Summary
Returns arc and track objects whose Width property complies with the Query.
Syntax
W : 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(W) : Number– to specify a width in mil.AsMM(– to specify a width in mm.W) : Number
Example Usage
W = 20
Returns all arc and track objects that have a Width property which is 20 current measurement units.
W >= 0.381
Returns all arc and track objects that have a Width property which is greater than or equal to 0.381 current measurement units.
AsMils(W) Between 10 And 30
Returns all arc and track objects that have a Width property which is greater than or equal to 10mil and less than or equal to 30mil.
AsMM(W) < 0.635
Returns all arc and track objects that have a Width property which is less than 0.635mm.
Tips
- The Width property is only defined for arc and track objects.
- This function is an alias for the Width function.
