Common Patterns

import Rhino
import scriptcontext as sc
import System.Drawing

doc = sc.doc                                          # Rhino.RhinoDoc
tol = doc.ModelAbsoluteTolerance                      # float
view = doc.Views.ActiveView                           # Rhino.Display.RhinoView
layer_index = doc.Layers.Add("MyLayer", System.Drawing.Color.Red)

# Find a Rhino object from a rhinoscriptsyntax GUID
rhobj = doc.Objects.Find(guid)                        # Rhino.DocObjects.RhinoObject
geom  = rhobj.Geometry                                # Rhino.Geometry.GeometryBase

# Add geometry with attributes
attrs = Rhino.DocObjects.ObjectAttributes()
attrs.LayerIndex = layer_index
attrs.Name = "example"
new_id = doc.Objects.AddCurve(curve, attrs)

Undo

undo_serial = doc.BeginUndoRecord("Batch Op")
try:
    # ... many doc.Objects.* calls ...
    pass
finally:
    doc.EndUndoRecord(undo_serial)
    doc.Views.Redraw()
