PROFILE GRADE REPORT

This application provides the ability to store Profiles and/or Chains into the GPK file based on element positions in your proposed cross sections. The Profiles and Chains can then be drawn with D&C Manager later.

ASCII text reports can also be generated.

There are 3 different ways to store these Profiles and/or Chains:

A couple examples where this tool could be useful:

1. Laying out elevation views for retaining walls, that illustrate the various profiles involved, (Edge of Pavement, Top of Wall, Bottom of Wall).
2. Determining potential ditch blockages (see Special Ditch Grades) and culvert placement.

Invoke the XS Report dialog by using the MicroStation pull downs:

APPLICATIONS > GEOPAK ROAD > CROSS SECTIONS > REPORTS... or from the Road Tools icon as shown below:

The XS Report dialog will appear as shown below.   Click User and fill out the Report Header Dialog box.  This Report Header information can be saved by clicking on File and selecting the path and file name to be saved.  When finished, press Profile Grade on the XS Report dialog.

The Profile Grade Report dialog appears as shown below. The look of the dialog changes dynamically depending on which of the 3 options are selected from the combo box:

• Key in the Job number, select the Chain and key in the Profile name.

• If you want to consider the entire chain, highlight the Beg Sta. field and press delete.   The application will automatically set this field to the beginning station of the chain.   Repeat this for the End Sta. Field.   You may also simply key in a desired station range.

• Enter all the appropriate Existing Ground Line element symbology, by clicking the button to the left of the Display button and identifying the elements graphically, using the Match button as shown below:

  

• Enter all the appropriate Proposed Finish Grade element symbology, by clicking the button to the left of the Display button and identifying the elements graphically, using the Match button as shown below.

  

THE OPTIONS:

Criteria Elements:

When the option is set to Criteria Elements, the application will be looking along the Proposed Finish Grade element path and storing a point number at the lowest elevation on either or both sides of centerline in the cross section file.

To store a chain that reflects the horizontal position of the lowest elevations, toggle Store Horizontal Alignment on and type in a Beginning Point Number. To store a chain representing the left side of centerline, toggle LT Chain on and type in a name. To store a chain representing the right side of centerline, toggle RT Chain on and type in a name. An initial stationing of 0+000 (0+00) will be utilized.

Note: The chain name should conform to standard GEOPAK convention, i.e. 1-9 alpha numeric characters with no special characters.

To store a profile that reflects the lowest elevations, toggle Store Vertical Alignment on. To store a profile representing the left side of centerline, toggle LT Profile on and type in a name. To store a chain representing the right side of centerline, toggle RT Profile on and type in a name.

There are 2 options available for stationing the profiles:

1. Station Design Alignment: The stationing of the Chain selected at the top of the dialog will be used for the profile stationing. Storing a horizontal alignment is not necessary for this option.
   
   
2. Station Low Point Alignment: The stationing of the Chain created from the Store Horizontal Alignment option will be used. The Store Horizontal Alignment and appropriate LT Chain RT Chain toggles must be on, and the chain name must be typed into the dialog.
   

Note: The profile names should conform to standard GEOPAK convention, i.e. 1-9 alpha numeric characters with no special characters.

Search Text:

When the option is set to Search Text, the application will be looking along the Proposed Finish Grade element path and storing a VPI at each instance where the search text characters are found on both sides of centerline in the cross section file.

The example above illustrates searching for the text "BDT". NOTE: The standard (.x20) criteria for WFL automatically places the text characters BDT at the bottom of the ditch on both sides of centerline.

Notice how the Search Text option doesn't specifically allow the ability to store separate profiles for left and right. In the case where the search text is found on each side of centerline, the program automatically sorts left text from right text and stores them separately. As you can see from the illustration below, 2 profiles were stored into COGO, Ditch and Ditch-1. The profile name with the appended "-1" represents the profile on the left side of centerline.

When the "Stationing" option is set to Sta Design Alignment, the stationing of the selected chain (at the top of the dialog) will be used. It is also shown to the right of the Store Prof name field.

When the "Stationing" option is set to Sta Text Alignment (shown below), the user has an option to also store a Chain representing the horizontal position of the search text found on each cross section. When the Store Chain toggle is unchecked, the stationing of the profile will be the design alignment. When the Store Chain toggle is checked, the stationing of the profile and the chain will begin with 0+000 (0+00).

This dialog is very typical and found throughout Geopak. Whenever any changes are made to entry fields or toggles, the Add, Modify or Delete buttons must be pressed in order for the changes to take effect. Examples are shown below:

        

Offset:

When the option is set to Offset, the application will be looking along the Proposed Finish Grade element path and storing a VPI at the intersection of the proposed finish grade elements and the offset specified.
