revit structure 2008 - interference checking     Interference Check is a very easy way to check and see if your model has clashing objects. You can pre-select specific objects and run the check on those objects or you can wait and decide what to run the check on once inside the dialog box. At any point before running the check you have the opportunity to ‘filter’ the object ‘Categories’. As an example you can check for interference between only Structural Framing objects and Walls. It’s very straight forward and you can even include a ‘Linked’ model as you will see in lesson 3.     CADclips Login required to access these lessons.
