Composing Sheet Models with References

Creation of hard-copy prints of your designs, in the form of drawings, requires initial setting up of Sheet models. A Sheet model typically consists of a collection of design model references that are scaled and positioned as necessary to create a drawing, usually inside a drawing border, which can be printed.

In the Sheet model, you then add dimensions and other notes as required. You can use the reference tools to manipulate the references as needed to create the drawing. Typically, this may include folding, copying, scaling, clipping, rotating, masking, and/or mirroring the references. When working with 3D references, you can use true hidden line representation to display the reference correctly for the drawing.

Sheet models can be thought of as virtual sheets of paper, which are printed to produce hard-copy documents. Design geometry that appears in a Sheet model is attached as references, either from models in the same DGN file, or from models in other DGN files, or a combination of both.
