First Road created. Check

Now See if I can now manipulate the Slopes.

Any luck at your end, Case?

Well.....

Back looking at the Created road (Before any Manipulation), and because I set the slope angle to 33-degrees for any possible fill angle, AT seems to have created a "Fake" Fill and the corresponding contour lines at that angle. Even though not digging or embankment is required.

not a big deal to have a imaginary cut or fill line below the Mesh that is not seen, but because it effects the Contour Tool Object associated with the Mesh., this is a problem.

I gave this a try this morning with two applications noted in the screen shot. Would you agree that the slope extension can't be the same? The first time I tried it the S.E. were both 4" and didn't work. However, I got it to work with different numbers. See image. Any thoughts?

here is another example

Case, I think like myself you are not quite understanding the slope Extension and what it's uses. As far as your screen shots, I do not see enough grade change with the road location to see a need for a slope extension. I will send via PM a e-mail I received from Fabrizio about the slope extension. I am still a bit unclear, but he is always great in trying to make thing right.

I do not know what you are trying to use the S.E. to accomplish. If you are trying to change the slopes and grade of the road surface I believe that you can raise the road objects nodes in the 3D window. I usually raise the nodes using the Longitudinal section and Rebuild the Mesh.

Yes, I am unclear as well when it comes to the S.E. My site is 2459' long with only a rise of 30' ± the entire length.

Again on a mesh as "flat" as this one appears, I do not see that you will see any Diggings or embankments no matter what value angle they are set to.

As far as the middle of the road getting "filled-in", I would be curious what fill lines you are using as your road ends. this Circular type of road may have to be at least two different segments (Fills). In my previous post you can see that I have broken my road way into segments, Orange fill color and 'green' color. I also previously had fillet radius' at almost all of the corners. The curved sections are not represented properly in the Longitudinal Section, so for the most part for now I have decided to model the Roads with sharp 90-degree intersections with connecting roads. This is not real life, but AT is a nice tool for what I am doing. For proper coverage calculations and 2D representation I have a fill that represents the Rood surface and this fill will show the proper radius intersections. I would like to send you a few other copies of e-mail questions that I have for Cigraph if you do not mind. PLease send me PM with e-mail address. Or I will do the same.

I applied a 90º cut on two of the sloped angles and got this.
