Clashes detection

Hi,

is it possible to export clashes detection result to BCF file ?

thanks

  • What happened to this?

    There is no point in Clash detection if I can't notify my consultants that mostly don't use OBD.

    If a Saved View was created for each clash - that will come over to a 3d-pdf -can one write a macro for that?

    Are saved views carried over to dwg or ifc?

  • What is BCF?

    Dwg has the concept of Named Views. Can dgn-Saved Views be exported to dwg-Named Views I think it would be a fine route.

    And then a macro/mdl that creates a saved view for each collision instance in the xls.

  • BCF is an open format for issue management. It saves both the viewpoint (camera angle, section planes) as well as visible/hidden items. At the same time it can add information like labels and comments. Assign to a person, ...

    The huge benefit of using an issue manager (or BCF manager) is to keep track of open/closed issues. Set deadlines and assign issues to specific people to answer.

    It is mainly used in BIM (coordination) based on IFC format. There are many viewers, like Solibri or BIMCollab Zoom, that include some sort of Issue Management. Even Navisworks has such a feature in combination with BIM360/ACC (not BCF compatible).

    The main benefit in my opinion of such an open format is that it can work across multiple platforms. The modeller can use the BCF manager from their application (in case of Revit, Tekla, Allplan, Archicad, ...) while the person doing coordination can use a different application (Navisworks, Solibri, BIMCollab Zoom, ...). Stakeholders like designers or clients can use a (free) easy-to-use application (IFC viewer) to also check the model and make their remarks or answer the questions that are asked.

    In my opinion BCF should always be used in combination with IFC exchange. It could work on DWG as well I guess. The most important thing is that all applications/models use the same origin coordinate. Otherwise those camera angles will be useless.

    With OBD two very useful workflows can be thought of using BCF:

    • Either OBD is the modelling application, then IFC is exported for coordination purposes. The person doing the coordination uses a 3rd party application, makes their remarks and assigns them to the OBD user. Then this person can simply navigate through the issues that need to be resolved and make the changes in OBD. Then export IFC again an the next iteration starts;
    • Or OBD is used for coordination purposes (like the original topic starter). It loads IFC, DWG or other compatible models that are created either with Bentley or 3rd party applications. Clash detection is performed, issues are created and assigned to those 3rd party people. They can open the BCF issues in their own application and easily see what needs to be adapted.
  • If there are more than one really good free viewers i would support that route.

    My solution is more of a quick and dirty hack. But perhaps is faster to implement?
