DB - Spread/Isolated Footing
« on: September 26, 2007, 07:13:08 PM »
Anyone seen a DB for a spread/isolated footing? I am attempting to make an all(mostly) encompassing DB to handle numerous spread/isolated footing situations. I have attached a dwg(v2007) as an example of possibilities.

Any help or ideas is... as always... greatly appreciated.

Thanks

I haven't seen one but I haven't been looking for one either.  You can try looking over at the Augi site.  They have a big collection and may have what you are looking for.

Are you just looking for a block or are you asking for someone to build this for you?

If it's built, no need to reinvent. I am pretty sure that my limited experience with db's will make this an interesting one to get done.

Take a shot at it, then post back with what you've been able to do.  That's one of the best ways to learn how to do for future DBs.

Here is a footing part. Pretty basic. I have started to create some typical rebar types and am doing ok with them so far, but to make a type 2/17 is a daunting task. What I have found is that I make each of the bar sizes(geometry) in different areas of the drawing, add all of the params/actions, move everything to a base point and then modify the cpolygon areas and such. So... for a type 2/17(I say 2/17 because they are basically the same shape and for details, it works. So... a type 2/17 has these configurations: AB & ABG

--

Shaped like a the letter C.

Sizes: 3 - 11, 14 & 18

Dimensions: A(leg always present), B(always present) & G(leg on/off)

All have wipeouts via the use of a polyline that matches the geometry of the bar, except at the arcs which I created a polygon with 128 sides and offset 1/128" to the inside of the geometry. Once plotted you can't even tell that there is that small offset. It is visible on the screen as a sloppy looking line. hahahaha.... I haven't done it yet, but I figured if I put the wipeout polyline and the wipeout itself on the defpoints layer I would not ever have to worry about it not plotting as defpoints is hard coded into the AutoCAD database to never plot.

I used visibility states to define the legs to display.

I also played with using a non-plotting dimension to have a visual on the size as I stretched it. Not sure that is a good way to go.

I can't remember if I updated this one to stretch all legs whether on or not. I seem to remember having issues with that... some error.

--

So far I have sizes 3-8 and I stopped there, but can't remember why. hahahahaha....

I shall post for the sake of sharing and VERY welcome critiques.

Can you save them down, I can't open them in 06

Just for the heck of it, here's a DB wall that I've created (still needs some tweaking) that is intended to be a starting point for a wall detail.  I know it doesn't help you with your issue, but I figured I'd share it since it has to do with structural.

Well, anyways... here 'tis.

dwg v04

I think they're going to be useless in '04 because '04 didn't have DBs.

v04 is the same file format as 06.

dwg v04

Instead of drawing all those different actual geometry sizes, look at a block using lookups.  Look at the steel beam shape in the Civil tab of the AutoCad tool palette.

As if you have any questions.

Ahhh....but even so, he's got '06 which doesn't have DBs does it?  Weren't they introduced in 2007 (I can't keep up with what came out when).

Look at this simple light block for what lookups can do.
