External NPT threads: doable?
External NPT threads: doable?
(OP)
I was perusing some old threads about creating an external thread with cosmetic threads. I'm not finding an option though to create an external NPT thread. Is it possible to do it "legitimately", or do I have to wing it?
(my part is a little chunk of pipe 3" long, with 1-1/4" NPT thread on the outside)

There is currently no way to create external threads using the hole wizard. You might want to question your thoughts if really important to show. As a possible way model a pipe and then add a cut extrude or revolve cute if you wish to show taper to simulate the external NPT threads. Next rename feature in design tree to 1.25" EXT NPT so you remember. You can then add a NPT callout on drawing.
You can also probably create add cosmetic thread if you want.

RE: External NPT threads: doable?
I went to your thread...for some reason it's not owrking for me.
My OD is about 1-5/8. It won't let me specify a diameter any larger than .4125" ("Please enter noumber between.00000 ans .4125")
This is an external NPT thread. Should I be selecting the circular edge of my part? ie: the small end of the cone?
I'm trying all different ways. I tried jsut a simple straight externals thread on a dummy part and it worked. just fine. I can't seem to get my NPT thread though....

It's not perfect. Sometimes it will not get the thds I want either. Sometimes you have to fake it.
