Open Profiles Trimmed by Existing Material

Initial Profile (in black) and Center Curve (in red) Resulting Rib

The rib is obtained just by extending its open profile onto existing material.

Open Profiles with No Trimming Material

If the rib cannot be trimmed by existing material, the only way of obtaining a rib is by using the Thick Profile option:

To create this, thickness has been added to each side of the profile.

Merge Rib's Ends

The Merge rib' ends option trims each extremity of the rib to existing material, starting from the profile position until the first limit encountered on existing material in each direction.

In the following example, the blue rib is created using Merge rib's ends. The profile (a red circle) swept along the green center curve is trimmed on each direction to the first faces encountered.

Merge Ends

The Merge Ends option is to be used for thin ribs (or slots). It trims a set of profiles to themselves while trimming them to existing material too.

If you consider this initial sketch composed of two curves:
