Rhino7SR14 Sweep2Rails methods not working in C# !?

Hello,

I have encountered this problem after upgrading my plugin to SR14.
one command that uses SweepTwoRails() class stopped working

On SR13 the same code worked without problems

I tried workarounds with using Sweep method in brep class but it fails also.
( Brep.CreateFromSweep )

Every time it returns an empty array Rhino.Geometry.Brep[]

Am I missing something here?

here is the piece of code:

                var finalProfile = new SweepTwoRail();
                finalProfile.SweepTolerance = 0.1;
                finalProfile.MaintainHeight = true;

                //var res1 = finalProfile.PerformSweep(path, path2, Profiles);
                //var res1 = finalProfile.PerformSweepRefit(path, path2, Profiles, 0.1);
                var res1 = Brep.CreateFromSweep(path, path2, Profiles, true, 0.1);

                if (res1 == null || res1.Length==0)
                {
                    RhinoApp.WriteLine("Could not create Sweep. Check your profile");
                    doc.Views.EnableRedraw(true, true, true);
                    doc.Objects.AddCurve(Profiles[0]);
                    doc.Objects.AddCurve(Profiles[1]);
                    doc.Objects.AddCurve(path);
                    doc.Objects.AddCurve(path2);

                    return Result.Failure;
                }

( note that I commented out different methods while searching for the solution, the first one was the one I originally used)

I get res1.Length==0 true every time, no matter what I tried

I tried the latest release candidate SR15 and it is not working too…

Thanks in advance

Hi @AleksandarSM,

Can you provide a full working sample that we can run here? Please include the geometry too.

Thanks,

Hi Dale,

I sent you the sample by sendspace. You should also get an email with more info about the issue.

Hi Dale,

The solution you proposed to me works!

here it is:

var finalProfile = new SweepTwoRail();
finalProfile.SweepTolerance = 0.1;
finalProfile.MaintainHeight = true;
finalProfile.ClosedSweep = false; // NEW
Brep[] res1 = finalProfile.PerformSweep(path, path2, Profiles);
