import rhinoscriptsyntax as rs

User Input

Function	Returns
`rs.GetObject(message, filter, preselect, select)`	GUID or `None`
`rs.GetObjects(message, filter)`	list of GUIDs
`rs.GetPoint(message, base_point)`	`Point3d` or `None`
`rs.GetString(message, default, strings)`	str
`rs.GetInteger`, `rs.GetReal`	int / float
`rs.GetBoolean(message, items, defaults)`	list of bools

Common rs.filter.* flags (OR them together):

point=1, point_cloud=2, curve=4, surface=8, polysurface=16,
mesh=32, light=256, annotation=512, instance_reference=4096,
text_dot=8192, grip=16384, detail=32768, hatch=65536,
morph_control=131072, sub_d=262144

Creating Geometry

Function	Notes
`rs.AddPoint(point)`
`rs.AddLine(start, end)`
`rs.AddPolyline(points)`	`points` is a list of 3-tuples
`rs.AddCircle(plane_or_center, radius)`
`rs.AddArc(plane, radius, angle_deg)`	angle in degrees
`rs.AddCurve(points, degree=3)`	NURBS through control points
`rs.AddInterpCurve(points, degree=3)`	NURBS through points
`rs.AddSphere(center, radius)`
`rs.AddBox(corners)`	`corners` = 8 points
`rs.AddPlanarSrf(curves)`	returns list
`rs.AddLoftSrf(curves, ...)`	returns list of GUIDs
`rs.AddExtrusion(profile, path)` / `rs.ExtrudeCurveStraight`

Object Properties

Function	Purpose
`rs.ObjectLayer(id [, layer])`	get/set
`rs.ObjectColor(id [, color])`	RGB tuple
`rs.ObjectName(id [, name])`
`rs.ObjectType(id)`	int matching `rs.filter.*`
`rs.IsCurve / IsSurface / IsBrep / IsMesh / IsPoint(id)`
`rs.DeleteObject(id)` / `rs.DeleteObjects(ids)`
`rs.CopyObject(id, translation)`
`rs.MoveObject(id, translation)`
`rs.RotateObject(id, center, angle, axis=None, copy=False)`	angle in degrees
`rs.ScaleObject(id, origin, scale)`	scale is a 3-tuple

Curves

Function
`rs.CurveLength(id)`
`rs.CurveDomain(id)`	`(t0, t1)`
`rs.EvaluateCurve(id, t)`	`Point3d`
`rs.CurveStartPoint / CurveEndPoint(id)`
`rs.CurveClosestPoint(id, point)`	parameter `t`
`rs.DivideCurve(id, segments, create_points=False, return_points=True)`
`rs.IsCurveClosed / IsCurvePlanar(id)`

Layers

Function
`rs.AddLayer(name, color=None, visible=True, locked=False, parent=None)`
`rs.CurrentLayer([layer])`
`rs.LayerNames()`	list
`rs.LayerVisible(name [, visible])`
`rs.DeleteLayer(name)`
`rs.ObjectsByLayer(name)`	list of GUIDs

Document & View

Function
`rs.UnitAbsoluteTolerance()`
`rs.UnitSystem()`	int (`rs.unit_system_*`)
`rs.EnableRedraw(enable)`	toggle this around bulk ops
`rs.Redraw()`	force one redraw
`rs.ViewNames()` / `rs.CurrentView([name])`
`rs.ZoomExtents(view=None, all=False)`

Selection

Function
`rs.SelectedObjects()`	list
`rs.SelectObject(id)` / `rs.SelectObjects(ids)`
`rs.UnselectAllObjects()`
`rs.InvertSelectedObjects()`

Macros from Script

rs.Command(command_string, echo=True) runs a macro exactly as if typed at the command line. Always prefix ! (cancel) and - (no dialog):

rs.Command("! _-Line 0,0,0 10,0,0", echo=False)
