InRoads Abutment Grading

I'm not sure what exactly you are trying to do.  It looks like your contours are in correctly now but maybe those are hand drawn and you are looking to end them at the abutment.  If that's what you are trying, make the abutment an interior boundary and drape it over your proposed contours so the contours end properly.

Greetings-

I've found the easiest way to make a ramp up to a bridge is to make the bridge a seperate DTM - let the ramp dirt on either side of it be seperate DTMs.  It can be done in one surface, but I've found it's not the most elegant way to do it.  The wingwalls can be run as corridors as part of that first dtm.

Tom, I have made a step by step video for this.  Note it was done with GEOPAK but you will get the idea.  HTH.

I did a video on Gores as well...it is not perfect but maybe useful.  I made one mistake in that I should not have applied point controls until after I used the Vertical Gore projection tool.

Tom,

this was very helpful.  I wish there were more short videos like this offered by Bentley as the documentation has always lacked.  I've been trying to come up with a good way to do the earthwork (embankment and structure backfill) at abutments for some time and all of the ways I've come up with are anything but easy.  I'd like to learn to use quantity manager but I can't find any documentation on how to use it.  If you have any other videos, please post them as they help a great deal even though they are in geopak and not inroads.

While these videos are for the Roadway Designer in GEOPAK, all of the steps can also easily be replicated with InRoads.
