Grading problem

[johnaa52]

I'm do grades on a road where the right sidewalk is about 2 feet higher than the left. When doing the multiple section views, the right side shows a 24% grade and the left side shows a 7% grade. I lowered the rightside as much as I dare without creating a super elevation. The curbs are close to being equal. Can I use the curbline as a featureline and will this work? If this does work, then how do I do it. Sorry for being so dense. Thank you.

I'm not 100% clear on what you're asking, but I'll take a stab at it:

Do you currently have an existing curb line, represented by a 3d polyline or feature line, and you want to use that as a target for your new curb line? If that's what you're asking, then, yes, you can do that.

Be sure that whatever subassembly you use for curb has ability to use Targets. Look in subassy help for your particular subassy to be sure. Once you confirm that and have designed your Assembly, in the Corridor Parameters for the region you're modifying, pick the Targets button. Look for the subassy you're dealing with and set its Width and Elevation targets to that feature line (or 3d poly) you already have in the drawing.

Hi tcorey

Thank you for your response. I have an existing curb but it is in pieces and only on one side. I set my curb by offsetting the ROW. My assemblies do have their targets set. I draw a polyline on both gutterlines and both streetsides of the sidewalk. If there is no walk then I offset from the ROW. I then attach my profile to the corridor, create sample lines, choosing to create by range of stations. Then I create my Multiple Section Views. This is where I run into my problem. We have set standards for minimum and maximum grades for the boulevard slopes as 2% and 8%. Is there a way to make my curb lines 3D polylines or feature lines and would that help? Thank you.

I am including a section view with the existing ground about 2 feet over the top of curb. I created a breakline from my curbline, but that did not work Thank you.

Hello again,

Can you post your drawing? That will help me determine what geometry you have and what you might need, etc.

Is it t he design intention to cut the road? If so you will need a wall behind the sidewalk, no?
