Help with footing

[Anonymous]

I (not unlike other people, I think, based on my review of previous posts) am having trouble with creating a simple footing. I have tried using a wall element for the stem and another wall element for the pad. The problem with that is that the hidden line looks good in plan, but should not be hidden in section. The best I can come up with (besides the "footing" in the slab extras is a using the beam tool. Problem with that is the corners of the stem become clipped, and in section, there is a horizontal line between the stem that should not be theres. Any help would be greatly appreciated.

im looking for a solution for the following issue:

how do build a foundation footing/basement wall with an interior
basement wood wall WITH WINDOWS. i can place windows in the basement
wall, but there is no corresponding opening in the basement foundation wall.

any suggestions?

Lindsay,
I am guessing that you are using a library part to be the
basement wall and footing. Maybe you are using the slab
accessory "Footing". You can't put windows and doors
into the side of a library part.
Make your basement walls with the wall tool.
You can then put openings into them.

I have been experimenting with a library part that
makes footings and it seems to show some promise.
It is stretchable and the miters and joints are made quickly
with 2D editable hotspots.
Independent control of how it appears in plan, section/elevation,
and in the 3D window is easily done.
Offsets, asymmetric footings, independent line types, pen weights,
sloped sides, e.t.c. can all be coded for.
I submit that this option has some merit.
Thank you,

The library part solution does offer a lot of advantages for AC9.
In AC10 it will be less so (or not at all in some cases).

Hello Matthew,
Are you permitted to say in what way in AC10 it
(the advantage of the lib part approach) will be less so
(or not at all in some cases) ?

The complex profile walls can well be used for the footing walls in 10.

Maybe this is what Matthew referred to?

Continuous footings are essentially cast in place beams. The beam tool makes the most sense for continuous footings and one which I logically used when I started with the program. I have found that using the magic wand on radius walls to place the "beam" footings does the trick pretty well. I have found that tracing the "Beam" footings on a separate story with the foundation walls ghosted keeps the operation clean when you need it. You can always copy and paste back to foundation wall story later and set elevations as required.

A simple routine to allow a beam and wall to be joined would work quite nicely (in most cases)

Joining multiple wall types without the use of composites would be a great feature as well, especially when you consider that a real building would be constructed in the same manner thereby crating real world BIM.

Looking forward to version 10 arriving!

I've really found the "Beam" tool to work great for footings. You can show them as hidden lines in plan view, and solid in cross. Also the elevation is measures off the top of the beam so I just have the elevation set to "0" on my foundation story. Whenever I need to change the height of my foundation wall, I change the story height and the footing moves automatically. Of course you have the exception when you won't want the footing on the "0" line, but for the most part it works really well. Magic wand works well, when you set up the beam offset number so the reference line matches up with the foundation line.

I have two reasons to use slabs. Walls don't allow different appearance in plan and section views (dashed w/ out fill in plan - solid w/ concrete fill in section). The second reason I like slabs is the that level dimension tool can use gravity to show the footing height as it steps on a sloped site. Depending on the project, I will use slabs for the stem walls for the same reasons. The profile wall in 10 seems to hold promise, but it would be nice if graphisoft gave us control of how walls look in section versus plan. In addition allow gravity to work with walls such that the level dimension tool can measure the tops of walls and for that matter any element we place in our model.

The reason I use walls is they are easy to link to property objects. I keep various sizes as composites linked to appropriate property scripts including rebar. A 24" footing w/ 2#5's... a 30" footing w/ 3-#5's etc. If you don't pull material take-offs now, you might later and having this in the file (which might become a template for something else) might be worth it. You can still magic wand them, add to your favorites, etc. I personally see no reason for a "speciality" tool. All the above also applies to the wall on top... you can make several composites for poured walls, containing rebar scripts, block sizes containing stucco, web reinforcing, PT plate.. whatever.
