Summary

Returns via objects whose X Size (Mid Layer 29) property complies with the Query.

Syntax

ViaSize_MidLayer29 : 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_MidLayer29) : Number – to specify a size in mil.
AsMM(ViaSize_MidLayer29) : Number – to specify a size in mm.

Example Usage

ViaSize_MidLayer29 = 100
Returns all via objects whose X Size (Mid Layer 29) property is equal to 100 current measurement units.

ViaSize_MidLayer29 >= 4.064
Returns all via objects whose X Size (Mid Layer 29) property is greater than, or equal to, 4.064 current measurement units.

AsMils(ViaSize_MidLayer29) > 80
Returns all via objects whose X Size (Mid Layer 29) property is greater than 80mil.

AsMM(ViaSize_MidLayer29) Between 1.524 And 3.81
Returns all via objects whose X Size (Mid Layer 29) property is greater than or equal to 1.524mm and less than or equal to 3.81mm.

ViaSize_MidLayer29 <> 50
Returns all via objects whose X Size (Mid Layer 29) property is not equal to 50 current measurement units.

Tips

For simple vias (with Stack Mode set to Simple) the X Size (Mid Layer 29) property will be the same as the X Size (All Layers) property, since the specified size is used for all signal layers.
While the PCB List panel displays the X Size (All Layers) property, the PCB Inspector panel displays this property by another name - Via Diameter.
For Top-Middle-Bottom vias (with Stack Mode set to Top-Middle-Bottom) the X Size (Mid Layer 29) property will be the same as the X Size (Mid Layer 1) property, since the size specified for Signal Layer 1 is applied to all internal ('middle') signal layers.
The X Size (Mid Layer 29) property is only defined for pad and via objects.
