Preparing MX Plan Drawings for MicroStation

Check the project's MX directory for a file with the project name followed by a .mss extension. If this file does not exist, see a member of the CAD/D support staff before continuing this procedure. If it does exist, open the file with PFE or Notepad to verify it is correct. It should include the following settings:

Imperial Version
[SEED_FILES]
MX_MODEL_SEED=nhseedf2.dgn
MX_DRAWING_SEED=nhseedf2.dgn
MX_CELLSEED=exist-in.cel

Metric Version
[SEED_FILES]
MX_MODEL_SEED=nhseedm2.dgn
MX_DRAWING_SEED=nhseedm2.dgn
MX_CELLSEED=exist-in.cel

Any references to mx_seed_m.dgn or mx_seed_ft.dgn will need to be corrected.

Setting the Model Defaults

Before creating the MX display, check to make sure the model defaults are set to the type of drawing desired. Consider for example that a design model requires the MXROAD style and feature sets for MX design operations. However to create PLY drawing, the Model Default must be changed to the PLY8 style and feature set.

This graphic shows the proper Model Default for an existing ground model. The appropriate style and feature sets for the most common plan drawing types are as follows:

Proper Model Default
Drawing Type Style & Feature Set
Existing Detail EXD
Contours CTR8
Proposed Detail PLY8
"Others" Style Sets

On the Edit Model Style and Feature Set panel, insure that the box labeled Lock Style and Feature Set is checked. Select the ellipsis button button next to the Style Set Name to choose a different Style Set. The feature set should automatically update. Click OK to save this information.

Creating the MX Display

display: plan with set style dialog box

Create a blank display by selecting New Plan Display... from the File menu. Enter the new Drawing File Name and click OK. Refer to Drawing Naming Conventions for standard drawing file names.

To draw the detail select Plan with Style Set... from the Display menu.

Select the model name to display from the Model Name pull-down menu.

To check and/or reset the Model Defaults, right-click on the model name and select Edit Model Defaults. Remember to only draw a model with the Model's Default style set. No longer use the Style Set Browser button on this panel.

Uncheck the Draw all Strings box so only items in the feature set are drawn.

Select OK to Display.

Export from MX

While still in MX, from the File menu select Export > Native. A new MicroStation drawing is generated with the same name as the current drawing but appended with the word Native. When working with a design model, consider returning the Model Default back to MXROAD.

MicroStation Drawings from MX

Enter MicroStation, select the appropriate project and new MicroStation drawing just Exported (Native) from MX.

Levels need to either be attached or imported from the appropriate level library. From the Level Manager dialog box, select Levels > Attach... to obtain the Attach Level Library panel OR select Import... to obtain the Import Levels panel. Choose the level library (*.csv) that matches the new drawing.

Next, click on the Update Levels button (the 3rd button), this will set the correct default values for each level in the drawing.
