1、Revit Family .NET API: Create Frustum of Cone in Family Document Revit .NET has provided the family API for several versions. We did not really address it in the past. In this series of posts, we are going to explore the Revit family .NET API and provide nice sample code and good analysis as usual.L

Here we go.public static ElementId CreateFrustumOfCone(RvtDocument famDoc, XYZ bottomCenter, double bottomRadius, double topRadius, double height) ElementId ret;CurveArray bottomProfile = new CurveArray();Plane plane = new Plane(XYZ.BasisZ,
