Hello, my DWG is set to monochrome.ctb. Everything prints ok except my 2 isometric 3D viewports which prints in its real color (visual styles are conceptual). Why don't they print also in monochrome? I saw a couple of discussions on that problem but the "hidden" and "hidden 3D" options in shade option isn't working...I want them to stay the same, just print in monochrome with screening! I read about some option called "hidden legacy" but can't find that anywhere...
you can control the indexed colors for AutoCAD (1-255) with CTB, you can't control true-color values. And that said all visual styles doing some type of rendering (and hidden-xxx also use the render engine) produce true-color appearance and can't be converted by any CTB-settings.
The only chance I see you have is if you have a driver to your output device that can be set to output the content as monochrome, then this driver converts the RGB-values (or CMYK-values) as shades of grey.

What version of Map3D are you using?

This is what i'm talking about: the 2 viewports on the left get "influence" by the monochrome.ctb (which gives 173 and 175 colors different levels of screening). But the isometric views (conceptual style) on the right, prints with the real colors (173 and 175 being purple) and not influenced by the monochrome ctb...Why is that? What can I do so the they print the same grey as the ones on the left?
>> But the isometric views (conceptual style) [...] and not influenced by the monochrome ctb
Because they are shaeded/rendered and so they are display in true-color. True-color can't be controlled by CTB.
The only chance you might have is to set your printer-driver to monochrome/greyscale as the driver calculates then the shades of grey, but AutoCAD can only convert it's 256 colors from ACI (AutoCAD Color Index)
