3D Truss Models
-
Just an FYI, some of the recent updates have managed to break a few things in the metric side of the plugin. I will be working on these issues all of today (and tomorrow if necessary) and release the fix later this evening or Saturday morning. I apologize for the inconvenience.

Version 2.4.7b - 06.14.2019
- Addressed a number of critical bug fixes for metric templates.
If you are working with metric units this update will address a number of issues that were not resolved when the edit function was added to various trusses and rafter roofs. This is an essential upgrade.

Still trying to get the complex roof module up and running but every time I try and refocus some other fire comes along and pulls me sideways. The soffit and fascia module introduced another block of parameters which need to be exposed in the global settings so users can set their default behavior, this is a relatively easy addition. I will knock this one out sometime later this evening.
With the Wall plugin I also have a huge list of items but a couple which are actively being requested are stacked windows and a custom offset parameter for the stud spacing. I really should hop back into the Wall plugin and try to address these before I get re-focused on the complex roof module.
The recent metric fix will be a welcome upgrade/resolution for many of you using metric templates. Again, I apologize for not spending as much time as I would like on debugging the metric side of the house. I will try to make a more concerted effort to check the metric side moving forward.

I thought my job is hard, imagine having to frame something like this up:

An example of "Just because you can think it and draw it does NOT make it worth constructing in the real world!!"

Version 2.4.8 - 06.16.2019
- Added a Soffit/Fascia tab to the Global Settings.
I've been developing this plugin now for almost 4 years. Progress is steady but much yet remains to be done. Once the complex and secondary roof modules are operational this plugin will begin to compete with the big dogs of architectural software (eg. Revit, Chief Architect etc...) Its taken a while to get to this point with a few detours along the way but I'm getting very close to accomplishing the holy grail of the plugin which has always been the ability to handle complex roofs automatically.

With the recent post about the foundation plugin (adding in parametrics for slab on grade foundations) some people are asking "Why did you stop working on complex roofs and move back to the foundation plugin?". As it turns out the algorithm or logic for editing the "polygon" outline of a complex roof or foundation is pretty much the same. Since I have the overall code in place for a slab on grade foundation I am first implementing the polygon face edit tool with the foundation plugin then I will bring this code over to the Truss plugin and complex roofs.

Could you kindly work through your code and ensure that when someone is working in metric they don't encounter any fields to be entered in inches (or the like)? I have version 2.4.8c and was using common truss, got to advanced settings, at the ceiling parameters and somehow ended up facing fields with inches entry requirements.

I will take a look at that. There may be a few advanced option menus that only allow for imperial entry. Off the top of my head I don't remember which one it is but I do recall that one of them still does not allow for full metric entry. Thank-you for bringing this issue to the top.
When you edit an assembly in metric are you getting any non-metric parameters coming up?
-
I get metric for the most part, just the advanced that seems to kick out into imperial.
Your Timber Truss option (bottom right) still doesn't accept metric at all.

I will look at this module as well. When I initially setup the timber truss module I thought it would be a big hit, but then I received literally zero feedback on it. I assumed it simply was not being used by the vast majority of users so I probably did not see any urgency to provide the metric side to this module at the time.
I will jump on it, and see what I can do.

The "FRONT" option for Gable Truss parameter allows one to terminate a truss assembly where it meets another roof or wall but currently it does not provide for a GIRDER truss as shown:
I need to provide an additional option here called "GIRDER" which allows the user to terminate the truss assembly and also configure a girder truss (ie. Howe truss with heavy bottom chord and stubbed off tails).
-
Version 2.4.9 - 08.27.2019
- Fixed the trim tool so that it is now able to trim hollow sections (ie. pipes, rectangular tubes).
The extend tool already had this ability but for some reason I was not made aware that the trim tool was unable to handle hollow sections until just recently.

Medeek Live Training: Session 2
Scheduled time is Sept. 12 (Thursday) at 11:00 PST
The primary topics covered will be the recent additions to the truss plugin (ie. soffit & fascia, asymmetric rafter roofs, etc...) however as usual I will be open to any other questions via the online chat.
The session should run about an hour in length depending on the number of questions I receive.
I think I've worked the kinks out of my streaming software, so things should go a bit smoother this time.

Working in earnest on the complex roof module today after spending about two months overhauling the foundation plugin.
As I'm putting together this module I'm starting with a clean slate and trying to take advantage of all my behind the scenes and UI improvements I've made with the updates to foundation plugin and even the electrical plugin. All of the menus for this module will be HTML. Many of the editing and move tools will be brought over from the recent work on the foundation plugin.
The basic parameters that will define the complex roof overall geometry and roof planes are:
- polygon outline (provided by a face or a locus of user selected points)
- pitch
- overhang
- birdcut
- rafter depth
Additional basic parameters will be:
-
rafter width
-
ridgeboard depth
-
ridgeboard width
-
hip rafter depth
-
hip rafter width
-
valley rafter depth
-
valley rafter width
-
framing option: Yes/No
-
advanced roof options
If the advanced roof options are enabled then the roof planes are actually further defined by the sub-fascia width since in two of three sub-fascia types the roof sheathing (plane) actually extends over the sub-fascia.
The advanced roof options will include: sheathing, cladding, sub-fascia, hip-and-ridge, gutters and soffit & fascia. The number of parameter required for all of these options is too numerous to list here. Future advanced parameters might include: gypsum, ceiling joists, heel blocking
Once a complex roof assembly is created it then can be edited by selecting various roof planes and customizing that roof planes particular parameters.
The roof plane edit tool will allow the user to adjust the follow parameters specifically for that roof plane or eave/edge:
- pitch
- birdcut
- rafter depth
- Overhang OR Delta Height (vertical height of supporting top plate)
Additionally certain roof planes will be convertable from a hip configuration to a gable configuration. Once a roof edge/plane is converted to a gable it will then need to be editable with a different "gable" menu, which will include a whole host of gable specific parameters (ie. outlookers, gable overhang, wall sheathing, wall cladding etc...)
Similar to the "Move SOG Edge" tool with the foundation plugin I will also have a "Move Roof Eave" tool that allows the user to move the roof outline around by picking an edge and dragging it perpendicular in or out. This should make resizing a roof a breeze.
I will also have the "Edit Roof Outline" context menu tool which will allow the user to actually edit the polygon that defines the roof outline.
I'm posting this update not only for you but also for me as it is helping me organize some of my own thoughts about what direction I need to take this new development. Any feedback or suggestions on what I have proposed thus far for this new module is very much welcomed.
Just to be clear this module is something I have been trying to accomplish within this plugin since I began coding it almost four years ago. This is the Holy Grail of the Medeek Truss extension. If I can pull this off successfully then I have actually accomplished something.

First look at the Draw menu for a complex rafter roof:
When you first click the complex roof icon you are first presented with the initial selection menu:
Once you click the rafter roof option you are then given the draw menu.
I now have the initial supporting infrastructure and templates in place, in other words the boring stuff (ie. attribute library storage and retrieval, draw and edit menus, polygon tool for point selection, global settings).
Now begins the much more challenging and exciting part of the development, establishing the roof planes and the actual geometry creation algorithms.
-
Bravo for the unceasing coding to the perfection!

First look at a complex roof primitive created with the complex roof module:
The roof primitive will be placed on the hidden layer and the roof outline (blue colored face) will be placed on the outline layer. The outline layer is important since it allows the moving of the roof edges. Both of these layers are normally turned off but can be turned on manually at any time.
View the model here:
https://3dwarehouse.sketchup.com/model/10c5d29f-eee3-4ff7-8fbc-0686d6e9bc16/Complex-Roof-Test-1
So far the algorithm for generating the roof planes (roof primitive) seems pretty stable, I will have to try harder to break it.
The next step will be the edit functions and then sheathing and cladding, those are the easy ones. After that it is on to sub-fascia, soffit & fascia and gutters.
The most difficult algorithms will be the framing and the hip & ridge.

First look at moving a roof edge:
Click to view animation:
Now I need to setup a similar system which will allow certain roof planes to be toggled between hip, gable, dutch gable and half hip. I think I will keep it simple and just start with the gable and hip options first.
Even with only the roof primitive this is already shaping up to be a fairly powerful tool. I like that the entire roof is parametric, I really dislike limitations, both for myself and for the designers who use my plugins.
-
You can also eliminate entire roof planes simply by merging the edges of the roof:
