Function
- Move or copy existing nodes by rotating about a particular axis.
Call
From the main menu, select [Node/Element] tab > [General] group > [Rotate] > [Rotate Node]
Input
Rotate Nodes dialog box
Click 
to the right of Rotate Nodes
Display the Node Table
Start Node Number
Enter a starting node number for the newly created nodes. This number is auto-set to the largest node number in use +1. To modify this item, click and select an option to specify a desired number.
Mode
Copy : To copy nodes
Move : To move nodes
Rotation
Equal Angle : To copy nodes at an equal angle of rotation
Number of Times : Number of repetitions
Angle of Rotation : Angle of rotation for copying
> 0 : Copy (or move) about the rotation axis using the right hand rule
< 0 : Copy (or move) about the rotation axis opposite to the right hand rule
Unequal Angle : To copy nodes by rotation at unequal angles
Angle : Unequal angles for rotation
(Ex : 20,10, 3@30, 15 = 20, 10, 30, 30, 30, 15)
Distances(radial)/Distance(axial)
Specify distances in radial and rotational axis directions when copying nodes by rotating them by a given rotational angle (spiral or helical curve shape)
Axis of Rotation : Selection field to assign the rotational axis
About x-axis : UCS x-axis
About y-axis : UCS y-axis
About z-axis : UCS z-axis
About axis defined by 2 pts. : A line connecting two points defining the axis of rotation
1st point
Enter the coordinates of a point when About x, y, z axis is selected
Enter the coordinates of the 1st point when About axis defined by 2 pts. is selected
2nd point
Enter the coordinates of the 2nd point when About axis defined by 2 pts. is selected.
Merge Duplicate Nodes
Merge overlapping nodes to single nodes if new nodes coincide with existing nodes. Click to modify the Merging Tolerance.
Copy Node Attributes
Select the option whether to copy the attributes (nodal boundary conditions, nodal concentrated loads, rigid link, elastic link, etc.) to the nodes being copied. Click to assign desired attributes selectively.
Intersect Frame Elements
Select the option whether to divide the existing line (beam & truss) elements at the newly created nodes that intersect the elements. Click to modify Intersecting Tolerance.
