Rated wall pattern

yes_and_no — Thu, 29 Aug 2024 01:07:25 GMT

We normally use graphic line over wall center for this purpose, but the line won't move as the wall moves (locking it seems more work unnecessary).

I use pyRevit to make filled region pattern ok on plan, same size. But ít won't apply to graphic override. Perhaps i missed steps somewhere.

Anyone ?

Coarse scale pattern for coarse and cut pattern for medium/fine.

We use a key schedule to set our fire ratings for individual walls.

Then for our Fire Separation plans and building sections we have a filter that reads the Fire Rating Designation Value and applies a specific cut pattern override.

Your method involve doubling wall materials and wall type families which we
try to avoid (being R17, under 2GB file size).
I was talking about graphics override in VG or perhaps filters.

Hi @yes_and_no ,

If the Rated value is a parameter value in the wall, then use viewfilters to override the appearance.

"I use pyRevit to make filled region pattern ok on plan, same size. But ít won't apply to graphic override"

What doesn't apply to graphics override?

A non fire rated wall assembly and a fire rated wall assembly deserve to be in different wall types. That is why the OOTB Fire Rating parameter for walls category is a type, not an instance parameter. Adding a few more steel stud materials for different rating shouldn't increase the file size by any amount that should concern you. Think about a few hundred KB added to GB model. Big deals?

Using filters work graphically but filters come with their own can of worms. They are view / view template based instead of project based, so deploy them and modify them in the long run take more time and repetitive work. But yeah you will save a few hundred KBs.

Hi Toan. You are correct (as always).
There are myths about Revit that most people used to. "Using
graphic/symbolic lines are "not Rv way", "messing up OTB materials causes
Rv to crash"...to name a few.
While rated walls only been shown in one sheet (our STD), we incline to use
graphic Lines(1) or Graphic Override(2).
Given choice (2), do you have any suggestions/solution ?
As in (2) the wall currently can take solid shaded red color, I wonder why
can't ít take a patterned dash.

These are the patterns we use for our ratings.

;%VERSION=3.0
;%UNITS=MM

*0.5 HR FRR, 0.5 HR FRR
;%TYPE=DRAFTING
0, 0,0, 0,0.1, 0.8,-1.2

*0.75 HR FRR, 0.75 HR FRR
;%TYPE=DRAFTING
0, 0,0, 0,0.1, 5,-1.5,0.8,-1.5

*1 HR FRR, 1 HR FRR;

%TYPE=DRAFTING
0, 0,0, 0,0.1, 5,-1.5,0.8,-1.5,0.8,-1.5

*1.5 HR FRR, 1.5 HR FRR
;%TYPE=DRAFTING

Hi @yes_and_no,

"Using graphic/symbolic lines are "not Rv way" ... Don't know who says that, but using graphics overrides IS a 'Rv way'

Maybe in terms of BIM using detail lines and not giving the 3D elements that data or keeping that in sync, Yes I can relate to that.

"As in (2) the wall currently can take solid shaded red color, I wonder why can't ít take a patterned dash."

So with a Graphics override with color + 'dashed' pattern the wall doesn't get the pattern?

- Is Cut Pattern overridden? + is wall cut (I assume floorplan)

- Maybe the dashed pattern is to dense, check other viewscales

- View set to Detail level Coarse, maybe it overrides with the Wall's Coarse pattern? (Not sure if a ViewFilter would override it) anyway, set the view to Medium or fine. (or else just the wall category in the view/template)

"messing up OTB materials causes Rv to crash"...uhm never had a issue with this.

To make a fire tape pattern work with filter, edit the pattern and make sure it is set to orient with element, not view.

Per yr advice I successfully made the rated pattern appears in plan, including in PDF print.

One step up, how do I do this as a filter, without making separate wall type ?

Someone suggests doing a wall schedule with tags, that s counter productive, IMHO.

Re: Rated wall pattern

Mike.FORM — Tue, 03 Sep 2024 13:13:00 GMT

We use a key plan so that we get a drop down parameter in our wall properties that we can use to set several parameters. We then check our Fire Rating Designation parameter with several filters to set the correct cut pattern to walls, floors, ceiling and roofs. The Fire Rating Designation is a letter value and we also show this in our standard wall tags.

Hi @yes_and_no,

If you don't want to create Type per Rating, use a instance parameter.

I see @Mike.FORM post uses a key schedule to populate the instance parameters, if the rating includes more than one value use that as solution.

why are you not using the filter and pattern or line pattern ?

or use the line as attached details group with lock to the walls:
