Grading surface inconsistent

[Anonymous]

My grading surface is inconsistent, what am I gonna to do to fix that? Thanks!!

Probably have unnecessary elevation points on the feature line

Most likely what Joe said, try weeding it out a bit. Similar errors would happen....well, imagine a strong horizontal curve and a long grading (longer than the radius), grading obeys rules if it can, and it all gets crossed in and messed up, get some holes and whatnot 😉

just clear it up a bit and re-do.

Thanks Joe,

HOWEVER, if I delete some points, such as PI points, the curve won't be smooth. It may lose accuracy.

If I move up the created grading surface for 1 feet, it will show up correct. However, the surface will float up above the existing surface

Thanks IGI, would you mind to indicate me more details. Thanks

When I move the grading surface up or down for a distance, it will all show up right. Only right created on the feature line with the elevation of the surface, the surface would show like patches.

though the display is inconsistent, may I ask whether or not the cut and fill volume number is correct? Thanks

Did I say Judicious? I meant to.

can you post you file? or just the feature line?

[Joe-Bouza]

If you are grading from a feature line with elevations extracted from a surface more then likely you have morethen you need. Additionally, the horizontal geometry to the feature line - what is it? Was it created from some sqiggly line or is it a true engineered line with curves? If your grading on the inside of a curve the geometry of the curve is important.

Gradings only know that you want to go so far and such and such.... we have to determine the design viability by verifying the geometry works with the request to the grading.

post your drawing. otherwise its all conjecture

you should post the file, and tell us what's your aim 🙂

Also, sometimes it works (for someone) to draw a manual feature line on grading hole ends, in a manner that would CLOSE the hole. Then - grading infill.

It's better practise to go about the origin geometry and rules, but sometimes this is good enough.
