Individual material line types

[Anonymous]

I am trying to change the line type of only one material in a wall. We want to represent our 1-hr rated fire wall(2 layers of cmu blocks and fire stop material)  with different line types for just the 1-hr material. For example, (Solid lines for the CMU blocks), but (Center lines for the 1-hr).

If you use filters even with and/or conditions it still changes the line types for the whole wall. Override graphics in view does the same thing by changing the whole wall not just one material. If you do common lines then all walls with multiple materials will change. You can change the line type by selecting the lines representing the edges of the 1-hr material, but you have to do that in every view, because they don't carry over to the section views. 

I created a new hatch pattern that looks like the line type we want in a .pat file, but you have to make a horizontal and vertical pattern depending on the orientation of the wall. From all the posts, forums, YouTube videos it doesn't seem possible, because walls are system families. We have 2018 and I have tried it on my 2019 version, but no luck. We are upgrading to Revit 2020 soon. Does anyone know if this is possible with 2018, 2019, or 2020?

In AutoCAD I would just write a lisp program and be finished, but I do not know enough C# to know whether it is possible that way in Revit. Any Help would be much appreciated.

The Photo with all black lines is how we'd like it to look, but the photo with the red lines is all we can do.

I don't understand the issue. Are you unable to create materials with a different cut patterns and assign it to the wall type? 

...ah! I think get it! Because the pattern runs parallel with the wall, not perpendicular to it. So it's not parallel with both horizontal and vertical walls in the project. Is that about the size of it?

You could use linework (LW) command to adjust the lineweights as you like. Does require some manual work though.

edit: you could create 3 layer wall and adjust the common edges cut line pattern? that might work. edit 2: probably not gonna work, as I guess you wanted that for this specific wall type, didn't think of that just now...

You cannot change "By Default" the line Style/pattern  only on 1 face/side of a wall/part of wall. Those are 3D elements.

What you could do (some options)

1. Use dynamo to place detail lines (as per the color/pattern style  you choose) at the center of the wall (the ideal solution I have used)
2. make use of the Foreground and background cut patterns  the material
3. place those lines manually or use line work to override the line pattern on one side of the part/layer
4. Use parts and override the cut line pattern of just that layer

This is an annotation task really I guess. Probably quickest to just do that, but you could ofcourse also choose a different way of showing these walls (color/hatch override ie.?)

@martijn_paterit might not be the OPS's case but in some countries it is a drafting/graphic representation standard required by certain authorities when submitting for the permit …

Here for instance we have something similar to what the OP has described for fire rated walls. FR walls must be designated with the line of specified pattern (dash dot/dash double dot/dash triple dots) color (red/blue/yellow)  running through the center of the FR walls...and they will reject the building permit if it doesn't comply with their specified standard (99% of the time they do not settle for alternatives)...Dynamo was there for the rescue though

Reading the first part of your response, pardon me if I'm not interpreting
it correctly. I am trying to change that line type/weight for all the
views, but only one of the materials. I.e. on the plan view, it would show
the solid lines of the outside face of the wall and a different line type
representing the fire wall. If you take a section of the wall it would show
up the same way.

Currently we just drawing a model line, but we have to do that for every
wall. Looking to have set it up with our company template, so when we draw
the wall it is already there. I am not experienced with dynamo, but I will
look into it more.

correctly.

I am trying to change the line type for only one of the materials, not the
patterns. For instance if you drew a wall, on the plan view, it would show
the solid lines of the outside face of the wall and a different line type
representing the fire wall material. If you take a section of the wall it
would show up the same way. Our standards require a specific line
representing a firewall to be shown so everyone knows exactly what type of
wall it is.

I am uncertain if it required for permitting, but that is exactly what we
do.

We want to have it set up in our template so it shows up that way when you
draw the wall. That specific (line type/weight) is the FR material in the
wall would and the outside face of the walls would remain solid lines. If
you take a section of the wall it shows up exactly the same way. Only way
to do currently is to draw it in on every FR wall.

@Anonymous  I do not believe there is a way till date which lets you automate purely in Revit. The best way to do it so far is using dynamo to place model or detail lines at the centerline of the walls...

The is one way to fake it in Revit which I do believe I mentioned above and that is to use Wall parts on the Fire and life safety layouts and set a Parts Filter to override 1 material in the wall...looks close but you would still not be able to change the pattern of the common line with the adjacent materials...see below... (what is marked in blue cannot be filtered separate from one another)

I haven't heard of any other way to do  what you are asking better than in dynamo....maybe Autodesk will consider adding a feature that makes the wall center line visible with option to set pattern weight and color

Maybe you  can get partway there through Cut Line Style Overrides.

That is what thought. I hoped I had overlooked something. I will start
playing around with dynamo and see what my bosses think. Thank you.

Unfortunately it does it to all lines, not material specific lines.

That affects ALL compound elements of the view...while fire rating is rquired to be applied on to 1 wall type (ex: just the fire rated ones) 

[barthbradley]

Oh, I see.  You might be able to get there by turning the walls into Parts and using some Rule-Based Filters. 

Interesting challenge. I got to gnaw on this one a bit.

Definitely. I'm new to my firm and they've tinkered with it via older
version of revit fir awhile now, but I've put in a good 40 hours of my own
time, because it's killing me. It seems like it should be easy, but it
wouldn't be as satisfying if it was easy.
