Summary
Returns all arc objects whose Radius property complies with the Query.
Syntax
ArcRadius : 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(ArcRadius) : Number– to specify a radius in mil.AsMM(ArcRadius) : Number– to specify a radius in mm.
Example Usage
ArcRadius = 300
Returns all arc objects that have a Radius property which is 300 current measurement units.
ArcRadius >= 15.24
Returns all arc objects that have a Radius property which is greater than, or equal to, 15.24 current measurement units.
AsMils(ArcRadius) > 500
Returns all arc objects that have a Radius property which is greater than 500mil.
AsMM(ArcRadius) Between 10.16 And 17.78
Returns all arc objects that have a Radius property which is greater than, or equal to, 10.16mm and less than, or equal to, 17.78mm.
ArcRadius <> 550
Returns all arc objects that have a Radius property which is not equal to 550 current measurement units.
AsMils(ArcRadius) <= 650
Returns all arc objects that have a Radius property which is less than, or equal to, 650mil.
AsMM(ArcRadius) < 11.43
Returns all arc objects that have a Radius property which is less than 11.43mm.
Tips
- The Radius property is only defined for arc objects.
