Spray-on fireproofing

[JamesVan]

Has anyone here ever created spray-on fireproofing for steel structure the way AEC Details creates it for ACAD? I'm falling in love with 2D detail drafting in Revit :D , but require this necessary component...

Any help is greatly appreciated!

I would create a detail component using the diff. structural detail components as a base, use the pick tool to pick the lines of the element, then offset as required to create the thickness of fireproofing, finish sketch assign a fill type and then change the fill pattern of the original to none, then you can use it with the type catalogues assoc. with the item, ie wide flange.

or just draw a filled region around the item and send it to back so the other item hides its shape.

[JamesVan]

That's one solution, but do you think there's a way to develop the 'squiggly' line look of the fireproofing? See attached.

You might try using invisible model/symbolic lines offset at a couple of anges from your steel family, then lock splin points to the ends of the lines. That way you ought to be able to parameterise things.

How do this do? See attached image...This was quick so I'd be compelled to make the lines look a bit "better", but you get the idea right?

Left side of beam has "edges" of FP visible, right invisible...which is more betterer?

I saved as the detail component structural wide flange family, added the FP filled region locking it to the perimeter of the beam. You could conceivably just have the FP and make the entire beam invisible to put on top of a true beam cut in sections views??

Steve, I think we're on the same path. I created a copy of the W-Wide Flange family and put in the fireproofing. I set up the dimensions in the sketch for the filled region and created an instance parameter called "Fireproofing" so I can modify the thickness.

The FP flexes nicely with each family type, but when I try to change the Fireproofing thickness parameter, I get an error that says it can't make the type. Ideas?

BTW, I like your curvy edge better than mine. Have you attempted to 'parametricize' that design to the steel shape?

Anyone come up with a better way yet?

This thread is pretty old...

Hey James and Steve,

You guys are brilliant. Can you send me your files? I'd like to look into something...

thanksm

Here is a different idea
One image shows a single detail component that I put into a repeating detail...

The second shows it applied.

While not the best solution - I still have to touch up the corners, I can usually get pretty close.

This allows me to do details like floor connections where there is a beam, deck or some other member on top of the sprayed beam (fireproofiing then follows another element and does not form across top as if it got stuck in the wide flange family)

[Steve_Stafford]

...You guys are brilliant...aw shucks...fidgets nervously...:-) You give me too much credit certainly...I might be brilliant if I actually had the file still!! Did you notice the dates on those posts? Over two years ago, YIKES! That's like four PC's and two companies ago! Time flies!

Once, I had a user - new to Revit - who used the revision tool to create fireproofing. It looked great, but it's still a revision cloud.

I then created a parametric repeating detail component of the curved segments. The only drawback is that you cannot draw or pick arcs or splines to generate a repeating detail path. Imagine if you could select a repeating detail family in place of a linestyle - cool.

If the developers are listening: Modifying the repeating detail feature to pass in a dynamic (rubber-banding distance) value through the "Spacing" parameter would satisfy me.

You can go into the revision cloud sketch, sketch the fireproofing, select all the sketch lines, copy the lines to the clipboard, cancel the revision sketch, and do a paste align to your view. I've done this on a detail view and it works. The only issue is that you can't select those lines and change the style of it (i.e. change it to thin lines or heavy lines). I'm working in Revit 2011. Perhaps Autodesk will come up with a solution in 2012 for spray on fireproofing that is similar to the insulation tool.

Another approach is to start with the detail component structural Wide Flange family. In it I set up reference planes so what is normally the exterior of the steel shape becomes the inside if the filled region, and then a single factor of spray-on fire-proofing thickness creates the spacing of the outside lines.

No, it is not "rough" looking like we architects would normally want it to look, but once set up it is fast and easy to place. I just copied the txt file for that shape over to the new family name, and I have a fire-proofing family for every wide-flange size.

This is essentially the path James and Steve headed down several years ago.

I dont know about you guys, but i really want it in the family itself, with a yes or no checkbox for existance... because i want it modeled. Fireproofing can add a few INCHES to steel in all directions, and that can cause conflicts. Im putting it in our modeled steel library, IN our steel Families.

While it Does add inches, most consulting structural engineers feel that they are taking on added liability if they model the spray-fireproofing in their model. I personally don't feel that, but convincing them is tougher. Especially as we find more and more owner's demanding that we turn over models to the contractors, as a condition of getting the job in the first place.

No all of us work for a firm with all disciplines in-house like Aaron does now.

[twiceroadsfool]

I dont have Structural in house.

I guess what im saying is, if i was going to make a DETAIL component of it, i might as well just make a COMPONENT out of it, if they (the engineers) wont do it. You can even do a save as from the OOTB structural content, and invert the sketches to be a donut. Then you match up a W24x68 with a W24x68-FP. Youre then a Copy > Paste Same Place > Change type away from having it modeled, and having it in the right spot.

We are A and C, no E. :)
