pytha.analyze_polyline

Analyzes the edges of a part and returns them as one or more polyline chains.

This is the inverse operation to create_polyline: the connected edges of the given part are grouped into chains and returned as point sequences. Each chain is reported as either "open" or "closed".

Note: If the part may contain arcs and you want them reconstructed as arc segments, use analyze_polyline_ex instead.

pytha.analyze_polyline(element)

Parameter	Type	Description

points	{{x,y,z}, ...}	Coordinates of the chain points. For a closed chain the initial point is not repeated at the end.

Notes:

• The chains are returned in the order found by the internal edge-ordering routine.
• For a closed chain, the first point is not duplicated as the last point.
