In my C# program, I have 3 points and 1 curve, I want to create a triangle object to sweep.
I’ve searched in rhino library but there is no structure or class describes a polygon (only Rhino.Display.CustomDisplay.AddPolygon(), but it isn’t necessary in my situation).
I need your help!
To get the triangle you can do this:
Dim PtList As New List(Of Geometry.Point3d)
Dim Crv As Geometry.Curve = Geometry.Curve.CreateControlPointCurve(PtList, 1)
Dim CrvGuid as guid = doc.objects.addcurve(crv)
the result is a closed curve.
next is creating a planarSrf with the curve and I think its easiest with RhinoApp.Runscript like:
Dim PlanarSrf as Guid = doc.Objects.MostRecentObject.Id
Sweep2 can possibly also be done with the rhinoscript but then you need to add -_selID and curve.id etc.
Hope I pushed you in the right direction
I see the sweep in RhinoCommon needs curves
Dim g As New Geometry.SweepOneRail
Dim B as brep = g.PerformSweep(Rail, Crv)
So you dont need the planarsrf part
In g. you can set some settings.
I tried your way and it was very good!
Thank you very much!
