Level three Clashes
These clashes are considered important to the correctness of the model; however, they will usually
change on a regular basis throughout the design and construction process.

Using the Interference Check tool
The Interference Check tool is a basic tool supporting 3D coordination. You can use it within a
single project model or between linked models. You can also select elements prior to running
the tool in order to detect clashes within a limited set of geometry instead of the entire project.
For more powerful clash-detection capabilities, Autodesk offers Navisworks Manage
®
(www.autodesk.com/navisworks), which is a multiformat model-reviewing tool with various
modules supporting phasing simulation, visualization, and clash detection. Figure 6.19 shows an
example of a model in Navisworks Manage comprising Revit, Tekla Structures, and AutoCAD
MEP components. Some of the benefits of using Navisworks for interference-checking over
Revit include automated views of each clash, grouping of related clashes, enhanced reporting,
clash-resolution tracking, and markup capabilities. Revit models can be opened directly in
Navisworks or exported directly to the Navisworks format from the Application menu.
