Medeek Truss Plugin / Re: Development and Updates for the Medeek Truss Plugin
« Last post by Medeek on March 26, 2017, 09:51:41 am »
Version 1.8.7 - 03.26.2017
- Added energy/raised heels for double howe truss (3 variant: wedge, slider and vertical w/ strut).
- Metal plate connectors now enabled for double howe trusses.



Back to updating all the truss types with metal plates, raised heels and all other advanced options.

Version 1.0.9 - 03.25.2017
- Added slab foundation type (rectangular outline only).
- Enabled full and partial width interior thickened slab footings.

Version 1.0.8 - 03.23.2017
- Added crawlspace vent option to stemwall foundations.
- Added a "Materials" tab within the global settings; Auto material assigment (colors and textures) is now an option.
- Enabled materials for all foundation types.
- Added a joist pocket option for stemwall foundations.



I've been putting off the joist pocket feature for a while but figured I could spend my Friday night and knock it out.  I doubt it will get much use except for certain builders in the State of Oregon.

The options for the joist pocket option are:

1.)  Pocket Width
2.)  Pocket Height
3.)  Pocket Depth (into the stemwall)
4.)  Pocket Spacing (default is 16" o/c, but can be set to any value)

If you use joist pockets with either the brick ledge feature or the crawlspace vents you need to realize that the geometry must be such that the various item don't clash.  For example the stemwall must be thick enough for a brick ledge and the typical 2.25" depth of the joist pocket. 

With vents and pocket joists there must be enough vertical clearance between the two otherwise the header will be too thin for the overlying floor joist.  One solution to this problem is to have the vents only on the front and back walls while the joist pockets are on the left and right walls.

The number of options and inputs is now a bit mind boggling and the code is also at a new level of complexity.  Taking all of this to a polygon shaped foundation will be a challenge but that is where it needs to go next.

The vent module seems to be working fairly well:



If you set the top distance to zero the vents are right up to the sill plate:



Notice the top bar is clashing with the vent cutouts.

The options for the crawlspace vents (if this option enabled) will be:

1.) Width (in.)
2.) Height (in.)
3.) Corner Distance (ft.)
4.) Top Fnd. Distance (in.)
5.) Max. Spacing (ft.)
6.) Location:  All Walls|Left/Right Walls|Front/Back Walls
7.) Vent Insert:  NONE|PLASTIC|METAL

The Max. spacing variable will determine whether to insert intermediate vents along the wall line.  The module will always place two vents per wall (if wall line selected), one at each corner and then equally space vents along wall line based on the Max. spacing variable.

I am currently working on the polygon and line tool for both stemwall and slab foundations.  I am finding it hard currently to get enough time to really push ahead quickly so I don't have an ETA on the release of these tools.

Have you made any progress on drawing foundations per a plan yet? Currently we can only do rectangles :(

The ICC codes call out a minimum of a one vent within 3 feet of each corner.  It shouldn't be to much trouble to create the openings in the stemwall and place some vents:



For a rectangular building (4 sides) should I place 4 vents or 8 vents?  Provide only the openings or also provide a generic foundation vent (lightweight geometry?)

Moving an opening is actually very easy within SketchUp, when it comes to a solid wall like this.

What is the typical header thickness between the top of the vent hole and the top of foundation?

Vent size seems to be 16"x8" for most vents I've seen.

With regards to vents there are the cheap plastic ones you can get a Home Depot or Lowes and and then there are a whole ton of more expensive louvered metal manufacturers of vents and flood vents.
