Revit 2018二次开发 创建草图平面SketchPlane

Revit 2018二次开发 创建草图平面SketchPlane，分为两步

Plane plane = Plane.CreateByNormalAndOrigin(XYZ.BasisZ, XYZ.Zero);
SketchPlane modelSketch = SketchPlane.Create(RevitDoc, plane);

先做Plane，后做SketchPlane

        {
            UIDocument uiDoc = commandData.Application.ActiveUIDocument;
            Document RevitDoc = commandData.Application.ActiveUIDocument.Document;
            

            using (Transaction transaction = new Transaction(RevitDoc))
            {
                transaction.Start("Create Model Line");
                Line geoLine = Line.CreateBound(XYZ.BasisY * 10, XYZ.BasisX * 10);
                Plane plane = Plane.CreateByNormalAndOrigin(XYZ.BasisZ, XYZ.Zero);
                SketchPlane modelSketch = SketchPlane.Create(RevitDoc, plane);
                ModelCurve modelLine = RevitDoc.Create.NewModelCurve(geoLine, modelSketch);
                transaction.Commit();
            }







            return Result.Succeeded;

        }
