'Curtain Wall' to join sloping glazing

[Damo]

This has got me stumped for the past 2 hours.

I have a flat roof with an opening, which I want sloping glass to the top and vertical galss to the side.

The vertical galzing is 'Curtain Wall: Exterior Glazing'
The sloping glazing is 'Sloped Glazing: Sloped Glazing'

I have tried to ATTACH the wall to the underside of the roof, but get the error message "There is a circular chain of references among the highlighted elements.".

Can anyone please help me on this?

I haven't had to do this in 6.1, but I vaguely remember there being a problem with what you propose in an earlier version (5.0 5.1???) I think you will need to select the vertical section and then use Edit Wall Profile. You can lock the line you use to cut to the roof structure so you will still be parametric.

I think the problem may be where the vertical section reduces to zero. If you raise the roof piece even by a couple of mm you may avoid the problem.

Attach a generic wall to the sloped glazing and change that to Curtain Wall: Exterior Glazing.

{EDIT}Now that I've tried what you are saying... I don't think that's your problem. I was able to join a curtain wall to the sloped glazing without issue. Give it a shot in any case.{EDIT}

Gem!
Went straight for this answer, and had it sorted in 30 seconds.

Thanks

Damian,

Your problem is excatlly as Peter has stated. You cannot attach a wall to a roof where either the following 3 rules occur:

1. A portion of the wall has a zero height.
2. A portion of the top of the wall is below the bottom of the wall
3. A portion of the bottom of the wall is above the top of the wall.

I have run into all of these problems and the only solution is to rais the roof to be attached about an inch or so. You may have to experiment with small increments to see what the smallest you can go before Revit errors.

After looking at your image you may want to consider making the curb part of the curtain wall so you will have positive wall height in all locations.

Perhaps you could also try using a Ruled Curtain System. But you would have to make sure that none of the conditions exist, that cphubb pointed out

that is -

1. A portion of the wall has a zero height.
2. A portion of the top of the wall is below the bottom of the wall
3. A portion of the bottom of the wall is above the top of the wall.

(Haven't figured out how to make part of someone else's message have the border around it)

Garn,

Check out your message (you can edit your own messages), I added the "code" to do the quote...so you can see it. But to do it yourself, just click the Quote button on the bottom right of a post.

Thanks PeterJ, Cphubb & Garn for your considered replies, and more so, for the explanation. I much prefer to know why something didn't work, rather then just the answers.

However, pushing for a deadline I first tried abauretts's suggestions and within 30 seconds had it sorted.

I had forgotten about the old "Make your window with a brick wall" ploy . Silly me.
