import rhinoartisan as ra

Wraps ArtisanPlugin.Scripting.ClassicApi.

Functions

Function
`all()`	`Classic` handles for every object of this kind in the active document (empty when there is no document).
`by_layer()`	`Classic` handles on the layer with the given full path (empty when the layer does not exist).
`count()`	Number of objects of this kind in the active document.
`create()`	Builds a classic ring shank (the ArtisanClassic tool, headless): a comfort-fit band at the document’s finger size, optionally with a row of gems around the top.
`find()`	The handle for `id`, or None when the id does not belong to an object of this kind.
`selected()`	Classics currently selected in the active doc.

ra.classic.all()

ra.classic.all() -> List[Classic]

Classic handles for every object of this kind in the active document (empty when there is no document).

ra.classic.by_layer()

ra.classic.by_layer(layer_name: str) -> List[Classic]

Classic handles on the layer with the given full path (empty when the layer does not exist).

Parameter	Type
`layer_name`	`str`	required

ra.classic.count()

ra.classic.count() -> int

Number of objects of this kind in the active document.

ra.classic.create()

ra.classic.create(width=None, height=None, finger_diameter=None, with_gems=None, gem_size=None, gems_angle=None, profile=None, plane=None, element=None) -> Classic

Builds a classic ring shank (the ArtisanClassic tool, headless): a comfort-fit band at the document’s finger size, optionally with a row of gems around the top. This is the scriptable way to give a design its ring body. Millimetres; omitting keeps the tool default (or the user’s saved defaults): width 3, height 2. finger_diameter 0 = the document’s configured finger size. with_gems True enables the gem row (gem_size default 1.2 mm, gems_angle default 180 degrees of the shank covered). profile picks a RING_PROFILE asset by name; omitted = the default profile. plane omitted = world XY. Returns an Classic handle to the new shank. element = name of a saved element (ra.elements.list) to start from; explicit arguments override it.

Parameter	Type
`width`	`float`	optional — None = the tool default
`height`	`float`	optional — None = the tool default
`finger_diameter`	`float`	optional — None = the tool default
`with_gems`	`bool`	optional — None = the tool default
`gem_size`	`float`	optional — None = the tool default
`gems_angle`	`float`	optional — None = the tool default
`profile`	`str`	optional — None = the tool default
`plane`	`Optional[PlaneLike]`	optional — None = the tool default
`element`	`str`	optional — None = the tool default

ra.classic.find()

ra.classic.find(id: IdLike) -> Classic

The handle for id, or None when the id does not belong to an object of this kind.

Parameter	Type
`id`	`IdLike`	required

ra.classic.selected()

ra.classic.selected() -> List[Classic]

Classics currently selected in the active doc.

Handles

Objects returned by the functions above. Assigning a settable property regenerates the object; the change is one undo step inside ra.transaction().

Classic (handle)

Classic ring shank (multiple gems possible) — no single MotherGem.

Property	Type
`advanced`	ClassicAdvanced
`bottom_profile`	ClassicProfile
`external_profile`	ClassicExternalProfile
`gems`	ClassicGems
`layer_name`	`str`
`mid_profile`	ClassicProfile
`mother_gem_id`	`str`
`object_type`	`str`
`position`	`Point3d`
`ring_diameter_mm`	`float`
`ring_size_label`	`str`
`ring_size_region`	`str`
`top_profile`	ClassicProfile	Parameter sections — each is a live view over the shank’s stored parameters; their setters regenerate the shank in place (same Guid) and call LicenseGate.RequireValid() first. Millimetres.

Method
`delete()`
`move(translation: VectorLike)`
`set_element(element: str)`	Applies a saved Classic element (ra.elements.list(“Classic”)) to this shank: its parameters replace the current ones, the ring size stays, and the shank regenerates in place (same id).
`set_height(height: float)`
`set_width(width: float)`	Shortcuts for the two most common edits — same effect as TopProfile.SetWidth / TopProfile.SetHeight.

Plus what every handle has: id, delete(), update(**kwargs), parameters(), equality and hashing by id, and raw (the underlying .NET object).

ClassicAdvanced (section)

The classic shank’s Advanced section: the opening at the bottom of the band.

Property	Type	Settable
`cut_bumping`	`float`	yes	mm — used when OpeningType is “CUT”

Method
`set_strangle_base(x: float, y: float, z: float)`

ClassicProfile (section)

One of the shank’s three section profiles (top / mid / bottom). The top profile is always enabled; mid and bottom are optional.
