I'm not a SolidWorks user but a friend of mine is helping me to create an aerator for a faucet and is having problems with creating the threads. I gave him the thread sizes which are 15/16" male threaded and 55/64" female threaded with 27 threads per inch. He says this is not included in SolidWorks. I'm not sure off-hand which version he's using. Is there a way to download this? Or what would be the way to create the threads so that they are accurate once they are molded in brass? Would you not include the threads in the mold and have them tapped later? Thanks for any insight!
