Loft with Centerline

How to create an object using Loft with Centerline (see attached picture)?

I can create an object using the loft with BRepOffsetAPI_ThruSections. But how do I specify the centerline? Maybe I need to use GeomFill_Sweep and set the law myself?

The 2nd image, is it.not a case of sweeping with a path curve.

The 2nd image is Loft with Centerline. How to do it in OpenCASCADE?

Loft with Centerline is implemented in all popular CAD (Solidworks, Inventor, etc.). But how to do it in OpenCASCADE?

i think BRepOffsetAPI_ThruSections is what you are looking for 

see this :

EDIT: sorry i didn't read the question well ,with BRepOffsetAPI_ThruSections we still need to generate a sequence of sections by looping the parameter U of the parameterized curve "centerline" translating and scaling the profile, sorry i don't know a better way :( I'm new to occt

I'm also new to OCC. I wrote to the author of the blog about my problem. Now you can see the solution here -

Interesting post. 

Bu this creates a geometrical surface and not a solid shape. 

Your requirement was to create solid loft ?
