Body length
This description is confusing for the new user.
Lets break it down as new users are learning this software. What they are probably assuming when reading the descriptions.
If you think about it, Body which means an "entity" the entire entity being a whole.
This would make the programmer think they are filling out an over all length of the tool.
If that description was changed to TOOL EXTENSION and it auto populated the set up sheet with TOOL EXTENSION.
This would be a huge benefit for the set up machinist.
And this will work across the board with Lathe as well.
