Add Arrowheads to Curves
Demonstrates how to decorate curves in a Rhino model with arrowheads.
partial class Examples
{
public static Rhino.Commands.Result ObjectDecoration(Rhino.RhinoDoc doc)
{
// Define a line
var line = new Rhino.Geometry.Line(new Rhino.Geometry.Point3d(0, 0, 0), new Rhino.Geometry.Point3d(10, 0, 0));
// Make a copy of Rhino's default object attributes
var attribs = doc.CreateDefaultAttributes();
// Modify the object decoration style
attribs.ObjectDecoration = Rhino.DocObjects.ObjectDecoration.BothArrowhead;
// Create a new curve object with our attributes
doc.Objects.AddLine(line, attribs);
doc.Views.Redraw();
return Rhino.Commands.Result.Success;
}
