Template - Not following Vertical Point Control

One of our engineers had this problem last week, but they had performed a 'corridor reattach' that caused the problem. When they changed template A to template B then back to template A all was right with the world.

If you're not seeing these problems at template drop locations, it would be worth changing the interval.

Yes! Sorry for the misunderstanding. We could try and decrease the template interval to see what happens. And to answer your questions, yes, the vertical offsets are meant to be the ditch bottoms and we are seeking them normally by using the point control command. In the point control command we selected “Vertical Offset” and “Linear Geometry” and used the lines from the profile as complex elements.

By "drop templates", I mean each location where ORD has evaluated the geometry and template. If your template interval is 50' and you cut cross sections every 10', four out of five sections could show some unintended or unexpected results due to interpolation between the template drops.

Are the point controls (your vertical offsets) intended to be the ditch bottoms? How are you seeking them?

Hello Ray,

No, there's only one template that I used here but the Vertical Offsets are chopped for this template (Following image is a snip from the profile). We tried extending the ends of the vertical offsets by a foot so the template could recognize the point. Here is what the vertical offset looks like for this cross section in question. The right line is the Right Vertical offset while the white line (That is, the second white line from the top down) is the left vertical offset. What we theorized was that because there is a break in the lines, it will mess with the template but we wanted to make sure if that is even the problem.

Are your cross sections at the same locations where you dropped templates. If you draw cross sections between template drops you will end up with results like these.
