I can honestly say I've had next to no experience with manual drafting (well
school but that doesn't seem to count anymore). Is this standard still
applicable to dimensioning in the base file? How do you compose the dimensions
if you don't know where one viewport ends and another begins? And as to the
"art of dimensioning..." you're right but I still (as I'm sure you do) think the
basics can be thought and it seems that so many of the people that I work with
have either forgotten or never knew to begin with.

The variable you'll need (in case I haven't mentioned it yet) is DIMLFAC. Set
it to your scale factor. It will multiply the dimension AutoCAD finds by the
scale factor and report that number... so 1" in ps at 1/8"=1'-0" (scale factor
96) will become 8'-0". Pretty slick. I don't know how accurate it is but if I
ever catch one my architects dimensioning below a 1/2"...

No... I use the standard linetypes from AutoCAD with the occasional new one
thrown in for fun. I just let the scale factor of the viewport control the
scale factor of my linetype which will work as long as PSLTSCALE is 1.
However... when I need a viewport in the same file as my line work (no xrefs)
then I set my PSLTSCALE to 0 and my LTSCALE to my DIMSCALE same as you (if I
understand you correctly and if I don't then I'm throughly confused).
