We’re happy to announce the guidelines for Eco-Libre’s new logo!
This section will outline some metadata about the logo above
The text “Eco-Libre” is written in the font Lato Bold
If our tagline “Libre Tech for Human Rights” is added, then that text is written in the font Latin Modern Sans Demi Cond Semi-Bold

This release concludes the manual merge of the contributions from volunteer Jack Nugent. It includes CAD designs for the self-cleaning, raw surface water intake and sphinx documentation.
🛈 Note: Just want to build it?
This article describes a historical "release" of this project (a snapshot in time of our CAD designs and documentation).

Part of the difficulty in completing this merge was the fact that the Eco-Libre Life-Line’s intake system includes expanded metal as a support structure and a fine mesh for preventing debris from entering the raw water intake drum.
Modeling these materials in FreeCAD caused the MemSize to bloat, crashing FreeCAD. In the past month, Eco-Libre founder Michael Altfield published two articles that described the process to isolate these troublesome objects and how to optimize them with a Draft Hatch. These optimizations (as well as simplifying objects like threaded bolts pipes, valves, and steel angle) reduced the total MemSize from 114.8 MB to 1.02 MB.

In our last guide, we looked at how to get a granular view of the size (in bytes) of each layer in a FreeCAD file — so we could figure out which object was causing the file to be so large and slow. We found that 90% of the file’s (uncompressed) MemSize was being caused by just one item: a 95 cm x 68 cm sheet of Expanded Metal.
Unfortunately, rendering mesh objects (like Expanded Metal) in any CAD software can cause enormous lag in the app.

This article will show you how to find out exactly which layer is causing your FreeCAD file to balloon in size, by getting a granular list of all of the layers in your document tree, sorted by size.

Recently, we had a volunteer who made some very helpful contributions to the Eco-Libre Life-Line project — an open-source design for raw water intake, filtration, and storage system for sustainable communities.
The original file was 812 KB. After the changes, the file was 17 MB (compressed). And — worse — manipulating the objects in FreeCAD was now very slow and choppy (spoiler: the uncompressed size was 114 MB).
Before merging the updated objects into our GitHub, I figured that some optimizations could be made to reduce the file size — to make opening the file in FreeCAD much smoother. But which object should I focus on optimizing?
You can see the size of each layer by pasting a small python snippet into FreeCAD’s python console.
