Summary
Returns leader dimension objects whose Dot Size property complies with the Query.
Syntax
LeaderDimensionDotSize : Number
Number will follow the measurement units currently employed for the document – either Imperial (mil; 1mil = 0.001inch) or Metric (mm; 1mm = 0.001meter).
A specific option for the measurement unit can be specified – overriding the default units specified at the document level – through use of an additional measurement unit-based keyword:
AsMils(LeaderDimensionDotSize) : Number– to specify a size in mil.AsMM(LeaderDimensionDotSize) : Number– to specify a size in mm.
Example Usage
LeaderDimensionDotSize = 40
Returns all leader dimension objects that have a Dot Size property which is 40 current measurement units.
LeaderDimensionDotSize >= 1.143
Returns all leader dimension objects that have a Dot Size property which is greater than or equal to 1.143 current measurement units.
AsMils(LeaderDimensionDotSize) Between 30 And 50
Returns all leader dimension objects that have a Dot Size property which is greater than or equal to 30mil and less than or equal to 50mil.
AsMM(LeaderDimensionDotSize) < 0.889
Returns all leader dimension objects that have a Dot Size property which is less than 0.889mm.
Tips
- The Dot Size property is only defined for leader dimension objects.
- The child objects of leader dimension objects returned by the Query are not returned.
