Summary
Returns all leader dimension objects whose Arrow Gap property complies with the Query.
Syntax
DimensionArrowGap : 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(DimensionArrowGap) : Number– to specify a gap in mil.AsMM(DimensionArrowGap) : Number– to specify a gap in mm.
Example Usage
DimensionArrowGap = 10
Returns all leader dimension objects that have an Arrow Gap property which is 10 current measurement units.
DimensionArrowGap >= 0.2286
Returns all leader dimension objects that have an Arrow Gap property which is greater than, or equal to, 0.2286 current measurement units.
AsMils(DimensionArrowGap) Between 8 And 12
Returns all leader dimension objects that have an Arrow Gap property which is greater than, or equal to, 8mil and less than, or equal to, 12mil.
AsMM(DimensionArrowGap) < 0.2794
Returns all leader dimension objects that have an Arrow Gap property which is less than 0.2794mm.
Tips
- The Arrow Gap property is only defined for leader dimension objects.
- The child objects of leader dimension objects returned by the Query are not returned.
