Create Custom Hatch Pattern or use Detail Lines?

[PhilvK]

I have walls that have one tile pattern on the lower portion, then another from about 4' to ceiling. The patterns are not standard Revit patterns. Is it simpler to just use detail linework on the interior elevations, or is it relatively easy to create a new and custom hatch pattern?

Even if they were they standard Revit patterns, how would you do 2 different patterns on the same wall, paint the face?

how complicated is the hatch pattern? you can make simple custom "Hatch" patterns fairly easy. If you start getting into offset or different shapes it can get a little trickier. but I would just use a Split Face on the wall then Paint. 

for a wall tile situation... make sure you use a Model vs Drafting pattern. otherwise the pattern may shift or scale on you in different views.

If you want to create custom patterns easily, try pyrevit plugin

[stefan_gokstorp]

you can also import the PAT file from autocad by creating new pattern chosing custom and browse 

the autocad patterns should be located here C:\Users\YOUR USERNAME\AppData\Roaming\Autodesk\AutoCAD 2022\R24.1\enu\support

@stefan_gokstorp  I use this all the time .... i thought that only works for Drafting Patterns though. As a best practice, i usually copy the pattern out of the AutoCAD .PAT and make one for Revit. Then you can add the Model and Drafting ";%Type=" header to the pattern so it behaves properly in the model.

Instead of one Wall, why not model the wainscot (the lower portion) as a separate, overlapping Wall Type of the thickness and material of the actual finish materials. 

Regarding surface pattern: simple and legible is my mantra. Don't go crazy nuts with hatching linework that will only muddy up the view and distract from more important linework.

It sounds like you are doing finish tiles for a bathroom or similar? I would not split face or paint, those are hard to track/change for design changes in the future, in addition to future users being confused why patterns aren't updating on a wall. The split face tool is good for selective uses, but over-use causes lag and bloat in the file - so its semi-never used in most offices from what I've seen.

What is typical is a separate wall type with an acronym or parameter that has "FW or Finish" etc in it. That way you can filter them easily if needed, for example in the overall architectural plans and only keep them on for enlarged. This wall is placed via your standards and just 'laminated' on top of the partition wall. You can then keep partitions fairly simple types (limited number) and just for structural purposes.

If its a consistent height off the floor, I'd put both finishes into one wall, so you can control them globally. You can use a stacked wall for this super easy (its kind of built for this purpose). I personally never use stacked walls, so I would probably muscle the basic wall to do it  --- if you edit the assembly, click the preview flyout, then switch to section, you can add sweeps and all that jazz to the wall.

You can use Pattycake for (free) live preview editing of the patterns as you custom write some. That was the original intent of the software --- instead of needing to write it, then load it into CAD or Revit to 'see' what it looks like.

I agree with simple, and for now, how about something simple as duplicating an existing pattern and using it? I need a running bond 6" x 12" but can't find a way to edit the basic 8 x 16 pattern already in Revit because I am using it elsewhere for concrete block. I feel stupid asking, but how do I go about that?

[hmunsell]

Here is a 12x24.... you should just need to edit it and cut the numbers in half 🙂

*Tile_24x12, Tile: Modular - 24 x 12
;%TYPE=DRAFTING
0, 0,0, 0,12
90, 0,0, 12,12, 12,-12

*Tile_24x12, Tile: Modular - 24 x 12
;%TYPE=MODEL
0, 0,0, 0,12
90, 0,0, 12,12, 12,-12

[barthbradley]

What about duplicating and scaling the existing?  Change Import scale to 0.75. 

8 x 0.75 = 6

16 x 0.75 = 12

6x12

[PhilvK]

Thanks so much! Where do I save it so Revit can access it?

[PhilvK]

That's what I tried to do, but am not successful in duplicating it.

[hmunsell]

where ever you keep your other standard content :-). Revit doesn't really care. When you pick Custom, you Browse to select it.

Huh? Are you duplicating the existing Brick Material and then editing its Surface Pattern to Duplicate and scale the Pattern?  

[PhilvK]

Yes, your process is what I wanted to do but I was missing the duplicate button. Thank you for that!

By the way, how do you include in a reply a quote from the message you're replying to?

[PhilvK]

hmunsell - I would like to put new patterns with the standard ones, but cannot find that directory. Where is the standard PAT file located for Revit please?

[barthbradley]

Use Transfer Project Standards to transfer Materials (including their Surface/Cut Patterns) between Projects.  

[e.koehne]

Definitely use pyRevit’s Make Pattern Tool. Also, use the split region option in the wall assembly editor. Split face and paint work fine in RFAs, but become problematic in RVTs. Google rules. Practice makes perfect. Just keep fiddling with the tools until you perfect them.

[PhilvK]

I went ahead and created my own PAT file with notepad. Thanks to all who responded, they all helped.

For forum purposes, do you mark all the responses as 'accepted'?
