Model based quantification isn't new, but combining it with the ability to combine Building Information Models from multiple file formats, take quantities directly from the Building Information Model, then run change analysis as the model changes we think is an important part of streamlining this generally time consuming and laborious process. In a short series of posts we'll explain what Quantification in Navisworks is and how to set it up, how to take off from your Building Information Model, and how to analyze changes when new iterations of the model come in.

The process of measuring quantities of materials from models, drawings and specifications prepared by architects, engineers, and other designers is known as takeoff. Quantification is a core piece of functionality of Navisworks. Using a 3D model, you can create a highly accurate quantity takeoff that ties it physically to the model. This allows you to see items that have been accounted for—and those that have not—and make more accurate material estimates.
This Course shows how to set up a takeoff workbook using the built-in catalogs in Navisworks, use your own custom catalogs, and perform model and virtual takeoffs. Plus, learn to perform 2D takeoffs from a DWF sheet set. You can estimate construction and renovation projects, so you spend less time counting and measuring and more time analyzing projects.
