Export New and Exist layers from Revit to cad

[Anonymous]

I am playing around with layer mapping in Revit. I can easily modify the layers to export to Autocad. In autocad, we use exist and new layers. (M-Equip-exist, M-Equip-new). Is there a way to associate the layer mapping to the phase in revit? Thank you in advance for any assistance.

I don't have {Phase Created} option, I'm using Revit 2016. Any suggestions?

You do have that option unless something is wrong. Review the steps again.

Got it, it works. Thanks.

Hello, using Revit 2018 

I'm using Phase Created with many different systems. Each Phase must be a certain color. How can I force the color ID for the modifier to overwrite the category ID color?

thank you

As you see, I have assigned a color ID to each phase. I left the color ID blank per category.

It seems to work here - Revit 2017.2.3.

I'm looking into Materials as well per pipe type. 

here is what i'm looking at. Using Navis to cache out the dwg. As you see, my Phase Created modifier works yet you see one that is D? For whatever reason, all my Pipe fittings are on that one. Even tho all of them are on the current phase per revit properties.  The green/blue pipe, all should be color 94 (the green one) yet the blue accessories and a few elbows are blue. All same phase. I'm completely stumped.

I edit the material to be the same color as I placed in the export settings, it worked. 

Now why those elbows are going on a Layer "D" is beyond me right now. They are all on a phase. 

thank you for repsonding

When I tested the elbows and accessories are in the correct layers in AutoCAD.  But if you edit block an elbow you will see the geometry inside the block belongs to a layer different (D?) other than the layer of the block itself.  I suspected Navisworks reporting the source layer instead of the block layer so you see D instead of the Phase Layer. 

In the CAD realm, geometry inside a block should always be in Layer 0 and Color By Block but I guess Revit programmers do not belong to this realm.

Sorry for the very late reply but I did manage to get it to work as I wanted.  the layer modifiers were applied to the blocks within the "master" block. I had my cad guy update a command to fix that post export and it works great. No more "D" layer

Ever tried to export a file with the phase status and the layer just doesn't include that modifier? I have a model that is purely existing and when I add the modifier for phase status, the layers just show S-GEN instead of what I was expecting like S-GEN-Exist...
