Hi,

Did somebody know how to apply a wall cut hatch pattern by instance???, same type wall in different location but with a different hatch pattern.

Thanks

Alberto

Not sure why you would want to do that, but here's what you could do if you have to:

1) Set a filter for those walls based on an instance parameter of the wall (i.e. Mark).

2) Override graphics for that instance through right clicking on the element (this is not able to be tracked if you decide to change it later).

Though these methods would work I would question your reasoning for doing this once again. Are you trying to do this to show fire rating? If so I would reccommend these be different types. HTH

Hi CRWINCHESTER,

Yes this is for fire rating and instead to be creating the walls with a set rating I rather change the rating by instance. please help

Thanks

We have never found a good way of doing fire ratings using a hatch pattern.  Nothing seems to work well so good luck and let us know if you are successful.

We typically screen all of the model elements and add heavy detail lines over the rated walls.

I think we will be looking at other options now that our printer says they will do color printing for basically the same cost as B&W.  That will then allow us to use a solid color fill for rated walls.

What I've done is create a seperate wall type and build up the assembly as normal, but include a special hatch to symbolize the rating. Then I would have a regular or no hatch for course scale views. Utilize the Fire Rating parameter in the type properties for these walls that you create and that way you manage the visibility of the rating hatch using filters applied within your view templates. You may ask, why not just apply fire rating hatches to those wall types that use ratings with the filters instead? For some reason, and correct me if I'm wrong out there, there is a glitch in Revit where, despite being set to orient to object, hatches applied via view filters fail to orient correctly. You're left with few options after that. But hopefully that helps.

my office uses different line types for different fire rating hours. we always try to keep our drawings in black and white as we know often drawings are scanned and copied on site and thus colours tend to get lost which is not technically our problem but it is a possible cause of confusion so we do not do it. Also we put text beside all the fire rating lines stating the hour and we have an instance parameter within our wall tags that we can indicate fire rating by indicating A, B, C, and so on each which corresponds to a legend that has the correct fire rating hours.

We use different hatches at mine as well. If you need something really specific you could try an add-in called "Hatch-22." This helps create patterns more easily without writing the code in a text file. We do something similar with tags, but again this is done as type parameter rather than instance. I would still err on the side of creating these as types rather than instances. I would find that easier to manage and more explicit for users working in the model. But whatever floats your boat. Good luck!
