The "slash" terminator comes close to the architectural office standards I've had to use. Some standards have the slash mirrored in the opposite direction (ie \ rather and / ) but all have had slashes that had a heavier lineweight than the lineweight of the dimension/witness lines. It should be an easy fix to add some control to the lineweight of terminators - especially slashes.
[Strangely ... the back-slash (\) and forward-slash (/) on this post are not "boldable". Maybe it would be more difficult than than I thought?]
