Linked File Revit MEP has Colors

Revit MEP can assign system colors to their pipe and duct systems. It is easier for them than using a lot of Filters like was required in the past. If you are one of the other trades (architect for example) and link an MEP model and you see color it's probably because they are using this feature. This is what it looks like in the MEP model. I focused on the Domestic Cold Water as an example.

Now the file has been linked to an architectural model. The colors assigned to the pipe system are still applied to the elements. You might be tempted to try to alter the settings of pipe and duct systems in the Project Browser, IF you've noticed that your architectural template has them. I'll save you the trouble, it won't do anything to them.

If you don't want to see those colors you CAN override them with Filters.

I've opened Visibility/Graphics and then created a Filter. In the Filters dialog, if you select only the Duct categories, Flex Ducts, Flex Pipes, Mechanical Equipment and all the Pipe categories, then the "Filter by:" will allow you to choose "System Classification", set it to "is greater than" and "" (empty field).

This should catch all the mechanical elements in linked file and look like this afterward.

Remember to take advantage of a View Template to control this more easily and consistently.

Do you need to do the "System Classification" greater than trick? We suggest architects just leave it as "none".

We've also implemented other techniques in the past. In a worksharing project you can ask the architect to make a workset with the same name as yours, and filter by that same name. You can even use the "greater than" or "less than" options if you're brave (but that can be trial and error).

In a Filter? I'm not following your "None"... If I choose System Classification as the criteria I'm really just trying to catch any system so I can override the graphics. Using Greater than and " " allows for any of the classifications to be caught.

I don't follow the use of Worksets, that only works for loading or visibility?

I referring to how architects here (generally) don't model pipes / ducts, so they can just leave it as None:

With the worksets (
You can set a dummy workset with the MEP workset name that they use, for example - mechnical, and then make all of their mechanical items filtered.

Steve said...

Oh, sorry...blindspot.

Yes, both of those will work. It's more important to realize that we need to create a Filter, what criteria we choose is less so... leaving it set to is a bit "counter-intuitive" if we've bias toward choosing a criteria...but it does work since we're really just trying to select it "all", not worried about any specific criteria to separate anything.

Worksets...yes that would work long as they were diligent. I'd say the previous approach is more reliable.

troy said...

Ah yes I agree on both points.

It would be nice if simply applying a linked model as Underlay (in VV/VG) would make it all halftoned...

It would also be nice if we could say if "Workset" contained or "Begins with" as you can with other categories, but I guess that would make it too easy.

And for the record not all MEP engineers lack diligence ;)

Can we agree no trade is immune? :)

Hi Steve,
I understand there are 3 ways to set the duct or pipe colors: Color schemes, system type override and filters. Is there an hierarchy, what takes precedence on what? I think some light should be shed or the coloring/patterns behaviour or this can get really confusing and elusive.

Steve said...

Fotis - I'd say that graphics by System Type is the current primary method. Filters are second since they can be use to change things by view, to tell a different story. Color Schemes are an override to generate a specific (limited) kind of report. That's how I'd stack them... System > Filters > Color Schemes. Help?

Most helpful, keep up the great job,
