Note that this information was pulled directly from SoftPlan's Help system. It is placed here as a convenient reference.

Use the following tables to determine your scale factor when printing drawings with different scales on the same sheet.

Example: If you want to print a detail at ½" = 1'-0" on a sheet that will be printing with ¼" = 1'-0"

½ (0.5) / ¼ (0.25) = 2

If Printing 1/4" = 1'-0" (0.25)
