Rebar Location Controlling

arshad.k — Tue, 25 Jan 2022 07:20:52 GMT

Hello Everyone!

I try to create rebar using API, I choose CreateFromRebarShape Method for Creation. And I successfully created the rebar

but one thing, rebar which I have created is always placing outside of the host and I can't able to control the location of

rebar and its layout. Can anybody help in solving this.

I have attached my code and error image below.

#region Create Reabar in Shape Method using (Transaction createRebar = new Transaction(revitDoc, "Create Rebar")) { createRebar.Start(); //Pick Host Element Reference hostElementReference = revitUi.Selection.PickObject(ObjectType.Element); Element hostElement = revitDoc.GetElement(hostElementReference); //Select Planar Face to Place Rebar Reference selectedRefer = revitUi.Selection.PickObject(ObjectType.Face); PlanarFace plane=revitDoc.GetElement(selectedRefer).GetGeometryObjectFromReference(selectedRefer) as PlanarFace; //Get Rebar Shape RebarShape rebarShape = new FilteredElementCollector(revitDoc).OfClass(typeof(RebarShape)).Where(x => x.Name.Equals("M_08")).FirstOrDefault() as RebarShape; //Get Rebar Type RebarBarType rebarType = new FilteredElementCollector(revitDoc).OfClass(typeof(RebarBarType)).OfCategory(BuiltInCategory.OST_Rebar).Where(x => x.Name.Equals("10M")).FirstOrDefault() as RebarBarType; //Create Rebar Rebar bar = Rebar.CreateFromRebarShape(revitDoc, rebarShape, rebarType, hostElement, plane.Origin, plane.XVector, plane.YVector); //Create Layout RebarShapeDrivenAccessor rebarShapeDrivenAccessor = bar.GetShapeDrivenAccessor(); rebarShapeDrivenAccessor.SetLayoutAsFixedNumber(10, UnitUtils.ConvertToInternalUnits(1800, DisplayUnitType.DUT_MILLIMETERS), true, true, true); createRebar.Commit(); } #endregion

I seem to remember this being discussed here in the past couple of months... I think you can find the answer by searching for "rebar cover". Good luck!

Hi @arshad.k ,

I tested the sample code you attached.

I'm not getting any such errors.

I used this sample code
Rebar bar = Rebar.CreateFromRebarShape(doc, rebarShape, rebarType, hostElement, planeF.Origin, new XYZ(1,0,0), new XYZ(0,1,0));

Which Revit version are you using?

Could you please send us a small non-confidential reproducible sample code(I think we already have the sample code) and a simple non-confidential Revit model(rvt file) to recreate the issue?

Also, send us the detailed step-by-step instructions for reproducing the issue(i.e)which plane to choose

Please refer to the thread on constraining stirrups to the cover of the host element for a complete answer:
