How can I do manufacturing drawings when the way the model is built does not represent its manufac.?
I have seen this video https://www.youtube.com/watch?v=Hky98wUL-jo&list=PLRhPac0z_f-FIsmKbE1fR1ZlEMXBZcZvN from David Martin on worst drawing practices. There, he says that most dimensions should come from the model. In this video https://www.youtube.com/watch?v=cxKmlE8afhs on worst modeling strategies, he says that you should not create your model in a way that represents manufacturing. But, when I make a drawing, it is mostly for manufacturing. And if I did not build my model in respect to manufacturing, then I can not take the dimensions etc. over from the model. I also have made the experience that when I make a new model, it is built up in a way that is different to how it is manufactured. For example, the lathe operator maybe needs diameters and everything dimensioned to one edge of the part. But, when I modeled the part in Creo, I maybe dimensioned a revolve in reference to another revolve. So they do not reference the same edge. Does somebody maybe know how to deal with this? Thanks for any ideas and replies! Please write if you need additional information or an example as a model etc.
