Returns pad objects whose Pad Corner Radius (%) (Bottom Layer) property complies with the Query.


Pad_CornerRadius_BottomLayer = CornerRadius_String
Pad_CornerRadius_BottomLayer <> CornerRadius_String

CornerRadius_String specifies the corner radius, expressed as a percentage.

Example Usage

Pad_CornerRadius_BottomLayer = '50%'
Returns all pad objects whose Pad Corner Radius (%) (Bottom Layer) property equals 50%.

Pad_CornerRadius_BottomLayer <> '30%'
Returns all objects except for pad objects whose Pad Corner Radius (%) (Bottom Layer) property equals 30%.


  1. The single quote characters (') at the start and end of CornerRadius_String are mandatory.
  2. For simple pads (with Stack Mode set to Simple) the Pad Corner Radius (%) (Bottom Layer) property will be the same as the Pad Corner Radius (%) (All Layers) property, since the specified Corner Radius is used for all signal layers.
  3. The Pad Corner Radius (%) (Bottom Layer) property is only defined for pad objects.
