I had the honour of presenting at this month’s BIMbc user group meeting on the topic of model-based coordination. While this can be done in Revit, even using the freely available Revit viewer, there is always the issue of having manageable and responsive models that are easy to navigate and share. Tools like Navisworks and BIMsight fill this need by providing a quick way of navigating a model for the purposes of extracting information, associating files with objects and clash detection among others. Below are the slides I had prepared for the presentation giving my perspective on the two products. The slides focus on the degree of development of the measurement dimension tool in both programs.
