Rotate a node, element or mesh set about the rotation axis to move/copy. It is useful for continuously generating a mesh that forms a certain angle.

Select the node, element or mesh set to rotate move (or copy) and define the revolution axis.

Rotation Axis

Select the move/copy revolution axis with respect to the GCS or for the 2 points vector function, input the start and end point coordinates of the direction vector. It is useful when setting the reference axis in an arbitrary direction.

When using the GCS, use the [Locate] option to set the rotation axis position using its coordinates. The rotation axis is moved to the specified coordinate position and the node is rotated and moved/copied about this axis.

For the 2 points vector function, select (deselect) a particular coordinate axis and select only the directional comp1nt of a vector defined by a start and end point.

Methodology

Specify the rotation angle and rotation copy angle. A uniform angle or arbitrarily set non-uniform angle can be used to rotate and move/copy.

[Move]

Directly input the rotation angle.

[Copy (Uniform)]

Set the rotation angle and number of repetitions. Input a negative to rotate in the opposite direction to the set direction.

[Copy (Non-uniform)]

The angle can be listed using a comma (,) or as number@angle for continuously repeating angles.

For example, entering 10@30 continuously creates 10 elements that are rotated 30 degrees from the previous element and entering 20,30,40 creates 3 elements, each rotated and moved/copied by 20 degrees, 30 degrees and 40 degrees.

Copy Prestress for 1D Elements

If the anchor is modeled as a 1D element and the prestress load is entered, the load information is also copied when copying the anchor.
