Hi all,


I'm looking into an enhancement request (895128) that we've gotten for adding a lead-in/out option to our Thread command.  I've not been able to track down a specific standard or set of rules that dictate how the tapering of the thread should be created.  So I could use your help with the following:

  1. Is there a specific standard for lead-in/out for machined threads?  For bottle threads? For other threads?
  2. If there is a standard, do you modify it to meet your specific needs?
  3. If there is not a standard for your application, how do you create your lead-in/out?
  4. Would you be willing to share some of your models with me to help me understand what is being done?  Feel free to post them here or send them to me via forum message.


Thanks for your time and help.
