I am absolutely amazed by how much FOSS is actually already out there in the AEC industry ... it wasn't until this directory was started that I truly realised the extent!

Added PDAL
PDAL (Point Data Abstraction Library) is a C++ BSD library for translating and manipulating point cloud data. In addition to the library code, PDAL provides a suite of command-line applications that users can conveniently use to process, filter, translate, and query point cloud data.
And MDAL
Mesh Data Abstraction Library (MDAL) is a C++ library for handling unstructured mesh data released with MIT license. It provides a single data model for multiple supported data formats. MDAL is used by QGIS for data access for mesh layers.
When mesh data was introduced to QGIS it was a whole new data type (beyond the usual GIS vector and raster).
Here is a good overview:
https://docs.qgis.org/3.10/en/docs/user_manual/working_with_mesh/mesh_properties.html
I haven't found a good way to get my raster or vector data into a mesh format to really utilize the possibilities.
Not sure if they both should have been in software development because they are libraries but I put PDAL in the Scanning and Processing section because it dealt with point clouds.
Next GDAL

Meanwhile, since that Github issue was closed I've made a new one: https://github.com/ladybug-tools/butterfly/issues/406 ping @bitacovir and @nikitron who can hopefully fast track it. If architects get to use Ladybug tools in Blender, that will garner a huge amount of interest, I believe.
Hi, @mostapha
If any tool can be installed with pip, we use sverchok - extra repo with own nodes. If sverchok has no deps, sverchok-extra have dependences and allow installing libs directly into blender python directory by one button.
Never used this lib, so not sure what to start with.
For now i'm trying to implement genetic algorithm into monad and have some difficulties concern to this task. So, if someone can handle sverchok-extra implementation, we are wellcome.
@baswein the interesting part to me in the lecture you shared was about "histories" because I shared the same idea for IFC through using IfcOwnerHistory but maybe I couldn't explain the approach as simple as possible that everyone could understand
@ReD_CoDE I agree with you it is very helpful to know where the data came from and how it was created and I wish QGIS had a similar feature to SAGA. GIS data often has metadata and QGIS has a metadata editor https://www.northrivergeographic.com/archives/qgis-3-2-metadata as well as a processing history log https://docs.qgis.org/3.10/en/docs/user_manual/processing/history.html but the processing log is not automatically added to the metadata.
A heads up that the OSArch wiki now lets you contribute without an account for convenience :)
It also asks you a fiendishly difficult set of questions before able to make any changes for inconvenience ... for the inconvenience of spammers, that is - of which I've just had to block about 15 spam accounts and bulk delete all their trash.

Isn't there a plugin for anti-spam detection? For instance in wordpress there is Akismet...
@bitacovir yes, I have also set up anti-spam plugins. As with most anti-spam, you kinda set it up, see how it goes, tweak it if it doesn't work well, and continuously monitor. The captcha question is one of those tweaks.
Just stumbled in here, maybe I miss the point, but when it comes to environmental analysis in blender: what about VI-Suite (https://blogs.brighton.ac.uk/visuite / https://github.com/rgsouthall/vi-suite06) ?
Certainly more modest in scope than ladybug-tools, but probably nearer to usable state (in blender, of course).
And IMO SolveSpace (http://solvespace.com / https://github.com/solvespace) - although not very active recently - still looks appealing when it comes to parametric modeling.

wow! I did not know this one. Even it is running on Blender 2.8
@khad I completely forgot about vi-suite! I didn't know it was updated for 2.8.
Those look great! Can you please add them to the wiki? You don't need an account to do so :)
Good to hear about Ladybug from Mostapha and VI-suite from Khad. I've been using the following tools, free to use but not open source. Not exactly a software package, but the author of Ecotect has recreated some of the tools online:
urban massing and daylight studies
http://andrewmarsh.com/apps/staging/shading-box.html
input room geometry and weather files, exports to local and loads settings from local, dynamic daylight analysis, exports Radiance, DIVA/DAYSIM files.
https://drajmarsh.bitbucket.io/daylight-box.html
sunpath projection for given location, exports SVG
I believe vi-suite can accomplish the same as those online tools - should do some online tutorials sharing about it!
I saw before some of his projects and I like what he does these days, especially related to web viewer, this shows that he knows about the near future
Indeed, he shares his practices publicly, but in reality, tries to solve the whole puzzle ;)

These tools are beautiful, thanks for this.
My Urb::Field::Occlusion module has some over-optimised and completely unvalidated code to calculate sunlight hours and overcast CIEsky daylighting using occlusion masks and raytracing.
@brunopostle I like your projects, especially when I see some articles about pattern language from 2011! It seems that it's procedural! Something like Shape Grammars?
Do you have a recent demo?
@ReD_CoDE The part of Homemaker that places roofs, doors, windows etc.. is entirely procedural.
The building layout model is a similar kind of thing to shape-grammars, though it is more like binary space partitioning (I must have spent too much time building Doom levels); but the system for designing building layouts is entirely evolutionary, so not at all procedural or parametric.
I'm a bit slow at demoing the software, there is a recent output (in IFC format) attached to this discussion from a couple of days ago. The nearest thing to a description of the current state of Homemaker is this long Twitter thread.
@brunopostle sounds great when you mention it's entirely evolutionary, and yes, I understand why you mention why it's not all procedural or parametric.
ODA File Converter (opendesign.com) turn dwg into dxf

I don’t see any mention that it is FOSS. Have you seen a license file and source code somewhere ?
Edit : FreeCAD wiki specify that is freeware not FOSS.
It is not FOSS, only a "free" tool.
freeCad rely on it to import dwg, and it is a "known to work" solution to turn .dwg into .dxf - batch process
EPANet - https://www.epa.gov/water-research/epanet
Development - https://github.com/USEPA/EPANET2.2
EPANet is awesome - it works out pipe sizing and equipment selection including water tanks and pumps. Far easier to use and infinitely more abilities than Revit's rubbish hydraulic calculations.
@Bedson that's very cool! Would you mind adding it to the Wiki?
