Use the Node Edit panel to associate nodes to a point, line, or surface/solid face; move nodes along a surface; place a node at a point on a surface; remap a list of nodes to a line; or project nodes to an imaginary line passing through two nodes.
The Node Edit panel contains separate subpanels for each type of edit procedure. Settings are preserved if you switch panels, but selections of nodes, surfaces, and so on are not. After selections and criteria are specified, edits are executed via a number of command buttons located along the right-hand edge of the panels in some cases, or executed automatically in others.
The Nodes Edit panel contains the following subpanels, focused on a different form of node edit function:
The Associate subpanel creates an association between the selected nodes and a selected piece of geometry. Nodes are projected to the geometry, provided the distance to the selected geometry is within the search tolerance. The tolerance is used to create a search sphere at each of the selected nodes. If the selected geometry is found within that search sphere, the node is projected to the closest point on the geometry. An association is made within the database between the nodes (and corresponding elements) and geometry, so any subsequent selection routines can reference either entity; for example, if creating a boundary condition (such as a force, pressure, or constraint) on the geometry, the boundary condition will be applied to the nodes and or elements upon export. A typical use case would be to apply slight geometry revisions to an existing model.
In the example below, the brown elements extend beyond the boundaries of the red surface. The elements are in a plane, but the surface is curved away from the plane. All of the nodes were selected to associate to the surface. When a small tolerance is specified, only those nodes close enough to the surface are projected and associated to it. In this example, the five highlighted nodes were associated.
with a larger tolerance, all elements around the boundary of the surface are distorted as the nodes are projected out of their original plane and onto the surface.

Use the Move Node subpanel to move nodes in the global coordinate system. Select the nodes to move, define a direction and a step size. Nodes can be moved in the positive or negative direction defined by the movement vector.
Panel Inputs
|
Use the Place Node subpanel to move a single node to a specific location on a destination surface. After selecting the surface, select the node to be placed. Once the node is selected, click the new location for that node on the surface.
Panel Inputs
|
Use the Remap subpanel to remap a series of nodes to a selected line list. In the example below, the selected nodes are mapped to the surface edge.
Panel Inputs
|
Use the Align Node subpanel to snap one or more nodes to an imaginary line connecting two other selected nodes. Any number of nodes may be aligned once a line is defined.
Panel Inputs

The following action buttons appear throughout the subpanels:
