Face Based Family won't host

651 Views, 16 Replies

My face based Air Terminals will not let me place them in the current project I'm working in.  When I try to place them, I get an error that says "Couldn't find an appropriate Host.  Try selecting a different Host Face or switch Placement Mode."  I have used them in 3 other projects with no problems.  Any idea why I can't get the ceiling to host them in this one?  Would it have something to do with the way I have the View Graphics set up for the architectural background?

 

Thanks

Jess

I presume you have ceilings visible in the view and that they sit within your view range and cut plane? Are you placing in floor plan or RCP? If floor plan - try using a ceiling plan to place them

I do have ceilings visible in VG.  Already checked that.  I am placing them in an RCP view, not floor plan.  However, I did try to do it in a floor plan when it wouldn't work in the RCP.  Didn't make a difference.  I've checked my view range & cut plane as well.  I am within the correct limits.

 

Thanks,

Jess

Is it just that family that won't find a host? And in the View in which you are inserting the family, make sure that the host is visible (and isn't just a hatch pattern or something) - tab through the link elements and make sure you can see it.

Just found a resolution for this problem.  Went into the Link's VG and turned off all categories under the Model Category tab EXCEPT ceilings.  This worked.  I then turned ONLY the lighting fixtures category back on so I could center my registers between them, and suddenly the ceiling won't host my registers again.  So it appears to be something with the light fixtures that the architect has in their model.  I can work with this.  I'll just place my registers, then move them after I turn the fixtures back on.

The reason for this behavior is that the architect's lights are still cutting holes into their ceilings, and since there is a "hole" there, you cannot host anything to that particular spot. One of our early solutions to this was to create Generic Ceilings to host our elements.

Even though it's not just that hole, but the entire ceiling that won't host my family?  And if that's the case, then why will it host my family when I turn the lights off?

You're right, then. There's another issue going on there. If you end up finding out any more info, please post. I believe I have heard of this before, and I'd like to know the reasons...

Thanks for figuring that out, we are having the same problem.  Even tried hosting in a 3D view and had no luck.  If you figure out why this is happening please post.  I'll be looking into it to and will post if I figure anything out.
