when i create a linetype including a text, i want to different color from line the text
because when i try to print out, if line color very thick (for instance 0,5) linetype inside text doesn't appearance
no can do... that's not an ability of Autodesk's line style abailties.
two option -- you can explore using MLine - bearing in mind it's limited and has not been updated in dog's years/ Or, change to a TTF font for the text in the linetype. Since TTF are outline fonts rather than stroke fonts. they plot out ignoring lineweight, and are simply legible at any size..
