Hi,
I can reference in point cloud data using the Point cloud tool in Microstation v8i, but I would like to import the xyz data directly into a DGN file.
I have converted the *POD into a xyz Ascii text file and tried to import it using the XYZ text import tool but I get an error message.
Basically I would like the data in a DGN, so that I can create a surface using Bentley Rail.
The version of Microstation I am using is 08.11.09.932
Thanks
Matt
Hi Matt, You did not specify what error message you get during import or what settings you have used for this. Please review this wiki article communities.bentley.com/.../26009.how-to-import-coordinates-xyz-and-their-respective-labels-or-text Check if for the import, you have selected Point elements and order xyz as explained there and also make sure that your file has x, y and z values. I recall some issues when importing big files. Try to divide the file in two or three smaller files to import and let us know if you still have issues.
also review this other wiki http://communities.bentley.com/products/microstation/w/microstation__wiki/25677.error-when-importing-xyz-coordinates-from-txt-file
Otherwise post your thread in the Rail track forum http://communities.bentley.com/products/rail_design/f/5921/p/84800/239127#239127 Regards Maria

I don't know Bentley Rail product in detail, but I assume that it's able to create surface (DTM) directly from XYZ and there is no reason to import it into DGN.

There are some other clever tools in BRT/PRT that allows for the creation of surfaces. These tools to not require the information in DGN graphics, so you dont need to bring your POD file in as Microstation points in the method you specify.
If your goal is to create a BRT DTM with your POD file - we can do this with Data Aquisition in BRT. Have a look for it under your tasks menu. See also the attached image.
Attach your POD file, then in Data Aquisition - Click on - Surfaces - Right Click - Create Surface -Import from Point Cloud.
Then set your filter and click Accept on the top left of this window.
This takes the POD file and applies a filter to the number of points to reduce density and other information if required. See attached image for the BRT default on my machine. I think you can use that for now, but play about with it if you want to reduce the surface density further.
Your surface now created in Data Aquisition. In the Data Aqusition window, expand the "Surfaces" tree and find the surface you have created. The deault for mine is "Point Cloud Surface_1". Rick Click - Export To - InRoads DTM and save somewhere.
You can now load this into BRT as a DTM in your surfaces tab.
Hope this helps
