Summary
Returns all pad objects whose Hole Length property complies with the Query.
Syntax
SlotHoleLength : 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(SlotHoleLength) : Number– to specify a length in mil.AsMM(SlotHoleLength) : Number– to specify a length in mm.
Example Usage
SlotHoleLength = 50
Returns all pad objects that have an Hole Length property which is 50 current measurement units.
SlotHoleLength >= 50
Returns all pad objects that have an Hole Length property which is greater than, or equal to, 50 current measurement units.
AsMils(SlotHoleLength) Between 20 And 50
Returns all pad objects that have an Hole Length property which is greater than, or equal to, 0.5mil and less than, or equal to, 0.6mil.
AsMM(SlotHoleLength) < 1.5
Returns all pad objects that have an Hole Length property which is less than 1.5mm.
Tips
- The Hole Length property is only defined for pad objects.
