If you want to takeoff objects that have geometry in the model, but no associated properties, you can use a virtual takeoff. This may be the case if you did not save the object properties from the original design application, such as AutoCAD or Revit. In this instance you can use measurement tools and formulas to add some property details to the Quantification workbook. You can also associate a viewpoint with the takeoff object, to help reference its position in the model.
