Old school engineers and drafters still live in a world when a set of plans is a work of art and should reflect the real world. However, in the modern computing world, when finite math reaches a number, the computing stops. A great example of this is how the contours look when you are creating a corridor surface.
Contours are a major player in the older practice of hand drafting. Contours are flowing objects with few hard edges and angles in the real world. Yet when we calculate a TIN intersection the contour will just stop and make an abrupt turn where that intersection is computed without any thought to what the end result will look like. I hear this question a lot from users: “How do I make my contours “tie in” with corridor surfaces?” By “tie-in,” they mean make the swooping arcs and look like they eventually will in real life. If you follow the link below, you’ll see an example of what old school engineers don’t want to see, how to fix it, and what the end result is.
