I have a part with a few dimensions that I want to vary in predetermined steps and then create new parts based on those varied dimensions. Basically, I have a nozzle whose diameter I would like to vary incrementally, and I want to create a new part for each "new" nozzle. Honestly I'm not sure if this is even the best route, but the end goal is to create multiple 3D printed prototypes to physically test the variations. (I also at some point in this process need to convert the files to .STP for the printer)

I've been just copying my base file, changing the intended dimension, changing some sketch text on the part to indicate what changed, and then saving it with a new file name. I only need maybe a dozen or so variations so it's not impossible to do by hand. But occasionally something will need to change in the base file, which I then have no way to replicate in the other files and basically have to delete everything and start over. If the process was automated this wouldn't be an issue, or maybe if everything was a different configuration they would update automatically?

I haven't experimented with configuration specific sketches/features, because this doesn't remove the leg work from manually changing dimensions. I also don't see a way to automatically update the sketch text, which is basically necessary given the similarity of the parts. I thought about using a design table and just setting up the variations in excel, but again I don't see a way to actually create a new part based on the increments using that.

Any help is appreciated. Thanks.
