In an automated way we want to allow users of AutoCAD and derived software products to better automate the export of CAD elements (products of the library) (already exported in a bill of materials) including for example measurements (length, type) of electrical cables, pipes, etc. The output format could be in XML and it will be automatically imported in a product which creates offers to end customers. Any changes in the CAD will then be reflected in the output including attributes such as lengths, heights, types, other sizes, and other attributes plus the total quantity of each product in units such as meters, millimeters, quantities, etc. This is a plug-in/extension using already defined data structures. The developer should have very good knowledge of AutoCAD, its API and a technical background also in engineering.
