Create a new node or create a set of nodes by copying the node simultaneously.
From the Main
Menu select Model > Nodes > Create Nodes.
Select Geometry
> Nodes > Create in the Menu tab of the Tree Menu.
Click Create Nodes in the Icon Menu.
Shortcut key:
[Ctrl]+[Alt]+1
Click to the right of Create 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.
Coordinates (x,y,z)
Enter the coordinates of the node by the
following two methods.
1.
Type in directly the x, y, z coordinates relative to the UCS.
2.
Click the coordinates entry field and the desired position in the working
window. The position coordinates are displayed in the Status Bar at the
bottom of the screen for reference.
It may be convenient to create nodes in conjunction
with Point Grid (or Line Grid) and Grid Snap.
Copy
Copy the node created by the above procedure
to simultaneously create additional nodes at an equal spacing.
Number
of Times: Number of times to copy
Distances (dx,dy,dz): Copy spacing in each coordinate
axis direction
In order to enter the copy spacing, type
in the entry field directly, or click the copy spacing entry field and
the copy distances in the working window.
Merge Duplicate Nodes
Merge overlapping nodes to single nodes if
new nodes coincide with existing nodes. Click to modify
the Merging Tolerance if necessary.
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 the Intersecting Tolerance
if necessary.
