Random number generator for grades?

[MC_Dalsgaard]

Hello,

I am making a bridge deck in Civil 3D and I am using this method described here where I create a random number generator sub assembly to control some variables in the deck with a profile line string. This has been incredibly useful, but I can't seem to get it to work with grades. I tried changing the output parameter to a grade, but no success.

Anyone know if it is possible?

I'm trying to figure out the same thing, watched that video yesterday...I'm following this post...if I figure out anything I'll post a reply..

I am sure that can be achieved. So you draw an auxiliary profile with positive or negative elevations at different stations?
And then should these elevations be used as an output value, but interpreted as a slope and assigned to  a specific subassembly?

What is it currently not working for you? Could you publish your modified number generator as PKT and a sample file as DWG that clearly shows your current attempt?
Perhaps you just have to convert the elevation into a slope by simply dividing the elevation values by 100?

This is just for intra-region transitions right? What about transitions between regions with different subassemblies? (The reason I ask is - I have a workaround in place where I needed a negative cut-slope grade which couldn't be done without adding a conditional fill (I know, sounds weird, but that was the only way to do it)). So I have two regions that I need to have a transition between. I suppose I could (if I can figure out use of the number generator) have the regions meet at a zero slope.
