## Can you create a side slope with radius?

I've been using the side slope function to create curbs. We have a lot of projects in our area that use asphalt berm. It has a small radius on the top. Is it posable to create a side slope with a radius?

No, curves are not possible at this point when using any commands that build perpendicular to a reference line. I have asked about this a few times over the years.

this would have to be a manual linestring creation.   Just create the desired amount of linestring to create a curve then import into the corridor.  my rwo cents.  if it is to small for grade control to cut.  best to leave it for survey to layout.

Depending on what you are doing, vertical design may be a good alternative. I use this quite a bit and leave side slope for slope tie in.

I've never used vertical design.
I'll try it.

The main reason I would like to see this supported at some point is for large slopes on highway projects.  They are not a small detail, like a berm, they are big enough to affect quantities on a takeoff and make automatics impossible. See attached example.

Aaah. I miss read this I thought this was referring to the curves in the horizontal not the cross section. I definitely agree. I have also had the need for a parabolic surface.

Vertical design would work for curb berms but I don't think it would work for what you want Nelson without a lot of manipulation. I cannot say I have tried though because that is the first time I am seeing a detail like that.

I have used Multioffset for other situations like this, pipe, and it works great. You would just have to determine you chording.
