Thanks to the Mechanical development team for making this a reality
This has been a minor annoyance since my first use of the application back in the days of Mechanical Power Pack 2000 (hence the carryover of the initials of that name in the default profile <<AMPP>>). After a three year hiatus, I started using the application again (in 2007) and made this request. Six years later this request was honored.
It is interesting that in the years since I requested this feature I have been not employed as a machine nor tool and die designer.
I hardly use Mechanical's powerful features like this spiffy new version of the centerline command. Instead, I now am a process designer and use third party plant design software and use its commands (running on top of Mechanical).
Things change...
