This release contains numerous enhancements to MGED's mirror command,
now with the ability to mirror an object across arbitrary vectors or
points along a standard axis. Additionally, nirt now has a new "gap"
option for reporting the empty spaces between objects on a given
shotline with additional formatting options under development.
The release also has a new procedural database geometry tool called
'tire'. This new tool was developed by Cliff Yapp for the purpose of
creating highly detailed tires based on user-provided specifications.
Given standard tire dimension information, the program can generate a
corresponding curved sidewall tire on a fitted wheel and that has
detailed tread. The results are impressively realistic tires.
