Summary

Returns all polygon pour objects whose Island Area Threshold property complies with the Query.

Syntax

PolygonIslandAreaThreshold : 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(PolygonIslandAreaThreshold) : Number – to specify a threshold in mil.
  • AsMM(PolygonIslandAreaThreshold) : Number – to specify a threshold in mm.

Example Usage

PolygonIslandAreaThreshold = 2
Returns all polygon pour objects that have an Island Area Threshold property which is 2 sqaure (current) measurement units.

PolygonIslandAreaThreshold >= 2
Returns all polygon pour objects that have an Island Area Threshold property which is greater than, or equal to, 2 sqaure (current) measurement units.

AsMils(PolygonIslandAreaThreshold) Between 3000 And 4000
Returns all polygon pour objects that have an Island Area Threshold property which is greater than, or equal to, 3000 square mils and less than, or equal to, 4000 square mils.

AsMM(PolygonIslandAreaThreshold) < 1.016
Returns all polygon pour objects that have an Island Area Threshold property which is less than 1.016 square mm.

Tips

  1. The Island Area Threshold property is only defined for polygon pour objects.
  2. The child objects of polygon pour objects returned by the Query, are not returned.
