Custom Object which holdes Grasshopperdefinition....

I am trying to make a Component which holds a grasshopper definition... but i have Problems with Saving it to 3dm . It becomes a Brep again... The guid Attributes does not Help by the way...

   [Guid("688936e4-f804-4c96-91fb-dd6bab3d2f90")]
    public class ExtendBrep : Rhino.DocObjects.Custom.CustomBrepObject
    {

        public ExtendBrep(Rhino.Geometry.Brep brep) : base(brep) { this.Attributes = new ObjectAttributes(); }
        public ExtendBrep() : base() { }

        protected override void OnPicked(Input.Custom.PickContext context, IEnumerable<ObjRef> pickedItems)
        {
            try
            {
                Random random = new Random();
                this.Attributes.ColorSource = ObjectColorSource.ColorFromObject;
                this.Attributes.ObjectColor = System.Drawing.Color.FromArgb(random.Next(0, 255), random.Next(0, 255), random.Next(0, 255));
            }
            catch (Exception e) { System.Windows.Forms.MessageBox.Show("OnPicked: " + e.Message); }
            base.OnPicked(context, pickedItems);
        }

        protected override void OnDuplicate(Rhino.DocObjects.RhinoObject source)
        {
            try
            {
                Random random = new Random();
                this.Attributes.ColorSource = ObjectColorSource.ColorFromObject;
                this.Attributes.ObjectColor = System.Drawing.Color.FromArgb(random.Next(0, 255), random.Next(0, 255), random.Next(0, 255));
            }
            catch (Exception e) { System.Windows.Forms.MessageBox.Show("OnDuplicate: " + e.Message); }
            base.OnDuplicate(source);
        }


    }

Hi Michael,

I don't get it. How does a GH_Document become a Brep?

maybe it is liitle bit offtopic .... i can not register to plugin news group... company settings sorry... so what i want to do is to have custom objects in the document [RhinoDoc] which behave different to a normal Brep or Curve

I use a inheited class from Rhino.DocObjects.Custom.CustomBrepObject but i can not save it to a 3dm file. Maybe where is a special mechanic like attributes existing [Serialize(Guid)]...

With his feature it would be possible to have Custom Objects in the rhinoscreen which a holding an grasshopper xml for example... and could behave totaly different to normal Breps... My problem is not to make such objects but to save whem in a 3dm file...

maybe where is a example existing how to do this, else i have to build a custom format which is not 3dm...

Ah, I didn't even know about the DocObjects.Custom namespace, it has passed me by. I can't answer your question, you may have to contact Steve Baer directly if you're not allowed to ask questions through the regular channels.

if this works you can have family objects like revit with a grasshopper definition.... this would rock. I will write Steve Bear a mail.
