Hello,
Something weird is happening in a profile i'm producing:
When i measure on autocad my profile elevation, in a station wich hits a vertical curve, it gives me a value slightly different from the value written in the profile band.
This only happens on all vertical curves, the grades are correct.
Can it be a vertical curve type difference between the band and the profile creation? never happened to me...
Thanks.
I've just realized that in the exported autocad file, the vertical curves are converted into polylines, for sure the little difference between what i measured and the elevation value text is due to that reason. Big fail!
Is there a way to export the circular vertical curves as an arc (with no distortion profile scale)?
Thanks.
Have you mathematically verified the elevation along the vertical curve at that station point? I think the profile band elevation is correct on the calculated value. This is how I've always verified my vertical curve elevations between PVIs. I also noticed that Civil 3D will approximate curves on a profile with polyline segments. It would be difficult to use a smooth curve, since a circular curve with any vertical exageration would need to be drawn as elliptical. Even with no vertical exageration, I think Civil 3D just defaults to tesselating the profile curves.
