How to Create a model Line with C#

ahmadkhalaf7892 — Tue, 08 Nov 2022 07:33:16 GMT

Hi Guys, I am a total beginner in C# and Revit API my first task is to draw a model Line in Revit with an elevation for example
Start point XYZ(0,0,0) End Point XYZ(0,0,10);
Any Idea how I can achieve it?
Thanks

Hi @ahmadkhalaf7892 ,

Please try using this below code

XYZ startPt = new XYZ(0, 0, 0); XYZ endPt = new XYZ(0, 0, 10); Curve curve = Line.CreateBound(startPt,endPt); Plane plane = Plane.CreateByNormalAndOrigin(new XYZ(0,1,0), new XYZ(0, 0, 0)); SketchPlane sketchPlane = SketchPlane.Create(doc,plane); doc.Create.NewModelCurve(curve, sketchPlane);

Hi Kumar it didn't work, maybe I did something wrong in my script ? Do you know what's the problem?
THanks

Hi @ahmadkhalaf7892 ,

If you are adding/modifying/deleting an element in the Revit project via Revit API, then, your code should be inside the transaction.

Transaction transaction1 = new Transaction(doc); transaction1.Start("Create Model Line"); XYZ startPt = new XYZ(0, 0, 0); XYZ endPt = new XYZ(0, 0, 10); Curve curve = Line.CreateBound(startPt, endPt); Plane plane = Plane.CreateByNormalAndOrigin(new XYZ(0,1,0),new XYZ(0, 0, 0)); SketchPlane sketchPlane = SketchPlane.Create(doc, plane); doc.Create.NewModelCurve(curve, sketchPlane); transaction1.Commit();

Forgive me for asking but I am a total beginner I started two days ago and only want a line to be drawn inside Revit, I am not aiming to edit an element for now.
Can you please show me a capture or anything that shows where the code should be .
