I was just sitting here thinking, how good quality are the plans you have anyway? It might not be a bad idea for you to totally redraft the space, based on your own real measurments, essentially make your own as-builts, instead of relying on potentially inaccurate plans.
also, great experience with VW drafting, its what I did a few years ago to get used to the spaces I'm in now. even drafted it up in 3D for the practice. this way you can do plan and elevation views when designing. helps everyone.
just a thought.
Also if you are looking for the 6" fresnalite, i couldnt find it either. But if you use an
altman or some other fres it should be just fine. also you can revert to the
USITT 1990 folder which has the standard stencils in it. FS3 is a 6" fres.
