Hi Pascal - I am using Microstation Connect Update 9 with Descartes version 10.07.00.23

The message "No valid element found in model" occurs when selecting the 3sm model which has been created by the ground extraction tool.

Hi Danny,

What product and version are you using? Also, can you elaborate at what step the "No valid element found in model" message appears?

Hi Danny,

You are right, seem the 3SM terrain created has not the terrain property. I'll check with certification.

If you are using a Bentley Civil product (e.g. : PowerInroads) a workaround would be to create a classify point cloud and import this point cloud.

Note that you might have to recreate another POD file with just the detected ground points.

To do so just attach the POD file created and use the Export function with the following parameters :

HTH,

Hi Mathieu, I tried what you said but still no success - now says "No valid element found in model".

How is the best method for creating a terrain model from context capture? To capture the breaklines I am drawing them in Descartes to create the STM. Quite a long process! Ground extraction will work but the mesh is too dense to work with.

Hi Danny,

If your 3SM has been generated by ContextCapture it cannot be tile because ContextCapture generates 3D 3SM (containing terrain + objects).

What you can do is to first extract the terrain with Descartes' ground extraction tool then you will be able to use the Tile Terrain function on the newly generated 3SM.

Thanks,

Mathieu
