A typical workflow begins with a design file created in Autodesk design applications, such as AutoCAD, AutoCAD Architecture, AutoCAD Civil 3D, and Revit. Before publishing a design file, an architect, engineer, or other designer, determines which features (model, layouts, layers, properties and so on) to include in the file. After determining the content, a designer publishes the drawing and shares the file with the Estimator. In some cases, designers scan or save drawings as image files and send them for estimation. When the files are received, the Quantification workflow begins.
