IClassic

Returned by ClassicApi — the classic comfort-fit ring shank. Multiple gems possible, so no single mother gem (MotherGemId is empty). Adds to IParametricObject:

Member	Meaning
RingSizeLabel	Ring size label, e.g. "54"
RingSizeRegion	Ring size region, e.g. "EUROPE"
RingDiameterMm	Inner diameter, mm
TopProfile / MidProfile / BottomProfile	The three section profiles — IClassicProfile each
ExternalProfile	The outside-face profile — IClassicExternalProfile
Advanced	The band opening — IClassicAdvanced
Gems	The gems row — IClassicGems
SetWidth(width) / SetHeight(height)	Shortcuts for the two most common edits — same as TopProfile.SetWidth / TopProfile.SetHeight

The six section members are live views over the shank’s stored parameters: their getters read the current values and every setter regenerates the shank in place (same Guid), gems and prongs included.

from ArtisanPlugin.Scripting import ClassicApi as classic, Transaction

ring = classic.Selected()[0]
with Transaction.Begin("Slimmer band with a gem row"):
    ring.TopProfile.SetWidth(2.2)
    ring.Gems.SetEnabled(True)
    ring.Gems.SetGemSize(1.5)
    ring.Gems.SetAngle(200)

Section profiles (IClassicProfile)

TopProfile, MidProfile and BottomProfile share this surface. The top profile is always enabled (calling its SetEnabled raises); mid and bottom are optional extra sections:

Member	Meaning
Enabled	Whether this section is built (always true for the top profile)
ProfileName	Name of the RING_PROFILE asset, "" when unset
Type	How the open profile curve is closed: "SOLID", "COMFORT" or "THICKNESS"
Height / Width	Band section, mm
Thickness	Wall thickness, mm — used when Type is "THICKNESS"
Comfort	Comfort depth, mm — used when Type is "COMFORT"
Rotation	Profile rotation, degrees
Displacement	Profile displacement, mm
Orientation	0 = Natural, 1 = Reverse (flips the profile curve)
SetEnabled(enabled)	Enable/disable the section (mid and bottom only)
SetProfile(assetName)	Swap the profile — a RING_PROFILE asset by name
SetType(type)	"SOLID", "COMFORT" or "THICKNESS"
SetHeight(height) / SetWidth(width)	Band section, mm
SetThickness(thickness) / SetComfort(comfort)	mm
SetRotation(degrees) / SetDisplacement(displacement)	Rotate / displace the profile
SetOrientation(orientation)	0 or 1

External profile (IClassicExternalProfile)

The optional profile carved on the shank’s outside face:

Member	Meaning
Enabled	Whether the external profile is applied
ProfileName	Name of the EXTERNAL_RING_PROFILE asset, "" when unset
Top / Mid / Bottom	External height at each zone, mm
SetEnabled(enabled)	Turn the external profile on/off
SetProfile(assetName)	Swap the profile — an EXTERNAL_RING_PROFILE asset by name
SetTop(height) / SetMid(height) / SetBottom(height)	mm

Opening (IClassicAdvanced)

The opening at the bottom of the band:

Member	Meaning
OpeningType	"NONE", "CUT" or "STRANGLE"
CutLength / CutBumping	Cut opening parameters, mm — used when "CUT"
StrangleOpening	Opening width, mm — used when "STRANGLE"
StrangleBaseX / StrangleBaseY / StrangleBaseZ	Strangle base section, mm
SetOpeningType(openingType)	"NONE", "CUT" or "STRANGLE"
SetCutLength(length) / SetCutBumping(bumping)	mm
SetStrangleOpening(opening)	mm
SetStrangleBase(x, y, z)	The three base dimensions in one call, mm

Gems row (IClassicGems)

The row of gems the shank can carry around its band. Enabling or editing it re-bakes the gems and prongs as child objects:

Member	Meaning
Enabled	Whether the gems row is built
GemShape	"ROUND", "PRINCESS", …
GemSize	Gem size, mm
Angle	Degrees of the band covered by gems (180 = top half)
MinDistance	Minimum distance between gems, mm
Margin	Side margin, mm
Vertical	Vertical displacement of the row, mm
GemInside	How deep the gems sit inside, mm
InnerWidth / InnerHeight	Inner channel section, mm
BrightCut	Bright-cut width, mm
ProngType	"NONE", "SHARED" or "SCALLOPED"
ProngHeight / ProngMoveInZ	Prong height and Z displacement, mm
AutomaticProngDiameter / ProngDiameter	Automatic diameter, or the explicit one in mm
DrillType	"NONE", "ROUND" or "QUAD"
DrillWidth / DrillHeight	Drill section, mm
DrillAllowIntersection	Whether drills may intersect
ExtensionForManufacturing	Manufacturing extension, mm
SetEnabled(enabled)	Turn the gems row on/off
SetGemShape(shape) / SetGemSize(size)	The gem template
SetAngle(degrees)	> 0 and <= 360
SetMinDistance(distance) / SetMargin(margin) / SetVertical(vertical) / SetGemInside(gemInside)	Placement, mm
SetInnerWidth(width) / SetInnerHeight(height) / SetBrightCut(brightCut)	Channel, mm
SetProngType(prongType) / SetProngHeight(height) / SetProngMoveInZ(move)	Prongs
SetAutomaticProngDiameter(automatic) / SetProngDiameter(diameter)	Prong diameter
SetDrillType(drillType) / SetDrillWidth(width) / SetDrillHeight(height) / SetDrillAllowIntersection(allow)	Drills
SetExtensionForManufacturing(extension)	mm

String parameters are case-insensitive and tolerate dashes/spaces; an unknown value raises a clear error listing the valid ones.
