Create Vertices

) to create vertices when the geometry and mesh are empty or when the geometry is empty and the mesh includes an node. Convert existing mesh vertices into vertex elements or create new vertex elements. The new vertices can be created in empty space or be created to overlap existing mesh.

•

For an imported mesh, right-click in the window to open up The Graphics Context Menu and select (

). In 3D, do this from the menu.

•

For a 3D mesh, it is available from the menu (

) on the ribbon. For a 2D mesh, click the (

) directly.

Enter the properties for the node using the following sections:

From the list, select (the default) to specify positions by clicking on mesh vertices in the Graphics window. Alternatively, choose to specify the positions of the vertices.

Click the button to toggle between turning ON and OFF the mesh vertex selection. This enables selection by clicking in the Graphics window. When the button is toggled ON, the will automatically be turned ON to facilitate the selection of vertices. It is possible enter the exact , , and (3D only) coordinates manually in the table, but the vertex specification is better suited for this purpose. Selected vertices are highlighted in the Graphics. Click a second time on the same vertex to remove it from the selection.

	It is only possible to select mesh vertices on boundaries in 3D which are visible in the Graphics window. Use Click and Hide and the clipping tools to get access to interior boundaries. Rotate the mesh to make the opposite side come into view.

Valid inputs for the , , and (3D only) fields are either arrays of the same length or scalars. If both arrays (of size bigger than one) and scalars are given, the scalars are interpreted as an array of constant value. Use the button (

) if desired to create an array of coordinate values.

Use the field to specify a maximum distance within which the specified point will snap to the closest mesh point. A vertex element will be created at the snapped point. If there are no such mesh points within the tolerance, both a mesh point and a vertex element will be created at the specified coordinates. The value in the field is relative to the size of the mesh including the added vertices. It is relative to the diameter of the bounding box and should therefore be given as a value between 0 and 1. The specified points are not allowed to be within the relative snapping tolerance of each other.
