I'm an archicad software user, i have a question for you regarding the Slab Accessory - Under Footing Settings..
I want to find the way to stretch the footing size, i did explode it, but it didn't work please tell me if there is another way to resize the footing...i was ungrouping the Object to stretch out the Object, but i couldnt do it...Please let me know how to re-adjust it.

First ... since this is my second PM in two days from new forum users with theretofore zero posts: I don't get paid to do this. So, please post your question on a forum addressed to the world at large. If you post directly as a PM to me, I'll assume you want to hire me as a consultant (I am a hired gun - I do not work for Graphisoft) and will need to bill you up front. 😉

Rick,

The slab accessories, like all accessories, are applied by selecting the element first (the slab), then the accessory. The accessory will then morph itself to match the slab (or wall, for wall acc'y, etc.).

The Footing object is not hot stretchable. All parameters are set within the object settings dialog (see screenshot). You can adjust stem wall thickness and height, footing thickness and height, plate dimensions, etc.

The names of the parameters are a unfortunate. The screenshot shows the SE library version. What they call 'footing height' is what we call 'footing depth'. What they call 'thickness' is what we call 'footing width'. (Ditto stem wall dimensions.) Slowly, GS is customizing the US library to better user US terminology ... but looks like none of us reported this one.

If you explode any AC element - object or otherwise - it turns into 2D lines and fills. It will no longer be 3D. This has uses at times, but is not what you want here.

You cannot ungroup an AC object into subcomponents either. An object is an element. You can only alter its appearance via parameters (or solid element operations when necessity calls).

Hope that helps ... post any more questions to this thread. 😉

Regards,
Karl

He just didn't realize that you are two of the smartest guys here!

And, yeah, when I said 'nobody', I assumed that the others who got a PM had deleted it from their inbox and were as senile as me. But, the rest of the guys are young and bright like you two and no doubt still have memories. 😉 So... we'll make that 'almost nobody'.

I feel your pain brother, but quality is better than quantity right?

It's a great community - I am just happy to be a part of it!

Cheers,

Sorry to be off topic (re. the number of post by the upper elite key peckers), and I am not worthy with my sub 200 post, but I don't use the accessory for footings.

I use a simple one piece composite, actually several of them... 18", 24" 30" 36" whatever. You then can attach a property object to those collecting the yards of concrete and the amount of rebar. You can pre-set the actual footing depth at 10", 12" etc with your template and/or favorite pallet. Drawing is simple, it's a wall.. so it will stretch if needed along with the wall(s) above.

(what am I now...nearing 200?:)

I have to agree with Rick. Using composite walls is a much easier way than fighting with the accessory a lot of the time.

[Karl Ottenstein]

Ditto. I never use the footing accessory. I always use composite walls (with reference line offset) for continuous footings and columns for isolated footings.

I think that the more tricky footing is the one with sloping sides. Until solid modeling came along, was this was best done with the roof tool? I've used the solid modeller and it is a bit tedious, but OK. Are there easier methods?

I ended up making a special library part that shows the beam/slope setdown and the section of the wall that sits in the edge rebate.
the good thing is iwth a few editable hotspot you can change the size while in section

I've found the roof tool to be amazing for thickened slabs and haunches on foundations. I especially like it since it does not require SEO to work, so it takes less steps to perform.
