a plane. The elements are spun about the normal of the plane.
angle	The angle through which to spin the elements.
on spin	Enter the number of elements you want to generate along the path of the spin.
bias style	Select linear, exponential or bellcuve
bias intensity

The following action buttons appear throughout the subpanels:

Input	Action
spin +	Creates the surfaces in the direction specified.
spin -	Creates the surfaces in the opposite direction
reject	Reverts the most recent changes.
return	Exits the panel.
