Oh I’ve never heard about that one …
The problem with Davinci I encountered was that very common encodings like x264 or x265 don’t work with the community edition and I can’t justify getting the pro version from an economic standpoint …
Supposedly a solution for Blender exists but I tried to make it work and failed :( https://www.cadsketcher.com/
If you don’t mind using text-based interaction you could give OpenSCAD a try … it’s like TinkerCAD (solids and holes) but with code …
I might be biased here because I’m a programmer by trade but I didn’t find it too hard … also mostly need boxy shapes … but still, I think it’s neat …
My personal top 3:
Video Editing - Kdenlive isn’t bad in and by itself but it seems really slow to work with, and getting any kind of smooth preview seems impossible even with proxy clips … the other day I bought a GoPro 3D camera, and I can cut, preview, rotate, reframe and encode with their Android app on my potato phone from 2021, and it feels snappy (I was surprised, really). Yet on my i7 laptop with Kdenlive, much simpler tasks feel much more sluggish on average …
CAD - I use OpenSCAD for 3D modeling and I love it, but sometimes a GUI-Based CAD program would be nice. I’m sure FreeCAD is powerful but the UI/UX aspect makes it hard to unlock that power. I’m a bit conflicted about it because I really don’t want to play down the efforts of the FreeCAD dev team, and it seems like everyone and their mothers talk badly about their UI/UX. But on the other hand I tried a couple times and got really frustrated, and I’m usually not one to shy away from steeper learning curves. Supposedly you can do CAD in Blender but I never really figured that out.
Laser cutting - While most slicers for 3D printers work on Linux, Lasercutting seems a different story. You can still use older versions of Lightburn but it’s not FLOSS and it seems strange to pay for a license if the support for your OS has been discontinued 2 versions ago (or one, not sure right now). I want to give Rayforge (https://rayforge.org/) a try soon but until then it’s LaserGRBL or the program that came with my laser cutter on a virtual machine.
Honorable mention: A linux phone would be nice.
Hmm not sure whether my cutter directly accepts SVG, I have to check … in fact I’m using Inkscape to assemble everything and then just use the application to generate gcode … not sure whether I can skip that step because the SVG doesn’t contain any info regarding cutting speed, laser power etc …
