Graphite is an in-development raster and vector graphics package that's free and open source. It is powered by a node graph compositing engine that fuses layers with nodes, providing a fully nondestructive editing experience. https://graphite.rs/
OSAFE Workbench (FreeCAD addon) https://github.com/ebrahimraeyat/OSAFE
The OSAFE workbench by Ebrahim Raeyat. This FreeCAD Addon is a collection of civil engineering tools, originally designed as a workaround for issues with CSI SAFE. The addon is available via the regular Addon Manager.

Just reviewing this thread regarding OS and Free software. Although not specifically AEC software but for myself and others that plan to record video tutorials and post edit, Blackmagic offers a world class video editing application called Davinci Resolve. Fantastic application and very open community.
Free and open source NURBS Modeller.
License: BSD https://ayam.sourceforge.net/
Ayam is a free 3D modelling environment for the RenderMan interface, distributed under the BSD licence.
The current stable version is 1.33, released 25. Jul 2023.
Ayam currently runs on Unix (Linux, IRIX, FreeBSD tested), Win32 (Win95-Win2000, XP, 7), and Mac OS X (Aqua and X11).
Ayam features at a glance:
RIB (RenderMan Interface Bytestream) export and import.
Support for NURBS curves and (trimmed) NURBS surfaces, Boxes, Quadrics (Sphere, Disk, Cylinder, Cone, Hyperboloid, Paraboloid, and Torus), CSG, MetaBalls, Patch Meshes, Polygonal Meshes, and Subdivision Surfaces.
NURBS modelling includes approximating and interpolating curves as well as extrude, revolve, sweep, birail, skin, and gordon objects with caps, holes, and bevels.
First modelling environment to support Subdivision NURBS.
Custom objects that may freely implement their representations (using OpenGL and RIB) and even small GUIs to edit their type specific parameters may be written by the user and dynamically loaded at runtime.
Scripting interfaces: Tcl, JavaScript, Lua; Script objects.
Misc: instancing, arbitrary number of modeling views, object clipboard, independent property clipboard, console, n-level undo.
File formats (r/w): RIB, DXF, 3DM, 3DMF, OBJ, X3D.
