Creating a Drawing by Scaling the Border to Fit the Design

Create a DGN file and design model, using references as required.
Create a Sheet model (this can be in the same DGN file as your design geometry or in a separate DGN file). Set the Annotation Scale to the main scale that will be used in the drawing.
To the sheet model, reference your border file at the scale required for the drawing.
In the Properties dialog, set Border Attachment to the new attachment.
To the sheet model, reference all views of the design model that are to be at the main scale for the drawing at 1:1 (Full Size). Set nesting to the level necessary to include all required sub references.
For any views that are to be at a different scale from the main scale, reference them at a scale factor of (Main Scale/Required Scale).
If necessary, use the Set Reference Presentation tool, in the References dialog, to change the display format for the references. You can also set the Visible Edges setting in the References dialog list box.
Check that the Annotation Scale lock is enabled.
Place text and dimensions at their required size.
Annotation Scale lock scales the size of the text so that it prints at the required size.
Print the drawing at the scale required.
Note: In the event that you need to change the scale of the drawing, you can quickly change the size of all text, by changing the Annotation Scale setting for the model.
