The way clashes are highlighted in Mstn V8i and ABD is pretty rudimentary.
The two elements are highlighted in red/blue, without any visual indication of where exactly the clash is. This forces the user to guess where it is, which is sub-optimal and only OK for simple clashes. More importantly, when looking a large number of clashes, it is important to understand what clashes ideally need to be dealt with first.
To de-clash a model effectively, you need to identify the 'key logs' in the log jam of clashes. You need to be able to clearly identify and prioritise them. Without more localised or precise highlighting, the user only gets a mass of red and blue elements that only signifies another depressing hiding to nothing.
It would be good if the platform team could include something like what the Subsurface Utilities (SUE) vertical team have provided. They have managed to place 'spheres' where the clash are. I think that the 'blue spheres' can be replaced by other objects using rules and the Element Properties panel. There is even an option to merge the clashes based on proximity.
Similar implementation available for Revit and Tekla BIMsight
Maybe the new Display Rule engine could be used to colourise the clashes according to severity or type etc etc.
Again, Bentley has been ahead of the pack and benefited from the detailed use case feedback from its diverse family of verticals based on its universal platform (compare this to Adesk's Revit v. ACAD v. Infraworks etc or Trimble's Sketchup v. Tekla v. Solibri etc mess). The current imprecise clash detection highlighting is obviously no good if the pipe or roadway is miles long. Hopefully, this capability can be shared across all verticals without too much tinkering.
