Hi ChrisFC, greetings to the Community!
Is this what you want to achieve?
If your answer is "yes" then I advise you to transform the two lateral ones into Sketch (making them completely alleyways), create a Body in Part Design, then transfer the 3 Sketchs inside the Body and finally proceed to the "Loft" function by Part Design ".
Hi domad!
Firstly thank you for taking the time to help with this. This is close to, but not exactly what I am after. See, in reality, I have a large block that overlaps the model that you show. By connecting a circular arc on either of those leading edges as I described, I had planned to make a conical surface between those 2 circles. What you have created with the loft is very close to this, however, my plan is for said conical surface to be extended beyond the periphery of the present model you show, such that I can us it to cut away at the aforementioned larger block. Ultimately these end faces that I provided are guides in helping the creating of the circles bounding said conical surface. The top surface you have produced would in reality be only a part of said conical surface

Here is a picture to illustrate. My ultimate goal is to use said circle through those end corner points to define an extended conical surface that would shape the black block as shown; those end faces provided are the necessary geometric guide to creating said circles. In actuality, I would like to also create another thickness parameter on the opposite side of the central cross section also, such that the radius of curvature of the inner and outer circles would be different, in turn changing to angle of the conical surface bounding the 2 surves.
Sorry if I hadn't explained the problem well at the start. What you have shown so far has been extremely useful. I had some questions following up on what you have shown if that's ok?
1. Would a sweep not be more appropriate than a loft here, or are they acting in the same way? and if so, is the loft/sweep rotating about the Z axis or some other axis?
2. Whenever I click on the Convert between draft and sketch objects button in the Draft workbench, in order to change those end faces into sketches, I keep getting the error:
Code: Select all

nobj.addGeometry(DraftGeomUtils.orientEdge(
TypeError: Unsupported geometry type: Part::GeomHyperbola
preventing me from doing so.
3. What is a 'complete alleyway'?
4. Is it possible to define a circular arc by 3 points in a sketch, wherein 1 point is in said sketch, and the other 2 (end) points are in an external geometry? I'm just thinking if there is a way to not have to make the end points sketches, but to still use the relevant corner points in them to produce said circles.
Cheers and many thanks,
Chris
