Framing Roof Problem

Anonymous — Wed, 04 Aug 2010 03:35:21 GMT

Using Archicad 14

My framing is attaching to my roof membrane and is keeping my roof framing from gavitating to my top plates. I need to reverse the roof membrane with framing.
I use the roof wizard which works perfect, except the fact that its on top of the roof material instead of underneath resting on the plates like it should be. If I turn off the roof material layer, roof framing still does not drop to plates.

Does any one know how to fix this, or suggestions how flip this around. Would very much be appreciated!

Somewhere there is or at least was a place to set the roof thickness, or perhaps I was dreaming
In the meantime with grouping enabled, in the 3D window it is easy to drag the roof framing assembly down/up into the correct position.

The roof timbers lock onto the bottom surface of the roof you selected.
There is no way to change this as far as I know.

I guess it is designed for a roof composite that has a thickness to allow for the roof timbers (air space) with the cladding skin on top.
When this is placed on your wall plates the roof timbers will end up in the correct position and the cladding skin will appear to float over the top of it all.

Barry, The roof timbers did not lock under roof materials, but locked on top, should be the other way around, right.

This is what happens when I use the roof wizzard.
Maybe it's just an Aussie "down-under" thing

Once placed the timbers are just objects which you should be able to move around at will.
They are no longer associated with the roof plane.
You can even delete the roof and the timbers will stay.
Do you have the layer that the timbers are in locked?

Barry , Well I was able to delete and redo roofing material to sit on top of timbers as I wanted, but still have'nt been able to extend wall plates to bottom of of timbers, its as roofing material is still there. Walls will not stretch up. or timbers will not lower? I could try to delete walls, but would like to know if there's another way.

Thanks ry

I'm not sure why you are having trouble stretching or moving items.
Walls you can just chenge the height in the info box or grab the top node in 3D and stretch it (choosing the correct mode in the pet palette).

You shouldn't need to delete the roof - you should just be able to move it up or down in 3D or elevation/section or by adjusting its height in the info box.

Can you cut a section through your model to show what you need to move or stretch?

Ry,

I would guess that you trimmed the walls to the roof. Trimming operations remain intact until undone. To undo the trim select the walls in question and open their Settings Dialog. Part way down (near the material in AC 12, not sure where in 14) you should see a button that is marked Unto Roof Trim. Click it and then click OK. Your roof trim will be no more. Reselect the wall and desired roofs and do the trim to roof operation again with the roof(s) in the new location.

While there is plenty of use for the trim to roof function, you may want to explore Solid Element Operations (SEO) as well. This will do much the same thing but the result is dynamic in that the trim location will move with the movement of the various elements used for the SEO.

Using SEO is better to trim walls IMO since it follows changes made to the roof.

Generally this is true.

However, as long as you know how each function works and the advantages and disadvantages of either then you can make the best choice. There are times I want a trim to stay unchanged with model changes and other times when the dynamic action is best. Also too many SEO's in a model and you will take a big speed hit.
