topic Family Table with varying external threads in 3D Part & Assembly Design https://www.ptcusercommunity.com/t5/3D-Part-Assembly-Design/Family-Table-with-varying-external-threads/m-p/232066#M81761 <HTML><HEAD></HEAD><BODY><P>I have a family of parts that I need to create. Each part has an external thread that varies in size up to 3/8-20. My company has an internal document that governs the undercut length (from pitch of thread) and undercut diameter (from minor diameter). Can anyone offer up some advice as to how to setup the family table and the relations? I am thinking that I am going to have to create a custom table that will be referenced. Does that table need to be internal or external to the part? Is an external reference even possible? Any help will be appreciated.</P><P></P><P>Regards,</P><P>Justin</P><P>Creo 2.0</P><P>M090</P><BR /><STRONG>This thread is inactive and closed by the PTC Community Management Team.
