Hello,
I have a divided highway in two different corridors (east bound/west bound). I have a median ditch in the center. I would like to somehow find the intersecting points of both slopes to create my ditch. I have created two separate models and used target aliasing in one corridor to show me the slope of the other corridor as shown in the pic below. Is there any way Geopak can find the intersectios of the two slopes?
What version of the software are you running? I am really only comfortable with Ss2 and earlier right now.
With target aliasing, you can get a corridor to attempt to tie into a design surface before tying into the existing surface.
I am pretty sure there are some videos on the workflow out there.
My problem is that I don't get to use this software on a regular enough basis and even when I do, I don't always get to use all of its features. So on the projects I have used the Roadway designer on, I have only used target aliasing once or twice. And of course I am an old school InRoads guy so I have way more experience with the Roadway Modeler than with the Roadway Designer

I am using SS2.
I googled target aliasing inroads and it returned the PDF from Colorado DOT. This link is the TOC to all of their tutorials. It has zip files with the data sets.

That same google search returned video links and some pages in these forums. As I said, I have used target aliasing successfully in the past. But to try and talk you through it, I'd have to dig up those projects, re-learn its workflows before I could share the knowledge - with this, you will have worked through an example before I can even locate and re-learn the tool.
(It took three tries to get this link working.)

Thanks CADDCOP, I went through the material and it somewhat worked. In target aliasing I brought in both my corridor and proposed surface. It will not target the corridor but did target the surface. The only problem is, is when the proposed surface came in, the top of pavement looked correct but the slope was not a perfect 1:4 like in my template or in my corridor. So I don't know why it is not a perfect 1:4. I also tried Daniels suggestion with no success. Can someone from Bentley chime in? Thanks for the help everybody.
If the two corridors are not perfectly parallel, the slope for one will be correct, but the other will be skewed. Also, it is also possible that the resulting slopes will not retain their original triangulation resulting in triangles that cross multiple template drops and often the resulting slope is different than if the triangles formed along each template drop. When this happens, adding longitudinal breaklines will force the correct triangulation.
