Bentley MicroStation Plugin


MicroStation Plugin

Export to LumenRT: The Bentley MicroStation LumenRT Export Plugin works with all Bentley MicroStation based products including AECOsim.

With a 3D camera-enabled view displayed, go to the LumenRT task menu and click the Export to LumenRT button. This will initiate an immediate export of everything visible in the scene including model elements, LumenRT proxy content and lights.

[Note: You must have a camera enabled for the active view in order for LumenRT to successfully export the model]

 


To Export a DGN Model to LumenRT

Select the LumenRT tool (Visualization > Home> LumenRT

Adding LumenRT Immersive Nature Content

LumenRT content is stored as a cell library in MicroStation. Navigate to your MicroStation LumenRT content folder and load the LumenRT Content cell library named CellsForLumenRT. This is found in the path ProgramData\Bentley\connectsharedcontent\CellsForLumenRT

 

Access the cell library

You can access the cell library by going to Element>Cells to display the list of available Immersive Nature content items. LumenRT content items can be added as regular cells or shared cells.

Exporting Lights

In MicroStation, lights are added to the scene using the standard MicroStation light command under the Visualization tab. Both point lights and spot lights are supported. Also the Light Manager setting helps to adjust all the parameter related to Lights. And when the model finally exported into LumenRT these same parameter is shown to the interface.

Exporting MicroStation Traffic Animation

MicroStation Traffic Animations are automatically exported each time a model is exported to LumenRT. You must be using any version of MicroStation CONNECT to export traffic animation. MicroStation allows to create traffic within the application but MicroStation Traffic animations must use LumenRT vehicle proxies in order for the exported path to be visible in LumenRT. LumenRT vehicle proxies are found in the LumenRT cell library (CellsForLumenRT) located in your ProgramData\Bentley\connectsharedcontent\CellsForLumenRT.

[Note: MicroStation Traffic Animation models must not have Geo-Location inside of MicroStaiton. You can turn Geo-Location off by going to Tools>Geographic and deleting the GeoCoordinate system. Your animation and model sizes will still be maintained even after deleting the GeoCoordinate system.]

Exporting VISSIM Traffic Animations

To export VISSIM animation from MicroStation, click the LumenRT export with VISSIM button or click the Use VISSIM check box in the LumenRT settings menu (CONNECT). The export dialog shown below will appear. Enter the path to the VISSIM animation.ani.txt file and any path offset.

To Export a DGN Model with VISSIM Traffic to LumenRT

  1. Open the LumenRT Settings dialog ( Visualization > Home > LumenRT > LumenRT Settings ).

  2. Turn on the Use VISSIM check box.
  3. (Optional) Set Vissim offset.
  4. Click OK.
  5. Select the LumenRT tool (Visualization > Home > LumenRT > LumenRT).

  6. In the Select Vissim File dialog that opens, select the VISSIM traffic animation text file (.txt) and click Open.

  7. LumenRT exports the model along with the VISSIM traffic animation to a .lob file and opens the file in LumenRT.

  Used to control settings to export a model to LumenRT.

You can access this dialog from the following:
 
Setting Description
Stroke Tolerance (Meters) Controls the number of triangles that curved surfaces are broken into before being rendered. Smaller values produce smoother results but at the expense of render times.
Use VISSIM If on, exports the Vissim traffic simulation information to the LumenRT file.
Vissim X Offset (Meters) Allows you to set the Vissim X path offset.
Vissim Y Offset (Meters) Allows you to set the Vissim Y path offset.
Vissim Z Offset (Meters) Allows you to set the Vissim Z path offset.

 

Exporting MicroStation Camera Paths

If an animated camera path is present in the MicroStation model, this will automatically be exported into LumenRT and appear on the LumenRT video clip timeline.
