■ Dimension in model space for plotting in paper space. This was the

preferred method for complex, multiple-view drawings prior to AutoCAD

2002. Use this method when the dimensions in a drawing need to be

referenced by other drawings (xrefs) or when creating isometric dimensions

in 3D isometric views. To prevent the dimensions in one layout viewport

from being displayed in other layout viewports, create a dimensioning

layer for each layout viewport that is frozen in all other layout viewports.

To create dimensions that are scaled automatically for display in a paper

space layout, set the DIMSCALE system variable to 0.

■ Dimension in layouts. This is the simplest dimensioning method.

Dimensions are created in paper space by selecting model space objects or

by specifying object snap locations on model space objects. By default,

associativity between paper space dimensions and model space objects is

maintained. No additional scaling is required for dimensions created in a

paper space layout: DIMLFAC and DIMSCALE do not need to be changed

from their default value of 1.0000.

NOTE When you dimension model space objects in paper space using associative

dimensions, dimension values for the display scale of each viewport are

automatically adjusted. This adjustment is combined with the current setting for

DIMLFAC and is reported by the LIST command as a dimension style override. For

nonassociative dimensions, you must set DIMLFAC manually.
