Drawing Scale
DelDOT CADD Standards Manual
The Drawing Scale dialog box allows the scale of a drawing to be changed at any time by
selecting the appropriate scale factor from the Drawing Scale dialog box. When selected,
the scale factor is stored within the design file and affects the scale dependent items such
as text, cells and line styles.
Figure 2 : Drawing Scale Settings
All of the scale dependant drawing elements such as text, cells and line styles have been
redefined in the new CADD Standards at a unit scale of 1:1. These elements are then
automatically scaled up or down by the drawing scale factor as they are selected from the
DelDOT Menu Bar. This helps maintain consistency of scale‐dependant drawing features,
regardless of the scale being used.
Note: The Drawing Scale dialog box can be activated by entering dialog drawingscale
open in the MicroStation Key‐In command line. The Drawing Scale dialog box can also be
activated by choosing DelDOT Common > Set Model Scale/Working Units from the
DelDOT Menu Bar.
The standard DelDOT drawing / annotation scales used in the preparation of DelDOT plan
sets are defined in the deldot_scales.def file, and can be obtained from the DelDOT DRC
website.
Note: The MicroStation configuration variable MS_CUSTOMSCALEDEF is used to assign the
scale definition file.
Engineering scales shall be used for all roadway sheets and for bridge plan view sheets.
Architectural scales are used for annotating bridge details and occasionally roadway
details.
