Function
- Move or copy nodes by projection on a particular line or surface.
Call
From the main menu, select [Node/Element] tab > [Node Detail] group > [Edit Nodes] > [Project]
Input
Project Nodes dialog box
Click 
to the right of Project 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
Projection Type
Select the geometric shape of a Projection Base onto which nodes are projected.
The types of projection base are as follows :
Project nodes on a line
Project nodes on a plane
Project nodes on a cylinder
Project nodes on a cone
Project nodes on a sphere
Project nodes on an ellipsoid
Project nodes on a parabolic plane
Project nodes on an element
Base Line Definition
Enter the data necessary to define a projection base as follows :
All the data can be directly typed in on the keyboard. Alternatively, click the relevant entry fields and the nodes (related data) defining the base in the working window.
Project nodes on a line
P1 : Coordinates of a point located on the Base Line
P2 : Coordinates of another point located on the Base Line
Project nodes on a plane
P1 : Coordinates of a point located on the Base Plane
P2 : Coordinates of another point located on the Base Plane
P3 : Coordinates of a 3rd point located on the Base Plane
Project nodes on a cylinder
P1 : Coordinates of a point located on the central axis of the Base Cylinder
P2 : Coordinates of another point located on the central axis of the Base Cylinder
Radius : Radius of the Base Cylinder
Project nodes on a cone
P1 : Coordinates of a point located on the central axis of the Base Cone
P2 : Coordinates of another point located on the central axis of the Base Cone
Radius 1 : Radius of the Base Cylinder at position P1
Radius 2 : Radius of the Base Cylinder at position P2
Project nodes on a sphere
Origin : Coordinates of the center of the Base Sphere
Radius : Radius of the Base Sphere
Project nodes on an ellipsoid
P1 : Coordinates of the center of the Ellipsoid's bottom surface
P2 : Coordinates of the top of the Base Ellipsoid
Radius : Radius of the circle at the bottom surface of the Base Ellipsoid
Project nodes on a parabolic plane
P1 : Coordinates of a point on the Parabolic Plane
P2 : Coordinates of a second point on the Parabolic Plane
P3 : Coordinates of a third point on the Parabolic Plane
Project nodes on an element
Element Number : Plate element number (Plane stress element, plate element, etc.)
Direction
Assign the projection direction for the line or surface of the defined projection base.
Normal : Projection direction normal to the line or surface of the projection base
Direction Vector : Projection in an arbitrary direction. Enter each of the x, y, z vector components in the projection direction.
Divide
Create additional elements in between the existing nodes and projected nodes along the lines of projection at either equal or unequal spacings.
Equal : Equal spacing
Number of Divisions : Number of equal spacings
Parametric Unequal : Unequal spacings defined in terms of distance ratios.
Ratio : Locations of division along the total projection length expressed in terms of distance ratios.
(ex: 0.4, 0.6, 0.9)
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 Elem.
If line elements exist at the locations to which nodes are project-copied or moved, divide the line elements at the corresponding nodes. Click to control the tolerance for the intersecting condition of a node and a line element.
