Measuring distances to nearest surface/mesh/element (or Point Cloud) along an alignment corridor - Gauging with Point Cloud Data

I am trying to undertaking gauging exercise along an alignment against point cloud data.  I have the alignment in CAD Bentley Rail Track format.

I also have the point cloud data in surface/mesh form if needed.

I need to record distances to nearest points taken from surface/mesh/point cloud.  These distances will be measured from the alignment left hand running edge. It needs to be an automatic process along the alignment corridor at regular set intervals.   Ideally the results need to be reported out to a text file. 

Is this possible with the swept envelope tool?   Or creating a corridor assembly and using it to auto defining points that intersect with a surface? 

Or is there another tool in Bentley Products that can do this?

Thanks

  • The quickest way to perform such analysis is to do clash detection between meshes or solids and the point clouds.

    This can be easily done using Tools/Clash detection

    You just have to put clouds and meshes/solids in different levels.

    Unfortunately you don't have any detail (list of points and value) using Rail Track. I must check with Bentley Descartes as it may provides more details.

    So next question is: how to get the envelop ?

    You can do a swept envelop analysis or create a corridor. The later is easier because you will get a single mesh.

    You can also extrude a shape along the 3D alignment using basic MicroStation 3D modelling.

    Anyway it does not provide exactly what you do expect.
