I’m relatively new to working in the footwear industry, and I am trying to become accustomed to good methods and practice/order for sole construction. I feel like I’ve been through pretty much everything there is on YouTube.
One of the common roadblocks is trying to create organic surfaces that have at least some kind of dimensional control to them, rather than just eyeballing it. So the common order of work is using 2D designer drawing to get a floor/bottom curve which overshoots and creating a straight extrusion. Then creating the side walls using a thickness from the last and profiles, trimming it with the floor and applying a BlendEdge. Or another I recently found was doing a variable pipe/Sweep1 around the intersection of floor and sides, trimming away from floor/sides and then doing BlendSrf. Of course this is all done around a Last model + Upper substance.
I am trying to achieve something similar to the following: Surface modeling problems - so creating an outer surface which I can trim away from with very freeform projected curves. I’ve attached my example of a ‘base’ polysurface. Imagine that I am trying to create ‘raised zebra stripes’ that go along the bottom but also round off around the sides - So the best way seems to be the simple premise of an ‘A’ and ‘B’ surface. (Displacement is not an option here, I need to surface this).
To cut a long story short, I am trying to get a good single surface from the attached, so that I can offset neatly, trim a large patch on the A surface and an offset patch on the B surface, and then blend between to create neat ‘islands’, if that makes sense. I also had an idea of using Fin as a guide surface and blending that to the top islands. Really looking for good tips on how to Network it well to, say, 0.1 or 0.5. Having these ‘monocoque’ surfaces would also help me with FlowAlong - again I am usually restricted to just flowing along constituent surfaces i.e. only the bottom, only the swept side, only the blend area.
Attached is my really basic structure of the sole underneath the Rand area. So if i start trimming that between edges etc. it’s just making things very awkward when I get to blending surface edges.

Any words of wisdom would be most appreciated - this sole modelling stuff is really hard to pick up on your own. No man is an island! Really keen to try and hear from others who have done this kind of work for a while or are in this field of work too.
Many thanks in advance. (excuse the long post)
