Beam System Floor + Architectural Floor ?

[Anonymous]

Hi, I've placed an architectural timber joist floor in my model - with a 200mm joist zone.

Separately I've also placed a Beam System in place with 50x200mm joists.

Can these work together ? I've placed the beam system and the architectural floor at the same level to show joists in sections, but it doesn't show in a 3d-cut away section (the grey rafter material in the architectural floor seems to take precedence).

Just wondering whether the 2 systems work together ? if not, what is the correct work-flow for adding a timber joist floor that also allows you to define and place the joists ?

The last way I tried was to define the architectural floor with a 200mm air gap, then use the beam system to fill that zone with joists - but ideally I wanted to place insulation in there as well - and that seems to over-ride the appearance of the joists.

A separate question on the beam system floor - is it possible to have a joist at the perimeter edge as well ? It defaults to having a space rather than a joist:

I want:

WALL:JOIST...void...JOIST...void...JOIST...

I get:

WALL...void...JOIST...void...JOIST...

I tried unpinning the individual joists and moving them, but that obviouslt just opens up the spacing of the first joist.

Thanks

rahter than making the floor object as an "assembly"  with a layer for joinsts/air/decking/etc. which Revit will treat as a solid, make the "floor" just the decking and/or the finish and have it sit on top of your Beam System.

There are properties for the beam system for "justification" to tell it where to start and stop, so you can make one of the edge joists "justify" to one wall.  On the other edge, you may have to add in a single joist along the other wall if the spacing doesn't "fit" pefectly.

graphic it seems that they can work together.....look in the attached image....one of the 3d  view in wich Parts were activated and the other 3d image is simple architectural floor. The beams (the border one and the Structural Beam System elements ) that appear in the 2 D section are also 3 d .

• check if your  Detail Level is not set on Coarse , because the structural element do not appear in it...you must have active Medium or Fine Detail Level selected  ..it is also possible that in some views structural elements not to be checked , so be sure that it is in Visibility Graphic Overrides.
• as I know the border beam has to be separately made.... Structure>Beam> select a beam or Load it from the Library ...Draw> Pick Lines> select the border of the floor slab...thus you can make the border beam different from the system type if you want...

Hi,

thanks for the pointers - I've redone the build up with a floor assembly for the floor finish+resiliant layer+timber deck - and placed that ontop of the timber joist beam system.

I then used a ceiling (plasterboard) to the underside of the joists - as you suggested that has left a proper void between the two layers that now doesn't appear solid (as the air gap did).

I tried adding 100mm mineral fibre batts as part of the ceiling assembly - and it now appears as I wanted it to - ie, between the joists rather than overlaying them.

OK - before posting this, I tried a few other things out - and I think a penny has just dropped - it's probably obvious to everyone else, but it only just dawned on me.

It seems that the order in which materials are 'stacked' - and therefore appear in views and renders, is dictated by whether they are part of the 'core' of an assembly, and whether they are designated as structure, substrate etc. In the previous problematic setup - I had the insulation included in the structural core layer of the floor assembly.

Thanks a lot for the pointers.

Hi Constantin,

the joists were appearing OK in the views - just not when rendered. The steps above seem to have cured the issue.

On you screengrab - where you have insulation shown as the batt linetype (the squiggles) - is that a call-out with that linetype shown - or did you get that to appear in the model / standard sections as well ?

Many Thanks

Martin

that squigle lines are only for 2d and it is from Annotate>Detail> Insulation...a very handy tool
