Yes, yes.the simple answer is use color 254.
5mm I usually don't use this color but it at least DOES plot correctly. White (whether I use 255 or plain white) 2.1mm (would ordinarily be. I assigned the lineweights to greyscale.ctb as follows. My drawings are fairly simple and I only use a few colors. This is a fresh install on a brand new computer that should be well equipped to handle AcadLt and Revit. This is driving me absolutely MAD! Don't recall so much of a fuss going from 2005 to 2012. Any ideas to resolve would be appreciated. I can not seem to get color number 255/white to accept a lineweight assignment. I have always used CTB files/color based line weight system. Migrating to AutoCadLt 2020 and trying to set up my lineweights.
