Autodesk.Revit.DB.CurveLoopIterator

The Autodesk.Revit.DB.CurveLoopIterator class is part of the Revit API and is used to iterate through CurveLoop objects, each of which represents a closed loop of curves within a face of a solid element.

Properties

The CurveLoopIterator class has the following properties:

• Current - Gets the current CurveLoop object in the iteration.
• IsDone - Indicates whether the iteration has reached the end of the CurveLoop objects.

Methods

The CurveLoopIterator class has the following methods:

• MoveNext() - Moves the iterator to the next CurveLoop object in the iteration.

Example Usage

// Get the solid element
Solid solid = element.get_Geometry(new Options()) as Solid;

// Get the faces of the solid
foreach (Face face in solid.Faces)
{
   // Get the loop of curves for each face
   CurveLoop loop = face.GetEdgesAsCurveLoops()[0];

   // Create an iterator for the loop
   CurveLoopIterator iterator = new CurveLoopIterator(loop);

   // Iterate through the curves in the loop
   while (!iterator.IsDone)
   {
      Curve curve = iterator.Current;

      // Do something with the curve...
      
      iterator.MoveNext();
   }
}

Conclusion

The Autodesk.Revit.DB.CurveLoopIterator class provides a convenient way to iterate through the curves of a CurveLoop object within a face of a Revit solid element. Its properties and methods allow for efficient and effective traversal of these curve loops, which is often necessary when working with complex Revit models.
