Engineering drawing An engineering drawing is a DOCUMENT derived from a part. projects views from the part's geometry, places dimensions between points ON that geometry, finds centre marks on it, and lays the result out on an ISO sheet with a frame and a title block. Change the model, rerun the drawing script, and the views, hidden lines and measured values move with it. Nothing on the sheet is drawn by hand, and nothing on it is a number you typed unless you chose to override a value. The output is one PDF. That is what a shop receives and what every operating system opens. No DXF is written…
