-
From the
Road
and
Railway section of the
action bar,
click
Vertical Alignment
.
-
Select the horizontal alignment you want to work with in the
Vertical Alignment Creation dialog box.
-
Optional: Click Bounding box width
to refine the display of some objects you want to transfer on the
vertical sketch.
-
Under Transfered to vertical alignement, select a
terrain.
-
Select geology and layers.
-
Select other 3D objects (for example buildings).
-
Optional: For the layers or 3D objects, select the
visualization mode of your choice.
-
Optional: Under Output Management,
select the objects for which you want to generate an output if not
already selected. The outputs will be generated during the creation of
the 3D alignment.
-
Click
OK.
-
To edit the simple/compound/reverse curves one after the other, use the
navigation arrows
on each
side of the Name box in the Vertical
Curve dialog box.
Recommendation:
Clear the Distorted scale
option, otherwise the zoom on the curve cannot occur during navigation.
Notes:
- A reverse or a compound curve contains more than one curve. It is,
however, considered as a unique curve during navigation. In this
situation, more than one curve are zoomed in.
- The left or the right arrow is disabled
when:
- you get to the first or last corner of the alignment.
- there is a corner with only a point, without any spiral and
tangent.
-
To replace sag and crest curves with arcs or parabolas between two lines,
select an existing vertical curve and click Vertical
Curve
.
-
Choose a curve type in the Vertical Curve dialog
box and select Arc or
Parabola in the list. The choice is also
available in the Curve Creation command, in the
Alignment assistant.
You can keep this choice for the rest of the vertical curves you will create or change
it at any time. Parabola is the default value. Depending on your
selection, the curve is blue (arc curve) or orange (parabola curve) in
the vertical alignment. The preference is stored and managed in the
RoadAlignmentDesign.xml or RailwayAlignmentDesign.xml in Data Setup, for
road/railway design. When you define the value to "1" for arc and, "2"
for parabola on the Vertical Curve Type line, the list displays the
selected value: arc or parabola. You can change the curve type during
its creation and the preference is no longer taken into account.
-
Enter a Length value in the
Parameters section of the Vertical
Curve dialog box.
- Optional:
Use design rules:
- If there is no design rule, a warning message is displayed in
the dialog box saying that there is no minimum and maximum
defined value.
- If the design rules are retrieved, a message appears with the
maximum and minimum defined values. The range of the length
parameter editor is updated accordingly.
You can read the Measures of this type of curve in the
same dialog box. Parabolas provide smooth transitions in design.
-
To prevent the creation of additional or inconsistent arcs when you create or
upgrade an alignment, the administrator can customize arc length boundaries in
the xml resource file named Alignment Design Rules located in
startup\Civil\AlignmentDesignRules , from the Data Setup.
When you create an arc, the Minimum/Maximum length parameters are locked: the
value is retrieved from the design rule file and you cannot change these
parameters manually in the user interface. You need to edit the xml file,
called Alignment Design Rules, located in
startup\Civil\AlignmentDesignRules .
When the boundary values are initialized in the xml file, the Min
length and Max length parameters
appear in the tree under the Arc node with the icon . This
icon is displayed when a Minimum/Maximum length of the arc, without formula,
has been defined in the xml file. The Minimum/Maximum length of the arc is
locked. Therefore, its value is updated automatically and you cannot change
it unless it is unlocked.
Select the Min/Max parameter and click the Unlock
contextual command, to modify the value of the formula if it exists. When a
parameter is unlocked, the following icons appear in the tree:
when the Minimum/Maximum length of the arc is unlocked and not
restricted. You can change the length values manually.
when a formula has been defined in the xml file. The parameter is
unlocked, you can change the formula manually.
Notes:
- More generally, Minimum/Maximum length constraints are created along
with arcs, preventing complementary arcs to appear, inconsistent
configurations (reverse/intersecting arcs). The constraints are not
visualized in the 3D area and the tree. You can only see them in the Sketch
Analysis tool. When the arc radius constraint is
deleted, Min and Max constraints are not guaranteed on the arc.
- Horizontal alignments created before R2021xFD02 must be upgraded to
benefit from this function.
-
Click
Create Profile and create the profile along
the horizontal alignment.
-
To create a point based on stationing, click
Point
.
-
From the
Alignment section of the
action bar,
click
Switch Points
to switch from a vertical sketcher point to a typed
alignment point, on a terrain in a vertical context.
With this command, you can give a semantic type to the alignment points you create.
It allows you to adapt to the terrain topography and differentiate these points
for each construction type (bridge, dam, ground, tunnel). In the
Switch Point dialog box, you can define:
- The Label: A new keyword,
%t, allows you to add a semantic type.
- The semantic Type of the new alignment point:
Bridge, Dam,
Ground (for natural terrain level), or
Tunnel. For example, you can create two
alignment points to locate a bridge.
Then select a point, it is automatically typed and, a flag containing
the information is displayed on this point. To remove the semantic
typing on the point, click the Eraser icon in the label. You can
select another point and repeat the process.
-
Click Check in the Alignment
Assistant to verify your design.
-
To fix errors, right-click them in the
Messages Reporting, and select
Fix Error.
-
To display the stationing after exiting the sketcher, click
Stationings
from the
Civil Engineering
section of the
action bar
and click
Display vertical context.
In the Stationings panel, docked to the right,
Display commands are available.
The vertical alignment is created.
