SR 7001499116 Defect
There is a defect in ORD 2021 R2 and older where if you have a horizontal curve and have a change in elevation it will try to create a vertical curve between survey shots as well. See before pic. To solve this I have found you need to double code the shot as an end of non tangent and begin of non tangent for the same line code. See after pc.
You'll have to have the start curve and a point on curve shot before hand or after depending on the situation.
Since some of us are using DOT standards we might be on this version for a while. Hope this helps others in the field.
