I don't know if I understand your original problem, you have 2 complex
curves running more or less side-by-side in your model, and you want to
make a curve that runs between them as an average, is that right? ( I'm
imagining something like a DNA spiral) How accurate do you need this to be?
What my thoughts were on this:
Create on-curve dtm points on both curves (the same ratios, you can link
them with relations) however many you need to make the curve run relatively
smooth and true between the curves.
Now you have two sets of dtm points across from each other on the curves.
Next, you can make point-to-point curves between each set of points. Now
you can make on-curve points at half ratio on each of these curves. now you
can run a curve by points, and pick each of these halfway points. That
should give you a curve that runs roughly between the two curves.
Let me know if I haven't understood correctly.
