Rotate Nodes

 

 

 

Move or copy existing nodes by rotating about a particular axis.

 

 

 

From the Main Menu select Node/Element > Nodes > Rotate.

 

 

 

 

 

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

 

Distance (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, 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.
