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.
