clash checking against a POD file? Which software enables this?

Hi,

Network Rail have POD files for the whole of West Coast mainline and I have been asked to look at possibilities of checking OLE clashes with Civil models and PODs.

I thought there would be a Clashchecker available, is it Bentley Descartes or the PointCloud software?

  Any advice , hints & Tips?I don't think the nomal range of Clash Checker software used in PetroChem wouldn't be able to clash point clouds against graphic models.

Am I wrong?

  • Hi Karsten,

    The clash detection module offered in MicroStation has been supporting point cloud since the end of last year.

    Thanks,

  • That's correct but I believe that you require an additional license as discussed in this thread

  • There will be two main differentiators between Pointools and Descartes for that workflow.

    •         Pro Descartes: To use Pointools, the user will have to import his vectors into Pointools environment

    •         Pro Pointools: In Pointools you can calculate the clashing of a moving part along a path

    Bentley Pointools V8i includes a new and unique toolset to test for clashes and differences. A clash detection test will effectively identify and report any interferences between any two (or more) objects. These clashes or interferences are useful to check if an object can fit within the bounds of the environment it is in, or is proposed to be in. A difference test will examine two objects and highlight any differences found, either additions or subtractions.

    Both clash and differencing tests have the ability to test point clouds against point clouds, and point clouds against 3D model objects.

    Descartes now supports Clash Detection for point clouds.  Clashes can be detected between point cloud and point cloud or point cloud and vector geometry.

  • If Microstation Clshchecker supports PODs do you gain anything using Decartes or Pointools?

    USed to run Clashes using PD Clash and Jacobus Clashchecker..

    Both  had Clash managers with clashes being approved or marked as false etc

    They could keep track of clashes on different runs  so once a clash was approved it didn't come up again on a new clash.

    The could do this as each graphic item had userdata Identifiers.   Microstation by default doesn't  tag graphics.

    PDS used to create a MARKER dgn with all clashes saved as cells with unique Clash ID occurnce.

    Does the Bentley ClashChecker do anything like this.  Seems to me it saves the co-ords in the report.. does it save the sect, byte or elem id anywhere?

  • Hi Karsten, Descartes' Clash Module can show clashes that have been resolved.  It can also hold multiple tests in one DGN so this should be sufficient to see progress.

    With Pointools it will tag each clash which can be saved as a 'note' within the PTL (project) file.  

    It's probably best to get a test area and try it with both Descartes and Pointools so you can see the difference and decide which is most appropriate for the task.


    This is a test
