UKIDIOT,
Here are the critical steps and (2) examples......
1)Locate the .hol files that are stored in Pro/E.
2)Make copies of the files that you want to change. It is best to make copies and leave the originals intact.
3)Place the new files in a folder of your choice.
4)Change your config.pro file to look for these files.
(hole_parameter_file_path)
5)Modify the .hol file line "CALLOUT_FORMAT". (see below)
6)Modify "THREAD_SERIES" to a custom name of your choice. This new name will appear in the hole creation dialogue box.
I have included below, the header from one of our .hol files. As I have said, the syntax is critical. The spaces between characters must be exactly right.
TABLE_DATA
PRO_VERSION 22
THREAD_SERIES ISO2
CLASS H
TABLE_UNITS metric
DEPTH_RATIO 1.25
CALLOUT_FORMAT &Metric_Size TAP <CTRL-a>x<CTRL-b> &Thread_Depth
On a drawing, this will read.....
MX x X.X TAP (depth symbol) X.XX
Here is an exerpt from PTC...
EXAMPLE: The syntax for the default UNC callout format would appear in
this way (all on a single line) in the .hol file
CALLOUT_FORMAT &Screw_Size &Thread_Series - &Thread_Class TAP <CTRL-a>x<CTRL-b> &Thread_Depth / &Number_Size DRILL ( &Diameter ) <CTRL-a>x<CTRL-b> &Drill_Depth - ( &Pattern_No ) HOLE
NOTE: <CTRL-a>x<CTRL-b> must be typed in exactly as shown. "CTRL",
here, does not refer to the control key on a computer keyboard.
One final note.
You have to restart Pro/E each time to see the changes.
Best of luck,
J.W.
