The following standard data tables are provided to set the default parameters for Drill Size Hole, Screw Clearance Hole, Threaded Hole, and Hole Series features:

External standard data table files (that is, lookup tables) provide the best fit default values for holes features. You can choose to bypass the tables and enter all parameters manually.

These tables provide default values for the threads, start chamfer, end chamfer, neck chamfer, and relief chamfer parameters, based on the best fit standard for the selected type of Hole feature.

You can customize these data tables as required. For more information, see Customize standard data tables for Hole features.

Note:

When you customize the standard .xml files, you must retain the column names that define the hole parameters.
