The NHProfile program is used to draw MX profiles that can be transferred to MicroStation. When followed with the MicroStation routines described in Transferring MX profiles to MicroStation profiles conforming to NHDOT standards can be developed.

Before You Begin

The minimum required data includes:

  • Reference model.
  • Proposed master alignment reference string. By default, this string is also used for displaying proposed elevations.
  • Geometry string - All annotation comes from the GEOMETRY String that is associated with the specified proposed master alignment reference string.
  • Old Ground String profile string. This string has an OCxx string label that corresponds to the master alignment reference string (MCxx).

In MX from the Add-Ins menu, select Personal Add-Ins > NHProfile-v8i. If necessary, add the program to your MX add-in list. If you need help doing this, refer to the MX Add-In Index.

Running the Program

  • When you begin the program, the panel shown below is displayed. If this Add-In has been run before, it may populate many of the fields with previously used data. If the previously used data no longer exists in the model file, the program will fail. If this is a problem, then delete the NHPROFILE.INI from the MXDATA folder under the project's PRJ folder. The next session will have all fields blank, just like the first time.

  • Select the Reference Model and Reference String. This is the master alignment string that will define the stationing for the profile drawing. The Proposed Profile field will update to contain the same string as the Reference String field. If there is not a corresponding Geometry String, then you will get a warning message that it does not exist. Select Yes if you wish to continue drawing this profile.
  • The Existing Ground Profile dropdown should include any strings in the reference model beginning with "OC". If not, then select the "OC" string from the MX Display. This string is checked for null elevations.
  • By default, text on the profile will be sized for a 50-scale drawing. Toggle the Text Scale to "20" if the MicroStation drawing will be 20-scale.
  • By default, the NHDOT Design standard Scale Ratio for profiles is 5:1 between horizontal and vertical. This can be modified to use a 1:1 ratio or select Other to manually set the horizontal and vertical Scale Ratio.
  • A drawing name can be specified from the DPW Name dialog box. If this field is left blank the program will use "pro_" followed by the reference string label. In this example, the drawing will be called pro_MCOM.dpw.
  • A Title can be added to the profile. The first line is typically the project name & number. The second line is typically the route number or road name.
  • Start and End stations can be adjusted if the entire profile is not needed.
  • The Vertical Datum is the lowest point of the profile grid. It defaults to a point below the lowest point on the profile. This value can be modified if desired.
  • Select the appropriate Vertical Datum reference. Obtain this information from Survey.
  • The default Decimal Format will be shown to 2 decimal places on Imperial profiles and 3 for Metric. These values can be adjusted if necessary.
  • The Format area can be used to select a profile better suited for Preliminary design (with a full grid) or Final design construction plans (limited amount of grid lines).
  • The Black & White Drawing option is only to be used if the drawing is to be plotted from MX. This will force all colors to black or gray to create better black and white plots.

Click the Draw button to draw the profile. An input file will be generated so the drawing can be recreated later without running this Add-In program again. In this example, the input file will be called pro_mc1b.drw. This file should be stored in the project's MX directory although it does occasionally get placed somewhere else. The file may end up on the users C:\ drive and should be moved back to the project's MX directory.

Review Transferring MX profiles to MicroStation if the profile is to be brought into MicroStation.

Known Issues

  • MX must be running before starting the program.
  • When selecting the model name and reference string, select them from the pull-down list. Attempting to key-in the first character doesn't always work properly.
  • If a long alignment is selected, it will take a few moments to process the data after the Draw button is pressed. Please be patient.
