Nexus message

This documentation page references Altium NEXUS/NEXUS Client (part of the deployed NEXUS solution), which has been discontinued. All your PCB design, data management and collaboration needs can now be delivered by Altium Designer and a connected Altium 365 Workspace. Check out the FAQs page for more information.

Parent page: PCB Query Functions - Fields

Summary

Returns all polygon pour objects whose Arc Approximation property complies with the Query.

Syntax

PolygonArcApproximation : 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(PolygonArcApproximation) : Number – to specify an approximation in mil.
  • AsMM(PolygonArcApproximation) : Number – to specify an approximation in mm.

Example Usage

PolygonArcApproximation = 0.0127
Returns all polygon pour objects that have an Arc Approximation property which is 0.0127 current measurement units.

PolygonArcApproximation >= 1.27
Returns all polygon pour objects that have an Arc Approximation property which is greater than, or equal to, 1.27 current measurement units.

AsMils(PolygonArcApproximation) Between 0.01 And 0.02
Returns all polygon pour objects that have an Arc Approximation property which is greater than, or equal to, 0.01mil and less than, or equal to, 0.02mil.

AsMM(PolygonArcApproximation) < 0.0127
Returns all polygon pour objects that have an Arc Approximation property which is less than 0.0127mm.

Tips

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