meeboboy Posted November 10, 2012 Share Posted November 10, 2012 Hello, I am new here so hopefully someone can help me. I need to know how to draw an NPTF pipe thread, male and female. In 2D. Any good reference book would be welcome. An NPT thread differs slightly from that of an NPTF, but thats ok. I have AUTOCAD 2002. I am trying to update some of our drawings at work. Any help would truly be appreciated. Thank you. Quote Link to comment Share on other sites More sharing options...
