Hi Jeff, wow that's quite a lot of stuff to digest in your post there.

It will probably be more feasible to try and focus on one issue at a time to help you.

So start with that sloped section you are talking about - you seem to be structuring your cutting surface with construction curve cross sections running in this direction:



But then are you saying that you're actually trying to match a profile that is specified in this other direction instead: ?




Is it possible for you to post the blueprint background image that has the contour line in it that you're trying to match?

That will probably be a kind of awkward task because it sounds like your main reference is a kind of skewed projection of the slope instead of an actual plan view cross section of the slope?

Do you possibly have any photos of the finished sloped piece? Does the slope actually run naturally along the given cross-section direction, or does it run more naturally along the direction that you have positioned your curves?
