Cut profiles and cross sections at user defined intervals along an
alignment. Define and
display proposed profiles along with vertical curves. |
|
 |
|
 |
|
Define and apply roadway templates to the cross sections.
Define backslopes or pin to an offset.
Calculate cut and fill volumes based on average end areas. |
|
 |
|
Create or Open a Road Project. |
|
Once you name a road project, you can cut an existing profile or
existing cross sections from an alignment (polyline) of your choice. The
purpose of the "Project" is to keep track of files relating to a
particular alignment. |
|
Extract profile from tin. |
|
You will be asked to select a polyline alignment. A profile will be
extracted from a TIN of your choice. This TIN must have been created
with our DTM module. |
|
Import existing profile. |
|
This command will import the profile that you extracted in the above
command. The dialog box for this command allows you to set the precision
for the existing profile as well as the proposed profile that you may
wish to import. A fully annotated grid will be placed around the
profile. A user coordinate system (UCS) will be created with the same
name as the profile. You can set this UCS current and use the section
tools command to draw and label objects in the profile. Make sure that
you have the correct scale set in the section tool dialog box. |
|
Define proposed profile. |
|
A dialog box will appear alowing you to enter PI stations and elevations
and vertical curves for your proposed alignment. The grades are
calculated and shown in the dialog box for your information. You may
enter a station and grade and change the following elevation. |
|
 |
|
Import proposed profile. |
|
After setting the existing profile UCS current, use this command to
import the proposed profile. The proposed profile will overlay the
existing profile.Vertical curves, grades and tangent elevations will be
labeled based on the settings provided when you imported the existing
profile. |
|
Set profile UCS current. |
|
Allows you to pick the UCS you wish to work in. |
|
Define template. |
|
You may define a template for your roadway. A template is a cross
section of the proposed road including the foreslope. If the template is
symmetrical you only need to define the left side of the centerline. |
|
Each surface of the template must be a polyline. First you will be asked
for a file name. This is where the template definition will be stored.
Next you will be asked to select the profile elevation point. This is
the part of the template that will be controlled by the proposed profile
(usually the centerline crown grade). If you are using proposed top of
curb grade, you must project this point to the centerline. |
|
Now select a surface of the template. You will be asked for a surface
name. If the surface is not symmetrical you will be asked to select the
right side. |
|
 |
|
Continue to select surfaces till done (see illustration). |
|
 |
|
Now you will be asked to select datum points. Datum points are required
and they define the lowest part of the template. Cut and fill volumes
are calculated between the datum surface and the existing surface (see
illustration). |
|
 |
|
Import template. |
|
Select a template file to import into the drawing. |
|
Template locations. |
|
A dialog box will appear allowing you to enter the start and end station
along with the template file to use. |
|
 |
|
Extract sections from tin. |
|
Select a polyline alignment. Enter a start station. Enter an increment
to cut cross sections along (such as every 50 feet). Now you can enter
any extra stations that you would like a cross section cut at. When done
entering extra stations press enter. Now you will be asked to enter a
left swath width. This is the distance left of the alignment that you
wish the sections to start. Now you are asked for the right swath width.
This is the distance to the right of the alignment that you wish the
cross section to extend to. |
|
Import existing sections. |
|
Use this command to import the existing sections that you extracted
above. |
|
Define slopes. |
|
A dialog box will appear allowing you to enter station ranges and
backslopes to be applied to the templates. If a slope will not work then
the template is closed upon the the last point of the existing surface.
You must be sure that your existing surface extends far enough for your
proposed template and slopes. |
|
Process sections. |
The templates and slopes are applied to the existing sections.
Before processing sections you must do the following:
Extract existing sections.
Set template locations.
Define proposed profile.
Define slopes. |
|
 |
|
Import proposed sections. |
|
Use this command to import the new cross sections showing existing and
proposed surfaces. A dialog box will appear allowing you to set certain
parameters. You should set the grid width to enclose the cross section.
You may set sheet height and width to control the placement of the
sections. A user coordinate system (UCS) will be created for each cross
section with the same name as the cross section. You can set this UCS
current and use the section tools command to draw and label objects in
the section. Make sure that you have the correct scale set in the
section tool dialog box. |
|
Section tools. |
|
You may draw by entering the slope (3:1), ft./ft. (0.2), %grade (0.5),
or Station and Elevation. Place and label a manhole by station and
elevation orconstruct an offset using the vertical scale. Select a line
or polyline and Section tools will label the slope (3:1), ft./ft.
(0.0156'/ft), or %grade (0.05%). Pick a point and label a Station and
Elevation, or just an Elevation. Place a manhole and Section tools will
label the station, rim elevation, and up to three invert elevations. |

Sewer profiles. |
|
With Sewer Profiles you can place inlets, inlet manholes and manholes on
your plan drawing by station and offset, using user definable blocks.
Sewer Profiles then places a data block allowing you to enter important
information about the structure (such as rim and invert elevations).
Data blocks may be placed on any structure whether existing or proposed.
Sewer Profiles are drawn automatically on your profile drawing. Just
select the structures that you want to use to create a profile and Sewer
Profiles does the rest. A sewer profile with structures annotated,
inverts labeled, and pipe lengths and grades calculated and labeled
automatically. Plan notes may also be created from selected structures.
A note containing the structure call out, station & offset, rim
elevation (or E.P. elevation for inlets), and invert of structure is
written automatically and placed where you choose. |

|
Displays the cut and fill volumes based on average end areas. |
