I mean offsetting complex shapes in one go.

Just randomly throwing together an example:

I don’t even mind the UI that much,

Agree to disagree.

From what I remember something as common as offsetting lines in a sketch required switching away from the sketch workbench into the draft workbench and exiting the sketch editor altogether.

FreeCAD feels like it’s where Blender was before version 2.8. The core functionality is there but the UI feels almost user hostile.

This is a list of all the open source software I have come across and use frequently to semi frequently. There will likely be some overlap with stuff everyone has already posted.

Photography and Image manipulation

• Darktable → RAW photo processing
• GIMP→ Photoshop alternative
• Krita → Digital painting (have only used it a bit, but I hear it’s good)
• Inkscape → Vector Graphics
• Automatic1111 → Diffusion model AI toolkit (mostly Stable Diffusion but also has extensions for other diffusion based models like OpenAI’s Shap-E)

3D modeling and Printing

• Blender → 3D Modeling, sculpting, 2D animation, compositing all rolled together (simply one of the best examples of FOSS)
• Meshroom → Photogrammetry
• PrusaSlicer → 3D printing slicer based on Slic3r

Video editing and Processing

• Kdenlive → Genuinely good video editor
• FFMPEG → Command line media toolkit (very complex but also works on android through Termux)
• Instant NeRF → Neural Radiance Fields, think photoscan to a 3D representation (not meant to make 3D meshes unfortunately)

Misc

• Calibre → E-book management
• Serge → Self hosted Local LLM’s made a bit easier to deal with
• Firefox → Web browser

FOSS I’m excited for

• DragGAN → Manipulate images by intuitively dragging, more on this here and here (official code being released this month but there are already projects based on the paper with working examples)
• CoDi → “Composable Diffusion” Any2Any conversion Txt2Vid, Vid2Audio, Audio+Txt2Img, whatever
• Neuralangelo → Promises to be NeRF’s for 3D models (don’t know if it will be FOSS but I’m hopeful)
