Use the Rotate panel to rotate entities around an axis in space. The axis of rotation can be selected in several different ways, and the entities rotated can include an entire model or only portions of it.

Notes

•	Do not use the Rotate panel to rotate a dummy. Doing so corrupts the tree structure and produces incorrect results when you reposition the dummy. Instead, use the Dummy panel.

•	To undo a rotation, simply rotate the entities in the opposite direction without changing the axis or angle: one click of rotate – undoes one click of rotate + and vice-versa.

•	Local coordinate system axes can be specified using the vector selection option.

•	When rotating components, all of the geometry (lines, surfaces, points) and elements (nodes) contained in the selected component are automatically rotated.

•	Rotating nodes or elements does not change connectivity or continuity of a mesh.

•	Rotating only some of the nodes in an element may distort the element.

•	Rotating surfaces may affect edge topology (shared edges may become free edges).

•

Rotating elements or surfaces independently will break any associations between the surfaces and the elements (nodes) created on them. Rotating in the opposite direction as described above for "undoing" a rotation will not restore these associations. Lost associations can be restored via the Node Edit panel.

Subpanels and Inputs

There are no subpanels on the Rotate panel. All inputs and command buttons are located on the main panel.

Panel Inputs

Input

Action

entity selector

Used to select entities for translation. Valid entity types include nodes, elements, lines, components, surfaces, systems, groups, points, blocks, multibodies, ellipsoids, multibody planes, solids, and connectors.

When you select nodes or elems, click the switch to change the selection mode.

nodes

Select individual nodes.

faces_edges_nodes

faces

Select all of the nodes on 2D and 3D faces.

If there are discontinuities on a 2D face, then only the nodes inbetween the discontinuities will be selected.

faces_edges_faces_nodes

2D faces ext

Select all of the nodes on a 2D face that contain discontinuities.

faces_edges_2d_face_ext_nodes

loops

Select all of the nodes on continuous free edges that make a closed loop simultaneously, such as the perimeter of a hole.

Only valid for SHELL elements.

faces_edges_loops_nodes

free edges

Select all of the nodes on free edges of elements.

If there are discontinuities on an edge, then only the nodes on the free edges inbetween the discontinuities will be selected.

Only valid for SHELL elements.

faces_edges_free_edges_nodes

free edges ext

Select all of the nodes on free edges of elements that contain discontinuities.

Only valid for SHELL elements.

faces_edges_free_edges_ext_nodes

edges

Select all of the nodes on free edges or shared edges (butt joints, L/corner joints, and T-joints) of elements.

If there are discontinuities on an edge, then only the nodes on the edge inbetween the discontinuities will be selected.

Only valid for SHELL elements.

faces_edges_edges_nodes

edges ext

Select all of the nodes on free edges or shared edges (butt joints, L/corner joints, and T-joints) of elements that contain discontinuities.

Only valid for SHELL elements.

faces_edges_edges_ext_nodes

elems

Select individual elements, or select all of the elements contained by a component or on a surface.

faces_edges_entities

faces

Select all of the elements on 2D and 3D faces.

If there are discontinuities on a 2D face, then only the elements inbetween the discontinuities will be selected.

faces_edges_faces

2D faces ext

Select all of the elements on a 2D face that contain discontinuities.

faces_edges_2d_faces_ext

plane selector

Used to define the axis of rotation.

•	The axis chosen may be one of the global coordinate system axes (x-axis, y-axis, or z-axis), or a vector.

•	When using the vector option, you can specify the vector from a coordinate system (global or local) or a vector entity created via the Vectors panel.

•	When using the N1, N2, N3 option you can either define a vector using two nodes (N1 and N2) or a plane (N1, N2, N3) in which case the positive direction is defined by the normal to the plane using the right-hand rule.

•	A base node is required because it defines the location of the axis of rotation. If you do not specify one while using the N1, N2, N3 method, N1 is used as the base node.

angle

Type the number of degrees (positive or negative) that you want the selected entities to rotate each time you click the rotate + or rotate - button. Click this field twice to access the built-in calculator.

face angle / Individual selection

Face angle

The face angle is the angle between the normal of facets that share an element edge. A facet can either be a shell element itself, or one of the faces of a solid element. The normal of triangular facets is that of the plane defined three corner vertices. Whereas, the normal of quadrilateral facets is calculated by taking the cross-product between its two diagonals. This special treatment for quadrilaterals is because a warped shape does not lie completely on a plane.

Only available when the entity selector is set to nodes or elems and the selection mode is set to faces, 2d faces ext, free edges, free edges ext, edges, or edges ext.

Individual Selection

Select individual elements on a face or select individual free/shared edges of elements.

Only available when the entity selector is set to nodes or elems and the selection mode is set to faces, free edges, or edges.

edge angle

Splits edges that belong to a given face.

When the edge angle is 180 degrees, edges are the continuous boundaries of faces. For smaller values, these same boundary edges are split wherever the angle between segments exceeds the specified value. A segment is the edge of a single element.

Only available when the entity selector is set to nodes and the selection mode is set to free edges, free edges ext, edges, or edges ext.

Command Buttons

The following action buttons appear:

Button	Action
rotate +	Rotates the selected entities in the positive direction of the rotation axis by the specified angle. Repeated clicks are cumulative.
rotate -	Rotates the selected entities in the negative direction of the rotation axis by the specified angle. Repeated clicks are cumulative.
return	Exits the panel.
