How to convert Index Color to True Color without changing plot style?

Anonymous — Wed, 27 Feb 2019 22:16:11 GMT

I want to know if it's possible in model space or in viewports, to select a portion of my drawing or my entire drawing and change each index color to true color? for example, change blue color to this color: 0,0,255 !! or change yellow to this: 255,255,0

Color Properties changes can be done anytime you want to do them, but CTB plot style tables totally ignore TrueColor settings so that would be your only problem (not an issue if you are using STB plot style tables).

I have attached a drawing that comes with multiple colors. I want to keep the colors as they are (blue remains blue but in true color) but change them from index color to True color in my drawing. Please notice that everything is exploded and that's why it's not easy to to just select them and go to properties and change color.

I've has success with using True Colors with CTBs. Only on a few occasions I have had a True Color revert to one of the colors controlled by the CTB. A simple edit of the true color mix fixes it.

You can use the QSELECT command. Set object type to Multiple, set properties to color, set operator to =Equals, set Value to a color and hit OK. It will select all the entities with that color. Then go to the properties palette go to color and choose select color. On the select color dialog just hit the true color tab on top and then hit ok. It will change those entities to true color. You will need to repeat for each color you want to change.

What you explained is not what I wanted but it's very close and will work for me. Appreciate your time writing the process. Accepted as solution.

If you don't want the selection to be from the entire drawing you can also hit the button to the right of where it says entire drawing in the quick select dialog box and then make a selection of objects to work with.

If the object colors are ByLayer you can override the layer colors at the viewport with True Colors too.

I want to select objects and change their colors to true color all at once, in one single attempt (I don't think it's possible). I usually come across exploded drawings which are converted to DXF from PDF files and they are mostly under 0 layer with different colors (all index colors). Even hatch and solid shapes are exploded into tiny pieces (as attached file) and it's really annoying to pick each single object and change its color to match my plot style. If I change my plot style to acad.ctb and "use object color" in the plot style setting, it will screw up the rest of my drawing in the very same sheet.

But QSELECT is a very nice approach as you suggested and much quicker way to handle this situation, but still annoys me to QSELECT almost 20 times to change colors. I'm not sure if I explained it well and I hope you understood what I meant. Cheers,

I understand what your saying now. That could be done with a lisp routine. If you were interested in using lisp I'm sure someone could write one pretty easily to do that if you posted in the LISP FORUM
