Hi All, I have a general question and would like some feedback from others who may have encountered the same problem. I have a Creo cast and machine model, for which I am about half way through the drawings. I have now realised the datums needed on the drawing are not related to how the part sketch dimensions were created. My question is how would you handle this? Do I now go back to start of model tree and redo all features so the dimensions all reference back to the datums so the drawing can be parametric or just use driven annotations in the drawings.
