Hey I just started working on this project and already ran into a issue. I want to connect the marked areas. I thought the Loft tool would be the right choice to do it. Thanks in advance!
Select all the faces and loft then subtract some and loft-cut.
You cannot loft a face that has a hollow area in it.
Loft tool works only with plain faces.
So either:
- you project the outline of each face to new sketches and use loft from these simple faces or
- you temporarily change all the internal lines into construction lines before doing the loft, or
- you extrude top face upward any distance, bottom face downward any distance and do the loft operation from the bottom of the top extrusion to the top of the bottom extrusion

Be nice if the loft would intuitively ignore the internal faces.
