3D curve rebar

[Anonymous]

It seems the methods provided by the Revit API can only create rebar in a plane. Is there a way to create rebar along a space (3D) curve?

Thanks

Pleas always search the available resources before asking a question here.

In this case, please search the Revit SDK samples for `RebarShape`.

One of the samples provides is MultiplanarRebar. 

This sample is to demo multiplanar rebar creation in API. A user scenario of multiplanar rebar is corbel reinforcement. This sample reinforces sloped corbels.

Cheers,

Hi Jeremy, thank you very much for your reply. What I want is a method to create a rebar with an arbitrary 3D shape, which is sometimes required in the longitudinal reinforcement of double-curved bridge. I created a HermiteSpline from a series of XYZ points and use the curve as the center line of rebar.  The MultiplanarRebar may not be the solution. However, I found the free form rebar may be able to do that. I will try that.

Thanks

Maybe this free form rebar distribution is exactly what you are after:

Hi Jeremy, I can get what I want using the free form rebar. Thank you for your help.

Congratulations!

Thank you for your appreciation.

Please share a snippet or two of sample code to show others how you ended up solving this.

Thank you!

Cheers,

Jeremy

The code is really simple, as follows:

List<XYZ> pts = …  // define my XYZ points

Curve curve3D = HermiteSpline.Create(pts, false);

CurveLoop curveLoop = new CurveLoop();

curveLoop.Append(curve3D);

List<CurveLoop> curveLoops = new List<CurveLoop>();

curveLoops.Add(curveLoop);

Rebar rebar = Rebar.CreateFreeForm(document, barType, host, curveLoops, out error);

This method is simple, and no constrain can be applied. But it seems good enough for my current task.

Thanks,

Hello, how did you develop the plug-in for the free form reinforcement shown in the video?
