I have an ORD horizontal alignment with a curve/tangent/curve/tangent. When one of the curves is made larger, the adjacent tangent should decrease to zero and result in a reverse curve. Instead, I get a false line with an error that the overlap needs to be fixed. This alignment is a complex element made up of open roads lines and arcs. Thoughts?
What rules have you used to create each component of your complex element? If you want to create a reverse curve, why have you inserted the tangent between the two curves?
I created the alignment when I thought we’d have a tangent, but now we’re revising the design and making the curve larger which essentially removes the tangent. I placed the curves using the arc between elements, so I’d think the rules are good. My problem is that if I have to recreate my alignment, it’s going to cause a bunch of rework to recreate a corridor. I heard we can now reassociate a new alignment to a corridor, so I’ll explore that, but am fearful it’s going to get corrupted. I was hoping the horizontal alignment tools were a little more robust to solve overlap issues.
If you have created the arc using the arc between elements, you cannot suddenly make one of the connecting elements to disappear. You can try redefining your horizontal geometry or use the "reattach corridor" tool which works pretty well.
There are several different approaches you could take. I think I would use the Complex Redefine tool since you are replacing curve-tangent-curve with curve-curve.
