How to conduct clash tests in Revit?

Clash-Detection

Interference checking is one of the most important features of Revit that assist multi discipline design team members to find out the clashes in between model elements of various models. Clash tests are run by Revit users so that the potential threat from clashes can be resolved well in advance by dispensing feasible solutions for the problems. When clashes between the model elements are eliminated or resolved in the pre construction stage, seamless construction takes place on the proposed location.

The Process of Conducting Clash Tests in Revit

In Revit, clash tests can be conducted to find out coordination problems or interferences within the host model as well as between the host model and linked model. Below is an example of how to conduct clash test between structural and MEP Modeling Services.

  • The first and most important step in this is to deliver an updated model to the designers of other disciplines. For example clash test is conducted between MEP Model and Structural Model; in this case, MEP engineers or modelers will first receive an updated structural model.
  • The MEP engineer will then have to go first to collaborate tab in Revit and from there to ‘coordinate panel’. After clicking on ‘coordinate panel’ he can click on to ‘interference check’ option and from there he has to select ‘run interference check.’
  • From the ‘interference check,’ dialog box Revit users can select objects from the host file which can be checked for conflicts with the objects from the linked file.
  • After objects from both the host model and linked models are compared, the ‘Interference Report’ dialog then displays a variety of conflict instances. Revit users can optimize ‘show’ button to find out or view the colliding elements.
  • So after finding the clashes, the MEP engineer can start working from his end by making necessary changes in his model elements.
  • If in case the MEP engineer wants to relocate the changes in his model elements he has to rerun the interference check. This can be done by again going to ‘collaborate tab’ and then selecting ‘coordinate panel’ from there he has to select ‘interference check’ and finally he has to click on to ‘Run Last Report.’
  • By doing so, Clash Detection Services are displayed. The test can be run again by selecting the ‘Refresh’ button. If for instance clashes among the MEP model are solved, the ‘Interference Report’ will show nothing in it after refresh.
  • So when the updated MEP model is received by the structural engineer he will find no clashes in it if he runs a clash test.

This is how clashes are detected and solved in Revit.
