When I am modeling structural steel sometimes there are existing members I am connecting to so I will draw them to add some clarity to whoever will be reviewing these drawings. On my drawings I will hand select each line of the existing materials and change the line color to grey so they will stick out from the rest of the new steel. Is there a way to do this automatically with the custom property I have set up? Maybe link the material from my part file to a specific layer in my drawing document? (See screenshot below)
