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, the architect, engineer, or other designer, determines which features (model, layouts, layers, properties and so on) to include in the file. After determining the content, the designer publishes the drawing and sends file to you. In some cases, designers scan or save drawings as image files and send them to you for estimation. When you receive these files, the Quantification workflow begins.
