So I imported a valve into SolidWorks from an .igs file. I made necesary changes and then made a drawing out of it. The problem is, my boss wants me to change some of the dimensions in the drawing and I don't know how to. Normally I would go to the sketch level of the part and change it, but there is no in this instance. Is there anyway to change dimensions in a drawing to make them driving and change the geometry of the model, any help would be greatly appreciated, thank you.
