How to create a reference line in revit API

Anonymous — Thu, 17 Dec 2020 10:21:22 GMT

I'm trying to create a reference line (not a reference plane) between two points on a plane. I couldn't find any method except for one method that changes the type of a model curve to a reference line. How can I do that through API?

for instance, please assume these two points:

XYZ point1 = new XYZ(30, 12, 0);

XYZ point2 = new XYZ(10, 30, 0);

Thanks a lot in advance!

Hi @Anonymous ,

Try using the below code

Plane P = Plane.CreateByNormalAndOrigin(XYZ.BasisZ, new XYZ(0, 0, 0)); SketchPlane sp = SketchPlane.Create(doc, P); XYZ startPoint; XYZ endPoint; Line l1 = Line.CreateBound(startPoint,endPoint); ModelLine mLine = doc.FamilyCreate.NewModelCurve(l1,sp) as ModelLine; if (mLine!=null) { mLine.ChangeToReferenceLine(); }
