Dynamo represents all Geometry in meters, while Revit uses feet.All Geometry coming out of Dynamo Nodes are NOT Revit GeometryObject’s, so they need to be converted when used with the Revit API.For example, a CurveLoop comprising the four edges of a rectangle in the order, with three of the lines oriented in the counter-clockwise direction of the rectangle and the fourth oriented in the clockwise direction, is discontinuous.Īlso see Sort and Orient Curves to Form a Contiguous Loop Geometry Objects Conversion These definitions take the order of the curves and the curves’ directions into account. the end of each curve coincides with the start of the next one (if there is a next curve).It may be either closed (where the start and end points coincide) or open.Ī CurveLoop is said to be “continuous” if either:.The curves must typically be continuous.Or can be extracted from an element using GetBoundarySegments(): Required for Filled Regions and Area Loads for example.ĬurveLoops can be created from line start and end points: Use the correct function depending on the element type:Ī class that represents a chain of curves.
