Quick Profile from Surface/ Intersecting Corridors

Sorry, I meant to say that the snap cannot be persisted to 3D Cut graphics. If the 3D cut is updated due to a design change then any geometry that was snapped to 3D Cut graphics will not update (move) with the change.

Honestly, Steve, I just don't think it ever occurred to me to use Quick Profile From Surface with the Corridor as the surface object. You've piqued my curiosity! Always so many ways to do things. The situation I and my "hydro" clients often discuss is designing "special cut ditches" that are intended to modify the standard cut ditches generated by the corridor models produced by the "roadway" teams. So, we are dealing with referenced corridor models that they don't control or even access. The goal is usually to develop horizontal/vertical geometry which is then used by the roadway teams (as Point Controls) to modify their corridor models to incorporate the desired ditch revisions. So, using a 3D cut has been a handy way to "see" the corridor model and use it for ditch design purposes. I'll have to think about Quick Profile From Surface and play with it to see what advantages it may provide, particularly if I want to create some graphics/geometry directly from the corridor that I want to retain, rather than just reference. Thanks for the food for thought, as always.

I have used/ tested this concept. The huge advantage is time. These 3D cuts are very processing intensive, so it is nice to be able to trace the 3D objects and then remove the cut.

Karl, this is good to know, I haven't tended to use the 3D, but nice to know we can. Is there any particular reason or advantage you see to using the 3D cut over the sampled top mesh? You've piqued my curiosity.

You most welcome. Glad you got it figured out.

Hi Paul

I have found that I can snap to 3D cut graphics, but I always have to enable snaps in the Reference dialog first because it seems to always be off by default. I will frequently create profiles by snapping to corridor graphics generated by 3D cut.

This is exactly what I was looking for. Thank you for your response!

Melanie,

Yes, my corridor is referenced in. A few things to try/check if it is not generating the surface. 1.) Sometimes the software doesn't seem to read in all the 3D data when first referencing files with Corridors or Civil Cells, simply reopening the file is sometimes sufficient. 2.) Confirm that the managed 3D model has been created. I don't believe simply opening a profile view will do that, you will need to set a terrain or profile active. 3.) If you are starting the command from the Ribbon, be sure that you are selecting what the software is asking for. (A lot of my students get tripped up by this.) "Locate Reference Element" is looking for the alignment you would like to profile the surface for while "Locate Reference Surface" is looking for the Corridor. I select the Corridor Handles for that as it is possible to select the Component meshes as well.

Is your corridor referenced in or actually in your drawing? This is what I want but I get the "Element is in a read-only reference" when I hover over it and it won't let me select the corridor.

Melanie,

I use the Quick Profile From Surface with the Corridor as the surface object. This gives me vertical information as well as mainline cross slope and the opportunity to use that in a number of ways to start my profile and leverage design intent.

Hope that helps!

Here are two options:

Profile Intersection point https://www.youtube.com/watch?v=v-aQFSEr_bk

3D Cut https://communities.bentley.com/products/road___site_design/w/road_and_site_design__wiki/41757/video-create-3d-cut-in-profile

Note that the graphics shown in the 3D cut cannot be snapped to for new design elements.
