Add Cylinder

Demonstrates how to construct a cylinder using a center-point, height and axis.

partial class Examples
  public static Rhino.Commands.Result AddCylinder(Rhino.RhinoDoc doc)
    Rhino.Geometry.Point3d center_point = new Rhino.Geometry.Point3d(0, 0, 0);
    Rhino.Geometry.Point3d height_point = new Rhino.Geometry.Point3d(0, 0, 10);
    Rhino.Geometry.Vector3d zaxis = height_point - center_point;
    Rhino.Geometry.Plane plane = new Rhino.Geometry.Plane(center_point, zaxis);
    const double radius = 5;
    Rhino.Geometry.Circle circle = new Rhino.Geometry.Circle(plane, radius);
    Rhino.Geometry.Cylinder cylinder = new Rhino.Geometry.Cylinder(circle, zaxis.Length);
    Rhino.Geometry.Brep brep = cylinder.ToBrep(true, true);
    if (brep != null)
    return Rhino.Commands.Result.Success;
