In some cases, one view window may not be sufficient to adequately represent or control a 3D model. For these instances it is possible to create a new model.

To accomplish this, start by dragging and dropping a Coordinate System node form the Node Types dialog into the Graph.

A new coordinate system node "coordinateSystem1" is added to the Graph. The new node's technique should be set to AtModelOrigin. If it is not, use the node drop down menu to select the AtModelOrigin technique. The new coordinate system is not yet complete (incomplete node status indicator)

CoordinateSystem node "coordinateSystem01" with AtModelOrigin technique (highlighted) and incomplete status badge (bottom).

Note: Only one coordinate system named "baseCS" can exist in your DGN. Selecting (Create baseCS) will attempt to create a new coordinate system named "baseCS". If one already exists, the Create baseCS dialog issues a warning.

Create baseCS Sorry, the GC model already contains a node named 'baseCS'. [OK]

The new coordinate system requires a DGN model name as its input (DGNModelName). The coordinate system baseCS is occupying the default Design Model. Continuing with this particular workflow, you now need to create a new DGN model for the new coordinate system. Position the pointer over the input. An input field appears. Click the small arrow to expand the input field. The DGN models existing in the DGN are listed. Select <New...>.

Enter NewModel as the name for the new model in the Create DGN Model dialog.

The new coordinate system is placed at the origin of the new model NewModel, and is displayed in View 3, NewModel. Geometry can now be created in the new coordinate system just as in the baseCS. The properties of geometric elements can be referenced between coordinate systems. For instance, the length of a line in the View window can be referenced or used to define the length of a second line in "View 3, NewModel".
