Feature line grading object problem

We have what seems to be a simple task.  

 

We have a feauture line that we are creating a 4:1 cut/fill grading object (and new surface)  to an existing surface.

 

When we create the grading object, we have a segment along the feature line that has no grading or grading surface created.  

 

When we create the grading, the feature line then has "intermediate" grades created at the place where no grading occurs.

 

We have tried moving the feature line to its own Site with the grading object.  We have made sure that the feature line has no intermediate grades prior to grading.  When we create the grading, the intermediate grades show up on the feature line and the grading is "gapped" around the intermediate points.

 

Any suggestions to fix this "gap"?

 

Thanks in advance.

Are you answering Yes when it asks to apply to entire length? If so, answer no and pick the start and end of the ranges manually. Does this fix your problem?

Thanks for the reply.  I tried manually selecting the length and it didn't work.  I also tried manually picking only the problem area and it wont grade that area.  It is in an area of fill and it won't grade fill up to the existing grade.

Feature lines can be finiky.

Try drawing a new one, snapping to the one you have, and try grading from the new one...see if that helps.  No idea why it would, just what I would do.

was the feature line created from a polyline? If so, the pline may have contained pseudo nodes that could be gumming things up

Thank you

Make sure the grading parameters are such that the grading intercepts the terrain in that area. It may be that you have inadvertently applied a very flat slope or the elevations are far off the terrain so that it can't find a solution.
