Highlighting lines for construction?

Is it possible, with AutoCAD P&ID, to easily have lines (including their associated valves, etc.) be highlighted for plotting? -How easy is it to do it, if it's possible - what are the steps?

You might want to check out this tutorial on using color dependant plot styles:

I probably wan't as clear as I could have been about what we're trying to accomplish. -As an example of what we're trying to do: We have many distinct process lines in each drawing, each line has its associated valves, tie-ins, etc., and we need to somehow accent just one particular process line with its objects when plotted. (e.g. shade the line with a polyline perhaps, putting the polyline behind the line in the draw order) In some cases, we'll be plotting the same drawing multiple times, with different lines highlighted, and all others not highlighted. Long and short, we need a way to have the lines stand out from the others when plotted, instead of spending a lot of effort highlighting each target line with a clumsy pline and then removing the highlight before the next plot. -Is there an easy way to accomplish this with AutoCAD P&ID?

I agree with Jason, I would look at having different plot styles, so for one plot style, you might say anything that is cyan, plots heavier, then for another plot style, anything that is green plots heavier, etc etc.

I have the same question, and the answer that is being pointed to is not what I'm looking for.


We want to be able to highlight different systems in different colors, as requested from a client/vendor. So far I have been going through as needed and creating polylines on a non-printing layer and hatching them on a printing layer. I vary the hatch color from system to system and have the plot style .ctb set to plot specific colors of hatch to different colors, with the rest of the drawing remining black.


Is there a way to make process lines automatically have hatch around them, ie. via project setup? Our drawing set has 70 drawings, so automation would be a huge help!


I will attach a couple pictures to show you what has been done.

Thank you for posting that, along with the illustrations - that's exactly what we're trying to do too. (and basically how we're doing it now as well - with a lot of manual effort to set it up)
