Function projectProfiles

projectProfiles(
    profiles: ProfileEntry[],
    plane: SectionPlaneConfig,
    depths: ProjectionBandDepths,
): DrawingLine[]
Project profile polygons into 2D drawing lines, classified into the construction-projection bands.
Parameters
- profiles: ProfileEntry[]
  Profiles from IfcAPI.extractProfiles().
- plane: SectionPlaneConfig
  Section plane (axis + position, or custom).
- depths: ProjectionBandDepths
  Below/above projection-band depths (world units, both > 0).
Returns DrawingLine[]
DrawingLine[] with category: 'projection'; overhead lines carry visibility: 'hidden' (dashed downstream).
