Summary
Returns all angular dimension, baseline dimension, linear diameter dimension, linear dimension, and radial diameter dimension objects whose Arrow Length property complies with the Query.
Syntax
DimensionArrowLength : 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(DimensionArrowLength) : Number– to specify a length in mil.AsMM(DimensionArrowLength) : Number– to specify a length in mm.
Example Usage
DimensionArrowLength = 100
Returns all angular dimension, baseline dimension, linear diameter dimension, linear dimension, and radial diameter dimension objects that have an Arrow Length property which is 100 current measurement units.
DimensionArrowLength >= 2.286
Returns all angular dimension, baseline dimension, linear diameter dimension, linear dimension, and radial diameter dimension objects that have an Arrow Length property which is greater than, or equal to, 2.286 current measurement units.
AsMils(DimensionArrowLength) Between 80 And 120
Returns all angular dimension, baseline dimension, linear diameter dimension, linear dimension, and radial diameter dimension objects that have an Arrow Length property which is greater than, or equal to, 80mil and less than, or equal to, 120mil.
AsMM(DimensionArrowLength) < 2.794
Returns all angular dimension, baseline dimension, linear diameter dimension, linear dimension, and radial diameter dimension objects that have an Arrow Length property which is less than 2.794mm.
Tips
- The Arrow Length property is only defined for angular dimension, baseline dimension, linear diameter dimension, linear dimension, and radial diameter dimension objects.
- The child objects of angular dimension, baseline dimension, linear diameter dimension, linear dimension, and radial diameter dimension objects returned by the Query, are not returned.
