源代码

//Getting Access to Revit

revitUi = revitUiApp.ActiveUIDocument;
revitDoc = revitUi.Document;

#region Create Model Lines in Picked Reference
using (Transaction CreateModelLines = new Transaction(revitDoc, "Create Model Lines"))
{
CreateModelLines.Start();
//Pick Plane
Reference faceRefer = revitUi.Selection.PickObject(ObjectType.Face);
//Create Sketch Plane
SketchPlane skp = SketchPlane.Create(revitDoc, faceRefer);
revitDoc.ActiveView.SketchPlane = skp;
revitDoc.ActiveView.ShowActiveWorkPlane();
//Pick Edge to Create Model line
Reference edgeRefer = revitUi.Selection.PickObject(ObjectType.Edge);
Edge edge = revitDoc.GetElement(edgeRefer).GetGeometryObjectFromReference(edgeRefer) as Edge;
Curve Curve = edge.AsCurve();
revitDoc.Create.NewModelCurve(Curve, skp);

CreateModelLines.Commit();
}
