Properties for "Rhino.Geometry.Unroll.AddFollowingGeometry" output curves

[Crash]

Hi everyone

I tested “Rhino.Geometry.Unroll.AddFollowingGeometry” function. Is it possible to set properties for output curves (layers, color etc.). I would like them to have same properties as input curves.

I have not seen this option but maybe there is another way.

I’m using Rhino 5.

Hi Crash

Not sure if this is available in V5 as well, but in V6 the unroller has the method

Maybe this will get you on track:

Hi @richard_schaffranek, It doesn’t take much effort to sort the output following curves if needed: private void RunScript(Brep brep, List<Curve> curves, Curve extra, ref object A) { var unroller = new Unroller(brep); unroller.AbsoluteTolerance = RhinoDocument.ModelAbsoluteTolerance; unroller.AddFollowingGeometry(curves); unroller.AddFollowingGeometry(extra); Curve[] unrolled_curves; Point3d[] unrolled_points; TextDot[] unrolled_dots; var breps = unroller.P…

Request: Could we get more options to attach metadata to the unroll class?

Hi @PaulPoinet, Just curious, are you familiar with Unroller.FollowingGeometryIndex? Here is an example: https://github.com/mcneel/rhino-developer-samples/blob/6/rhinopython/SampleUnroller.py – Dale

Does that help?

Hi Willem

Thanks for quick reply.
It looks good.

But only for Rhino 6 .: (

I tried to change output curves after creation but number of created items sometimes differs from input numbers. It will be hard without “FollowingGeometryIndex”.

So I need to know how many output curves are created for each input curve.
can I get this information from “Unroller”?
