Rhinocommon equivalent to "_fin" command (SOLVED)

Dear Community - or Dear Steve @stevebaer
can anybody tell me, if there is a Rhinocommon equivalent to the Rhino _fin command.
http://docs.mcneel.com/rhino/5/help/en-us/commands/fin.htm

i know there is a workarround Rhinocommon Curve.OffsetNormalToSurface Method
https://developer.rhino3d.com/api/RhinoCommon/html/M_Rhino_Geometry_Curve_OffsetNormalToSurface.htm
and this can be combined with loft
https://developer.rhino3d.com/api/RhinoCommon/html/M_Rhino_Geometry_Brep_CreateFromLoft.htm

thanks for a short hint / yes or no / or a better workarround
all the best - tom

Hi @Tom_P,

The Curve.OffsetNormalToSurface function, which you’ve referenced, provides the functionality behind the Fin command.

Is there something else you’re looking for?

Thanks for the fast reply.
