A previous tip detailed that using any of the Flood Methods in MicroStation requires the entire region being flooded by visible in the view window.

MicroStation Tip: Flood Methods

A Commenter asked how to do this for a long, thin region where you couldn’t identify a point inside the area.

Here is how to accomplish that task…
In the image below we have a long roadway segment. There is a 25′ wide strip along the right side of the center line we want to fill.



  1. Zoom in on the shaded area (or any area along the region) so that we can identify a blank area inside the region to be flooded.
  2. Select the flooding tool (in this case Create Region) and configure the desired tool settings
  3. Place a tentative point somewhere inside the area to be flooded for the flood point – The tentative crosshair will have a dashed symbology
  4. Use your mouse scroll wheel to zoom out so the entire region is visible
  5. Click a data point (<D>) to select the tentative point
  6. The bounding region will highlight
  7. <D> again to complete the flood
  8. The region is now filled.
