Summary
Returns all polygon pour objects whose Grid Size property complies with the Query.
Syntax
PolygonGridSize : 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(PolygonGridSize) : Number– to specify an size in mil.AsMM(PolygonGridSize) : Number– to specify an size in mm.
Example Usage
PolygonGridSize = 20
Returns all polygon pour objects that have an Grid Size property which is 20 current measurement units.
PolygonGridSize >= 1.27
Returns all polygon pour objects that have an Grid Size property which is greater than, or equal to, 1.27 current measurement units.
AsMils(PolygonGridSize) Between 10 And 30
Returns all polygon pour objects that have an Grid Size property which is greater than, or equal to, 10mil and less than, or equal to, 30mil.
AsMM(PolygonGridSize) < 1.016
Returns all polygon pour objects that have an Grid Size property which is less than 1.016mm.
Tips
- The Grid Size property is only defined for polygon pour objects.
- The child objects of polygon pour objects returned by the Query, are not returned.
