Grading to surface question

[Srana123]

I created a grading of a road, curb, and tie in to existing. Road and curb are fine. I have defined the top of curb with a feature line and I just needed to grade from this proposed curb height back 2% and tie into the existing land. I used the grading creation tools and did Grade to Surface, chose EG and set my grade to 2% for cut and fill.  In the screenshot, I showed my grading settings and showed part of the section view. The green line is the proposed and existing is the red dashed. Measuring the grade, it shows as 2.5%. Why isn't this at 2%? Anyone know how to fix this?

I also noticed changing the fill slope projection grade number doesnt seem to change anything. Changing the cut slope projection seems to change the section. Since proposed will be higher than existing, i thought the fill slope projection grade would be the number I'd be changing. Can someone explain that to me?

A little direction navigating the file wouldhelp? which site? which grading group? where on the plan?

For starters. the gradings use the standard style which is set to all elemts off. there are several errors in the files when recovered and thousands of regapps. Not that theses a re cause of any prolem but it is a good idea to constantly audit and purge a grading drawing as they can be very finicky

I only have one site (Site 1) on this plan and just one grading group (Grading Group 1). I took sample lines at 1 foot intervals and made section views for that and it looks like the 2% isnt met anywhere

once you purge audit purge turn on all your layers in the current drawing and set the standard style to display I found for grading . the ones to surface eg 2018 all I did was switch to fill first and they updated. There is on on the lower right side of the site that uses a distance criteria. this one has internal conflicts where it is grading into itself.

In one of the grading tutorials they demonstrate how to normalize a feature line to apply a grading that will not collapse on itself. basically offset your feature  at your slope for an arbitrary distance and then filet the bends out, apply the grading to the normalized line and infill between the two to complete.

I just went back and inspected this again.  the line you have the projection grading on is in the same site as the line at the limit of the red contours. that gets  NFGX2 😂

Check again your drawing has multiple sites and multiple grading groups. Like I said set the standard grading style to something that displays and you will see them.

yes at the perimeter you are in a few meters of cut and fill

lol

I replied to the wrong post. Pardon
