IFC entity selection groups and filters help you to set up powerful clash detection rulesets available whenever you want
usBIM.clash allows you to choose BIM models and the elements to be analysed with maximum flexibility.
You can select objects directly on the model (visually and graphically) or use advanced features such as "Selection Groups" and "Selection Filters" which allow you to specify the files and entities on which to perform conflict analysis.
Advanced features such as "Selection Groups" and "Selection Filters" allow you to specify the entities upon which to perform a geometry conflict analysis.
The chosen analysis criteria can be stored as a template and therefore used as a meta-process analysis that can be repeated each time on the updated models.
The Clash detection results are dynamically updated not only at every model change, or models that have already been analyzed, but also in case new BIM models are added.
