Help with footing

Anonymous
Not applicable
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.

Regards

The Answer to "clean" intersections in the Section window usually is the matter of what fill pattern is associated with the objects (Wall, slab, beam, etc..) If you want the objects to be seamless at the intersection, they must have the same Fill pattern in the Section. Make sure that the materials that are assigned to the "footIng" (regardless of the tool used) and the "stem wall" have the same fill pattern.

Thanks for the response. Will that work if one object is a beam and the other a wall? Or between a wall and a slab?

I usually use the slab tool for footings - very quick w/the magic wand. You can set up a pretty complicated hoouse w/lots of jigs and jogs and pony walls etc... in just a few minutes.

Tom, interesting concept. How do you easily control the width of the slab?

if u are using a simple / 90 degrees / straight / continuous footing like the one shown below, i would use the slab accessories under 'extras'...
everything else is a pain cuz u need to re-do everytime u move a walls/slabs

Assuming the foundation walls are already placed, I magic wand a slab around the entire perimeter, then use the offset option at one of the nodes to offset the the slab from the outside the required distance. Then, magic wand the interior of the slab as needed to essentially cut holes in the slab. Finally use the offset option again to offset the slab from the inside of the walls.

Rereading what I just wrote - doesn't sound exactly clear. It'd be easier to show than to explain w/words! My method is admittedly sometimes not quite as easy as it should be. depending on the complexity of the footprint and varying heights of setmwalls etc... - I usually end up manually dragging a few slab nodes around and adjusting some offsets manually.

Tom,

I think your method is the most flexible and reusable way to do footings. I have seen a lot of methods, and either slabs or walls works best. The Accessory is nice sometimes, but has its limitations as well (though the CADImage one is a lot nicer, it is still not quite as flexible as I would like).

My only problem with using slabs is that if you show them dashed on plan, they dash in your sections as well!
