## 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.
