Spool Reference Dimensions

If the user has set up reference dimensions in the DESIGN database, they can display them in Isodraft. To define a reference dimension, the user must specify:

• A reference datum (see Setting up a Reference Datum).

• A point on a Pipe which the user wants to dimension (see Setting up a Reference Dimension).

The dimensions will be drawn from the reference datum to the point on the Pipe.

Note: Reference dimensions do not affect normal dimensioning. Also, they can be switched on and off independently of other types of dimensions. Refer to REFDIMENSIONS command.
