IAdvancedCathedral

Returned by AdvancedCathedralApi — like the classic cathedral, but the band’s cross-section is defined by editable stations along the arm instead of one fixed profile. Multiple gems, so no single mother gem. Adds to IParametricObject:

Member	Meaning
RingSizeLabel / RingSizeRegion	Ring size as label + region
RingDiameterMm	Inner diameter, mm
Shank	Stations, arm and bridge — IAdvancedCathedralShank
Gems	The pavé row — ICathedralGems, the same section as the classic cathedral
GemGradient	Stone-size and prong gradient — IAdvancedCathedralGemGradient

All three sections 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, prongs and cutters included.

Band and arms (IAdvancedCathedralShank)

Member	Meaning
SharedProfile	Every station uses the same profile asset
Stations	The per-station sections — IAdvancedCathedralStation each
ArmHeight / ArmOpening	mm
TipInclination	Inclination of the arm tip
TangentPoint	1 = 90 degrees, 0 = 140, -1 = 190
TipRound	mm
BridgeEnabled	Whether the bridge is built
BridgeWidth / BridgeThickness / BridgeFillet / BridgeDiameter	Bridge section, mm
BridgeAngle / BridgeOpenAngle	degrees
SetStations(stations)	Replace the whole list (at least 2, positions 0..1)
SetStation(index, position, width, height, profileName=None)	Edit one station in place
SetSharedProfile / SetProfile(assetName)	The second applies one RING_PROFILE asset to every station
SetArmHeight / SetArmOpening / SetTipInclination / SetTangentPoint / SetTipRound	The arm
SetBridgeEnabled / SetBridgeWidth / SetBridgeThickness / SetBridgeFillet / SetBridgeAngle / SetBridgeDiameter / SetBridgeOpenAngle	The bridge

A station (IAdvancedCathedralStation)

Member	Meaning
Position	0 = arm tip, 1 = ring bottom
Width / Height	Section at that position, mm
ProfileName	RING_PROFILE asset name, "" when unset

Stone gradient (IAdvancedCathedralGemGradient)

How stone size and prongs vary along the gem run.

Member	Meaning
Enabled	Whether the gradient is applied
Points	2 = start/end, 3 = start/middle/end
MiddlePosition	0..1
GemSizeStart / GemSizeMiddle / GemSizeEnd	mm
ProngGrow / ProngMinDiameter	mm
EndProngCount / ProngSpacing / ProngDistance	Prong layout
SetEnabled / SetPoints / SetMiddlePosition
SetGemSizes(start, middle, end)	The three sizes in one call, mm
