Returns all design rule objects having a Rule Type property that complies with the Query.


RuleType = RuleType_String
RuleType <> RuleType_String

RuleType_String must be one of the following strings:

  • Electrical Rules'Clearance', 'Short-Circuit', 'Un-Routed Net', 'Un-Connected Pin', 'Modified Polygon'
  • Routing Rules'Width''Routing Topology''Routing Priority''Routing Layers''Routing Corners''Routing Via Style''Fanout Control', 'Differential Pairs Routing'
  • SMT Rules'SMD To Corner''SMD To Plane''SMD Neck-Down', 'SMD Entry'
  • Mask Rules'Solder Mask Expansion''Paste Mask Expansion'
  • Plane Rules'Power Plane Connect Style''Power Plane Clearance''Polygon Connect Style'
  • Testpoint Rules - 'Fabrication Testpoint Style', 'Fabrication Testpoint Usage', 'Assembly Testpoint Style', 'Assembly Testpoint Usage'
  • Manufacturing Rules - 'Minimum Annular Ring', 'Acute Angle', 'Hole Size', 'Layer Pairs', 'Hole To Hole Clearance', 'Minimum Solder Mask Sliver', 'Silk To Solder Mask Clearance', 'Silk To Silk Clearance', 'Board Outline Clearance'
  • High Speed Rules - 'Parallel Segment', 'Length', 'Matched Lengths', 'Daisy Chain Stub Length', 'Vias Under SMD', 'Maximum Via Count', 'Max Via Sub Length (Back Drilling)'
  • Placement Rules'Room Definition', 'Component Clearance', 'Component Orientations', 'Permitted Layers', 'Nets to Ignore', 'Height'
  • Signal Integrity Rules - 'Signal Stimulus', 'Overshoot - Falling Edge', 'Overshoot - Rising Edge', 'Undershoot - Falling Edge', 'Undershoot - Rising Edge', 'Impedance', 'Signal Top Value', 'Signal Base Value', 'Flight Time - Rising Edge', 'Flight Time - Falling Edge', 'Slope - Rising Edge', 'Slope - Falling Edge', 'Supply Nets'

Example Usage

RuleType = 'Clearance'
Returns all design rule objects whose Rule Type property is Clearance.

RuleType <> 'Paste Mask Expansion'
Returns all objects except design rule objects whose Rule Type property is Paste Mask Expansion.

IsRule && RuleType <> 'Height'
Returns all design rule objects whose Rule Type property is not Height.


  1. The Rule Type property is only defined for design rule objects.
  2. The single quote characters (') at the start and end of RuleType_String are mandatory.
