Function
- Move or copy nodes symmetrically with respect to a particular Mirroring Plane.
Call
From the main menu, select [Node/Element] tab > [General] group > [Mirror] > [Mirror Node]
Input
Mirror Nodes dialog box
Click 
to the right of Mirror 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 on option to specify a desired number.
Mode
Copy : To copy nodes
Move : To move nodes
Reflection
Assign the mirroring plane
y-z plane : Mirroring plane is parallel to the y-z plane
x : x coordinate of the mirroring plane
x-y plane : Mirroring plane is parallel to the x-y plane
z : z coordinate of the mirroring plane
z-x plane : Mirroring plane is parallel to the z-x plane
y : y coordinate of the mirroring plane
Plane defined by 3 pts. : Mirroring plane is an arbitrary plane
x1, y1, z1 : x, y, z coordinates of the 1st point defining the mirroring plane
x2, y2, z2 : x, y, z coordinates of the 2nd point defining the mirroring plane
x3, y3, z3 : x, y, z coordinates of the last point defining the mirroring plane
The coordinates of the three points may be directly typed in on the keyboard. Alternatively, click the relevant entry field and the desired point in the working window to enter the x, y, z coordinates.
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 attribute 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.
