OpenRoads Designer – Rapidly Model with Design Intent


How does OpenRoads
Designer manage changes within the design model? OpenRoads Designer and the
modeling technology that underlies it really takes advantage of some innovative and
unique tools and methodologies. We like to call
it Design Intent. You might ask what’s
Design Intent? Design Intent really is a system
of rules and relationships that are captured and stored as you design and as you
create elements within your design model. Now the importance of these
rules and relationships are that they remember how you created them so that as you make design
changes as things need to change throughout your design process, those relationships
are maintained. That makes, making changes and
taking into account things that change throughout the process much more effective
and efficient. Take a few minutes with me and
let’s take a look as we explore how Design Intent or the rules and relationships in OpenRoads
Designer make modeling easier and more effective. Let’s start off by highlighting
the true power of Design Intent by using what we call a Civil Cell which is the epitome
of efficient and effective relational modeling. In this example, I’ve selected
a T intersection civil cell from my library of civil cells and now I’m defining the
elements to which it’s going to relate to in my project, in my roadway corridor. So, as I place that civil cell
element, I select the particular elements that I want it to relate to, to define its
placement within the model and then the model updates. You can see that T intersection
has been placed within our design model and it’s been placed in relationship to
the mainline corridor as we defined it when we placed it. Now we can modify the view, we
can change from a transparent to a smooth view if we want to get a different perspective
and change the view of that intersection. Now, what happens after
placement of an element? So, let’s look at modifications. In this case, we’re going to
look at the secondary alignment and I’ve opened up the profile window of that
secondary alignment. You’ll notice I select
the alignment that there is relationships and definition to that profile alignment. Relationships have been defined
along that profile to the pavement cross slopes of the mainline. So, as we move the horizontal
location of that intersection, notice the profile view. The relationship between the
profile of the secondary road and the pavement slope of the mainline is maintained
because of our Design Intent. So, as we relocate that
intersection, the integrity of the intersection is maintained. We can go back, we see
that relationship has been sustained within our model. Now, what happens again in
another instance where we modify the profile of the mainline roadway. I’ve opened up the profile of
the mainline roadway and here you can see I have selected it and I’m simply moving
that profile around. You can see it in the
3-dimensional model as I move it around. Now, what will happen to
our intersection when we make that modification? So, as I place that or make
that change, notice the model in the side slopes changing. Now, as we continue let’s lower
the profile and see the change. Ultimately, because of our
Design Intent, the integrity of the intersections are maintained even with major modifications
as we saw in this example. I hope you were able to see the
power and efficiency that taking advantage of a rules-based modeling system and the
relationships that you’re able to impart to your designs with OpenRoads Designer makes
modeling and making changes to the model much more effective and easily. Thank you for taking
