Foundation Plugin
-
And where do you set the floor height from. Usually I end up working out what is best at the rear of the garage and sloping from there.

Here is a quick study on a garage slab that slopes 3" over about 24':

What to do with the slope at the garage door? I've flattened it out but that leaves a line in the slab.
At the side door entrance the right side of the slab is about 3/8" higher than the left side. Entrances that are parallel to the slope will have this property (problem?).
At the rear of the garage the slab is 6" below the top of the foundation and at the garage door it is 9" below the top. Perusing through different plan sets I've collected over the years this seems pretty typical for the slope (1/8" in 12").
I think I should probably make the slope an option so those that want to model it can.
Rather than make the slope a percent grade or degrees I think it would be easiest to let the users specify a total rise or drop for the entire slab.

I was playing with the Dibac plugin a little bit today and I really like the wall creation tool or how it works when selecting the 2D wall layout. I think I can program something like this for stem wall creation (polyline) that would allow the user to select any random stem wall layout. I've pretty much got it worked out already but I'm trying to figure out how to do that little trick with the tab key which allows the user to toggle the wall justification. Any hints would be appreciated.

I've been investigating attributes today trying to get a better handle on this aspect of SketchUp. I've noticed that the housebuilder plugin creates a category called "einfo" and stores a number of variables one of which is the "origin". If you manually move the wall group the origin attribute will automatically reflect this change in location. This is exactly the feature I need for my various assemblies (groups) so that I can add an edit feature. Howevever, I can't seem to figure out how this attribute is automatically updating. When I create an "origin" attribute under a "einfo" category it does not update. I must be missing something.

Try asking those questions in the develops section, I'm sure someone there would be able to point you in the right direction. Most visitors (including me) that frequent this section (and others) would not be able to even comprehend what you're referring to.

The current home designer I am working for likes to use 2x4 bearing walls versus a post and beam system in their crawl spaces:
I am wondering how common this method is and if it is something I should add into the foundation plugin as another variant.
-
Crawl Space - Access
Suggest an "access opening" in the stud spacing for any future inspection or maintenance.
Centre location would be logical, miss one stud and design support for floor joist. -
For a stud wall your right you need access doors or openings. I will make another function that lets one place the opening after the fact, that way they can be located by the user.
-
Does anyone have any details showing the access door through a strip footing and bearing stud wall. I have one here but I would be interested in seeing what others use so I can determine the most popular way of framing this up and then implement it.
-
What I've done in the past (and seems to work the best) is simply frame it as a door opening (36" or 48") with a 4x4 (or 4x6) with the top flush with the double top plate.
-
Something like this?

Medeek,
I am curious about the "white" membrane, is there to be a concrete slab poured?
If so what was the construction sequence?
If it is a moisture barrier how is it protected? -
Nathaniel -
Yep, that's basically it (though I've also see the top plates lapped into the header as well).

Version 1.0.3 - 08.28.2016
- Enabled interior bearing wall(s) with strip footing.

I still need to enable the ability to add framed openings into the interior stud walls. Interior stud/bearing walls can be created with single or double top plates and can be full span or partial spanning as shown in the image above.
Also note that the studs are aligned from the right side of the stemwall foundation edge so that they line up directly under the floor joists.

My new job has kept me away for the last few weeks so that getting anything done on the plugins has been a real challenge. Even so I've been giving some thought to stepped footings/foundations and would like some input from the designers and architects out there on what is common practice and what they would like to see available for this sort of feature within the plugin.

Note that I messed up on this model the exterior cripple/pony walls should have only had one top plate so that the combined top plate from the shallow sections and the single top plate would have created the typical double top plate.
-
One question I've had is how much should the stemwall overshoot the step in the footing before stepping down itself? I've seen different ratios used (ie. rise/run) but I'm trying to find a consensus on what is common practice.
-
A typical step in the footing might look something like this:
-
I've repackaged the .rbz file this evening so that when it installs into SU 2017 the extension will have the appropriate hash file and appear as "signed". The foundation plugin may have the same issue with hashed file as the truss plugin, however it does not in any way affect the functionality of the plugin.

Version 1.0.4 - 11.27.2016
- Enabled rebar and mesh reinforcement for slab on grade foundations.
Footing reinforcement is #3 - #8 bar.
Slab reinforcement is welded wire mesh or #3 - #5 bar.
European metric sizes are available in the metric mode.

There are quite a few options to play with, rebar size and quantity. Notice in this example I've used #3 bar for the slab reinforcement rather than the mesh and I've doubled up bars on top and bottom of the footing (#5 bars):
On a related note does anyone have a good texture for rebar that they would be willing to share.
