Rotation

You can rotate structure nodes or elements, using either method:

To define the rotation, set the main parameters in the following fields of the Rotation dialog:

You define the values for the rotation axis coordinates and the rotation angle in the following fields:

After you have defined the rotation angle graphically, Robot rotates the selected nodes or elements; or if no objects have been selected, click Select in the context menu to select them. Robot remains in the Rotation mode until the next command is selected or the <Esc> key is pressed.

If you manually define the rotation axis and angle in the Rotation dialog, clicking Execute completes the action.

Note: You cannot rotate structure elements or nodes until you select them.

After you select the Grid or Auto cursor mode, the co-ordinates of the points describing the symmetry axis are displayed in the Axis beginning and Axis end fields. If the Node cursor mode is selected, the numbers of nodes defining the symmetry axis are displayed in the Axis beginning and Axis end fields. The display in the Rotation axis field depends on the cursor mode:

You can define the rotation axis using either method:

Note: When entering the coordinates for the beginning and end of the axis in the Rotation dialog, the dialog is opened for either a plane or space structure view. When the 2D view is selected, field descriptions are coherent with the plane set (that is, ZX plane), and the number of coordinates displayed in these fields is limited to 2.
