About Moving Profiles
Each assembled profile is identified by the profil_ref_sys group identifier. Profiles reference a coordinate system inside the group and the features reference the curve. You can move or rotate a profile relative to the reference curve, or toggle the start and end points. You can define the position of a profile so that:
• The geometry element you select (surface, edge or vertex) aligns to the reference curve or to a geometry element on another part.
• It is positioned in a predefined location.
• It is offset by a specified value or angle.
