Chains a group of dimensions into the appropriate margins based on the position at which the software places the dimensioning points.
In the following example, the amount of space between the dimension lines of the first and third dimensions in the chain allows the software to embed the measurements.
Very little space exists between the second set of dimension lines. Therefore, the software rotates the measurement vertically and places it above the chain.
Likewise, the fourth set of dimension lines has a small amount of space. In this case, the measurement is rotated; however, there is enough space for the software to embed the measurement.

keepTopOrBottomDup
Allows you to place a label on either the topmost or bottommost object in a group of objects aligned at identical X positions along a vertical axis. If the value for keepTopOrBottomDup is 0, then only the topmost point of an aligned set of points is considered for dimensioning. If the value is set to -1, then only the bottommost point of an aligned set of points is considered for dimensioning.
keepLeftOrRightDup
Allows you to place a label on either the leftmost or rightmost object in a group of objects aligned at identical Y positions along a horizontal axis. If the value for keepLeftOrRightDup is set to 0, then only the leftmost point in a horizontally aligned set of points is considered in dimensioning. If the value is set to -1, then only the rightmost point in a horizontally aligned set of points is considered for dimensioning.
orientation
Allows you to specify the positional orientation of the label with respect to the labeled object.
maxDimOffset
Determines the maximum linear paper space distance between consecutive witness lines in a linear distance dimension group.
maxWitnessLength
Controls the length of witness lines so that you can determine how far across the drawing the line is drawn. Points that fall outside the maximum witness length are eliminated from consideration.
overall
Places an additional dimension over each dimension chain cluster identified by the rule.
trimWitness
Determines whether or not a dimension witness line extends into the drawing view to the dimensioned object or stops at the drawing view. If the trimWitness value is selected, then the software trims the dimension witness lines. If the value is cleared, then the dimension witness lines continue into the drawing view to the dimensioned objects.
