I created a new field book and imported a text file with survey points. after importing and cleaning the linework and points i noticed that any curves that were drawn have a vertical curve/spline forced into them.
instead of holding the elevations of the points in the feature, the curve dips above and below where it is supposed to be. (see picture below)
it is supposed to be a curved top back of curb feature line. is there a setting in microstation that will stop this from happening?
CURRENTLY USING "cadd Power GEOPAK V8i (SS4) with openroads.
thanks,

I noticed this with InRoads Survey. We could set up filters to use when writing Survey to Graphics and would use them to write some that splined horizontally and vertically, while others were only splined horizontally. In my Tests of Opened Roads Survey, I did not see any such options. I have pointed this out but have not seen or heard anyone from Bentley address this. There are many places in InRoads and GEOPAK where we had control that now is trying to use a standard MicroStation setting and this is not an improvement. Using configuration variables is no where near as convenient (or flexible) as having dialog boxes with settings.

Has anyone found the fix to this issue? If it was only in the depressed curb areas, I might be able to deal with this. It happens in curved sidewalks, roads, tops, toes, etc.
i have yet to find a reason why microstation does this, the only fix i can provide is changing/messing around with the curve codes in the chain or adding calc points based on the elevations of the chain along the chain itself, adding those points into the chain, then removing the curve code so that it basically looks like a curve but is just straight lines
It does this because it is fitting a curve between points vertically as well as horizontally. In prior versions, when you wrote to DTM or Graphics, you could specify to only stroke the curve horizontally, or only vertically or not at all. And since you could apply filters, you could isolate those figures that give the software a problem.
We did start having our crews shoot extra shots and once we explained the issue, they had no problem with the extra work.
Still, there needs to be more options in OpenRoads to match some of these earlier version options.
