Join Josh Modglin for an in-depth discussion in this video Profiles, part of InfraWorks 360 Essential Training.
- [Narrator] In the last two exercises we created our local road design, which contained horizontal alignment elements, tangents and curves. And then we added some grading controls to our side slopes from the edge of our assembly. We had a four to one for our fill and two to one for our cut. We're going to now adjust our vertical design by making adjustments to the road profile. So notice the proposal I'm in is RoadProfile_Start.
We're going to of course add a new proposal. And so I'm going to come down to add. And we'll name this "RoadProfile_End". And then we're going to select that road. And of course our card comes up and provides us all different kinds of controls such as the style of a road is, our geometry. Now when we select geometry of course what we see is our horizontal geometry but if I right click on the road notice there's a few other controls such as show profile view.
So we're going to show profile view. It opens up down at the bottom and of course you can adjust the look and feel of that profile view. You can also change the vertical exaggeration, so maybe we'll see it to ten to one. A little easier to actually see the design. It might even be a little bit too much so we'll do five to one. And I'll just pull this up a little bit so I can have a little bit more space as well. And notice I also have this checked to auto update so as we make these changes you'll see the changes automatically update on the screen.
So what we're going to do, we're going to slide this PVI back a little bit and as normal we're going to come off the main road at negative ... Oh we'll say roughly negative two percent and we'll place this ... I'm going to slide this a little bit further. We're going to place this PVI roughly right in the middle of the low point there. Remember there's a low point that kind of runs through here. And then we a bit of a high point and five to one still not working out so I'm going to do two to one.
The less vertical exaggeration the harder it is of course to line up and get our grades right but I'm going to slide that PVI and we'll maybe set it to something like ... That's a little high so we'll pull that down. And I'll pull it over just a little bit and we'll set it to somewhere around like two percent there. And now we still have a lot of cut and we can add additional PVIs or we could reduce.
We're going to add a PVI over here though that's for sure. And because we're not going to come into or tie back in to the main road here at eight percent. So we're going to right click on our profile and choose to add PVI. It adds a PVI roughly where we picked and I'm just going to pan back over there. And I'm picking the triangle and it slides that PVI so we're going to slide it up and we need about 50 feet roughly at two percent.
So I'll slide it up and there we go. So we have all of that and notice now I have a 10 percent fall through here and so a lot of cut. Well I don't know exactly how much cut and fill I'm working with but there is a means to do so. And we're going to make some adjustments to the profile after we've been able to do a preliminary cut and fill analysis with our design in our next exercise.
