First look at the output of the Stair Module:



Note, that only straight runs of stairs will be available for now, however it is possible to create L and U shaped staircases just by combining straight runs as shown and framing in a landing.

I will probably need one more day to fine tune it completely and finish adding in the hanger board and landing tread advanced options.

Future advanced options will be landings, hand rails, skirt boards etc...

The stringer algorithm is really the core of the module and drives everything else.  The logic was not nearly as complex as I initially thought it might be, regardless it was a blast to work through it and turn the math into reality.

On a related note I just noticed John Brock's new book has been released:

I think this will be a seminal work on incorporating SketchUp into the residential design process.  I've already gone ahead an pre-ordered my copy. 

I think I have the asymmetric truss roof figured out but shop drawings from a manufacturer would be helpful in confirming my own conclusions.

Version 0.9.9l - 11.16.2018
- Added an option to include 2D wall geometry in 3D modes (Framing, No Framing, CMU).
- Added an additional layer for 2D geometry.
- Added customizable colors for labels, 2D wall geometry, and 2D features (windows, doors, columns etc...)







The custom colors for the labels, and 2D geometry is per a discussion with a client today.  Hopefully this upgrade will help facilitate bringing the 2D geometry into layout for creating floor plans.

Does anyone have any shop drawings of an asymmetric hip truss set they can send me.  Specifically I am looking for a hip truss set that has different pitches for front and back and then possibly a different pitch on the ends.  I have my theories on how such a truss set should be put together but it is worth the effort to study this a bit further and verify.

I've recently been thinking about the multi-pitch hip roof again.  Eventually I needed to return to this topic since the designer needs the flexibility of assigning different pitches to the various roof planes.

The same issues with multi-pitch hip truss sets applies to rafter roofs as well.

When you have a hip roof situation and the pitches are different on adjacent roof planes yet you want to maintain the same overhang and line up the fascia then the wall top plate must change.  However with trusses rather than change the top plate you simply have to raise the heel of the truss on the low side until it equals the height of the adjacent side.

I been thinking about putting on a weekly one hour webinar where I can demonstrate the latest features of the plugin and then take additional questions from the audience.  Would there be any interest in this?

Some of you may have noticed the difference in the way materials are handled between the garage doors and man doors.  The method being used in the garage door module is the new and improved method.  I will be updating both the man door module and the window module to this new system which incorporates the materials in the Custom Material Library.

Also at some point I need to switch the draw door, draw window and draw garage door menus to HTML.  As always, never a dull moment and way too much to do.

Version 0.9.9k - 11.15.2018
- Added the ability to import materials directly from the model within the Custom Material Libary/Manager in the global settings.
- Provided an additional parameter in the Wall Corners tab of the global settings for setting the thickness of corner blocking (3 and 4 Stud Block corner treatment only).



With this latest update the tutorial on the Material Manager is somewhat out-of-date/obsolete.  However the basic functionality has not changed, I've really only added one additional action.



The ability to customize the blocking on these corner treatments was per a request from one of our Australian clients.  I've added a tooltip in the global settings to more fully explain the usage of this parameter.

Now back to the big items on the list.

Version 0.9.9j - 11.13.2018
- Added the following corner treatments: 3 Stud Solid, 4 Stud Solid, 3 Stud Block, 4 Stud Block, U-Cal
- Enabled a parameter in the General tab of the global settings to toggle the labeling of groups.



I also addressed some minor issues with the way blocking and insulation interact with the corner treatments.  Its seems I have that ironed out now and much less likely to generate geometry that clashes. 



I don't know how commonly the U-shape California Corner (U-Cal) is used (shown above) but I really like the fact that it offers more nailing surface for ext. trim and siding.  I've had a few requests for it as well, so being as it was not too hard to include I added it in.  There are now seven possible corner treatments for walls, the other two are California or None.



I typically like to name all of the groups I create within the assemblies however there may be some who do not want this behaviour and so I have made it optional.

For wall corners I will be adding in the following additional corner treatments:

- 3 Stud Solid
- 4 Stud Solid
- 3 Stud Block
- 4 Stud Block

When the user sets the number of studs for the corner on anything other than one, that setting will override the corner treatment for the above corner treatment types.  However this is not the case for the California corner (however I may change it in the future if it makes sense to).

These algorithm can get a bit complicated due to the number of permutations possible when you start mixing up corner treatments and multi-stud corners for shearwalls.

The problem I find with California Corners is that it does not provide very good backing for ext. outside corners when it comes to siding and trim.  However it certainly is better for insulation and much easier on the electricians.

There does not seem to be any hard and fast rule on the length of blocks used but it seems to average between 12"  to 14", so I will set my algorithm to a max. block length of 14" .  So for example a 96" wall will have four blocks at 13.714".

Currently in the plugin I have only implemented the California Corner (as we Americans call it) or Energy Corner for corner treatment however there are number of ways to handle corners.

https://design.medeek.com/resources/framing/FRAMING_CORNERS.pdf

I have been requested by a potential client to enable the following corner type: "Solid corner with short blocks".  For a deeper wall sometimes two rows of blocks are used (2x6 wall) rather than one.

I can implement the solid corner however I need some more information:

1.)  If you use blocking rather than a full stud how do you determine the length of the blocks and the number of blocks in a given wall height?  Is there any rule of thumb with this?  I just need to come up with a reasonable algorithm.

2.)  Is the blocking typically the same dimensional lumber as the studs?

Technical discussion about groups vs. components here:

This is related to the way I am handling certain elements such as studs, blocking, insulation and other arrayed building elements.

Version 0.9.9i - 11.10.2018
- Added angle iron (L) beams to the beam module.
- Added fillet radiuses to wide flange (W) and universal (UB) beams.



Nine different beam types with two series of wide flange beams (W and UB).



Aside from residential structures one could also use the beam module to create various structural steel assemblies, however that is not really the purpose or target audience for this module.

I added the fillets to the wide flange profiles per customer requests.  The primary reason for including this information it to better predict and check bolt patterns that are on the web of the beam(s).  Fillet radiuses are per the various standards.

I haven't take the time yet to add in the few hundred standard sizes from my steel manual but as time allows I will continue to populate these fields.  Also if there is specific requests for sizes or series of beam types I will accommodate those requests.
