Summary
Returns polygon pour objects.
Syntax
IsPoly : Boolean
Example Usage
IsPoly
IsPoly = True
Returns all polygon pour objects.
Not IsPoly
IsPoly = False
Returns all objects except polygon pour objects.
Tips
- This function is an alias for the IsPolygon function.
- When defining an Electrical Clearance rule for polygon pours, you must use the InPolygon (or InPoly) attribute check, rather than the IsPolygon (or IsPoly) object type check. This is because the clearance rules operate on the primitives (regions, tracks and arcs) that make up, or are in the polygon pour, rather than the polygon pour as a whole object. A valid clearance rule for polygon pours would be between InPolygon objects and All other objects.
