I have a layout that has two viewports. One vieport contains line drawings to print B&W. The other viewport has a simple 3D model with applied textures and simple lighting. When I choose monochrome for plotting, I get the lines in B&W but the model in full color. Is there a way to force the model to print/plot in grayscale rather than full color w/o having to make changes to the model? If I chose shaded rather than rendered in the plot style, it somewhat achieves the look - but the model is a small case with a glass door and the glass then renders as opaque.
My understanding is that plot styles (CTB or STB) are only used for 2D Wireframe, and that other Visual Styles all plot using the drawing color (or, where materials are applied and active, the render material). I suppose you could set up a Display Configuration/Display Representation Set(s)/Display Representations and Material Definitions that would assign all linework to be black/white or one of the gray colors and to have black/gray/white render materials. That would be a lot of work.
Yes - too much work for this small project. But I can see the need in the future. I would also need the grayscale to be able to handle the transparency of the glass materials as well. One workaround (though I hate having to do a workaround when a product should be able to do it) is to render the image out, run through Photoshop and make grayscale, then bring back into Autocad as a JPG. But that means repeating that process for each change in the model. Yuck.
I wonder if I could define a new model "material" paint as a gray tone and apply it to the model? But that would still leave issues with the glass. But since it technically has "no" color, it might work. And would it REALLY print as gray - or be a "colored" gray?
