Summary

Returns all simple via objects whose X Size (All Layers) property complies with the Query.

Syntax

ViaSize : 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(ViaSize) : Number – to specify a via diameter in mil.
  • AsMM(ViaSize) : Number – to specify a via diameter in mm.

Example Usage

ViaSize = 40
Returns all via objects that have a X Size (All Layers) property which is 40 current measurement units.

ViaSize >= 0.508
Returns all via objects that have a X Size (All Layers) property which is greater than or equal to 0.508 current measurement units.

AsMils(ViaSize) Between 30 And 50
Returns all via objects that have a X Size (All Layers) property which is greater than or equal to 30mil and less than or equal to 50mil.

AsMM(ViaSize) < 1.524
Returns all via objects that have a X Size (All Layers) property which is less than 1.524mm.

Tips

  1. The X Size (All Layers) property is only defined for simple via objects - those with their Stack Mode property (as seen from a List panel) set to Simple. When viewing the properties for a via through the Properties panel, this relates to the Simple option being selected, in the Size and Shape section.
  2. When viewing the properties for a selected via in the Properties panel, the X Size (All Layers) property corresponds to the Diameter field, in the Size and Shape section.
  3. This function is an alias for the ViaDiameter function.
