Non-DWF Files Non-DWF files that can be used in QTO include PDF files, DWG files, and image files, such as JPG, TIF, and GIF. Because of variations in publishing methods, the source application of the DWF file determines the level of automatic takeoff functionality that will be available when you import the file into QTO. You can use DWF files (and DWFx files) that are published from several design applications. Using DWF, you can combine rich 2D and 3D design data, as well as other project-related files, into a single, highly compressed file. DWF Files DWF stands for Design Web Format™, which is an open, secure file format developed by Autodesk. All data associated with a given estimate is stored in a QTO project. Both DWF and non-DWF files can be used as source files. Overview Using QTO, you can combine multiple sources of two-dimensional (2D) and three-dimensional (3D) design data and generate quantity takeoff to create a cost estimate. You can follow this workflow when you create your own takeoff projects. Use the exercises in this guide to learn how to use QTO by following a typical workflow.

QTO gives you the tools to perform digital quantity takeoff, which is faster, easier, and more accurate than manual methods. Autodesk Quantity Takeoff Getting Started Guide Welcome to Autodesk Quantity Takeoff 2012 (QTO).
