Dimension PropertyManager
Allows you to dimension a drawing with smart
or DimXpert
dimensioning.
Dimension Assist Tools
Smart dimensioning 
. Lets you create dimensions with the Smart Dimension
tool.
DimXpert 
.
Lets you apply dimensions to fully define manufacturing features (patterns,
slots, pockets, fillets, etc.) and locating dimensions.
Pattern Scheme
Applies the selected dimensioning scheme to patterns.
Polar dimensioning 
. Creates a scheme consisting of a callout and sometimes an
angular locating dimension. The dimensions created are diametric, radii,
and angular.
Linear dimensioning 
. Creates linear dimensions for a pattern.
Instance counts for polar and linear dimensions
are supported for patterns created in the SolidWorks software only.
Dimensioning Scheme
Applies the selected dimensioning scheme, Baseline
or Chain 
, to manufacturing features and locating dimensions.
Datum
By Vertex/hole center.
Measures the manufacturing features and the locating dimensions from the
entity you select in the graphics area. The vertex can be a true vertex
or the centerpoint of a circle.
By Selection.
Measures the manufacturing features and the locating dimensions from the
X and Y
edges you select by creating a virtual sharp. You can drag the origin
to rotate it, or set a Rotation
angle. If the X and Y edges intersect, you must use the By
Vertex option.
Layer 
In drawings with named layers,
select a layer.
