From the Inventor 2015 What’s New page in the Help:
“Default thread depth and hole depth value specified from thread.xls
Standards now control thread depth and hole depth default values. While creating a hole, you often apply a thread feature. The values for thread depth and hole depth reference the associated (new) Thread Depth and Runouts columns within the thread.xls. “
What does this mean?
There are new columns of information in your thread.xls file in Inventor 2015!
If migrating Design Data from a previous version of Inventor and there is a custom “thread.xls” file, a proper migration may require editing this file to include the new columns.
