  • You didn’t select “Create Symmetry Constraints”. I’m not sure if it will solve the issue completely, but it will probably make some difference.

    One thing I see that may come back to bite you later: You can create sketches that make multiple bodies when padded, but I’m not sure why you would want to with the example in this video. If the sketch is two identical bodies mirrored across an X/Y/Z plane use the part design mirror feature and offset the sketch’s attachment not the geometry in the sketch. It works better for that and keeps your sketches simpler, and you get to use symmetry for one side of the two things you are making because the origin will be in the center of one of the objects.

    Sketches where the origin of the sketch isn’t the approximate center of a single closed wire are annoying later if you want to reference them in other features or sketches.

    Are you making sunglasses? 😎




  • which also makes copies of the constraints which are completely independent from the original constraints on the left-hand side - delete the stupid new right-hand side constraints and slowly, painfully constrain the right-hand side copies to the original left-hand side elements

    I feel like this is not how it works for me. It does copy the constraints and automatically create symmetry between any points across the selected center line, but if you’re making a mirror why is that not what you want?

    Also I’m unsure about the behavior in older versions of freecad, the constraint behavior of this feature is new in 1.0


  • You want Sketcher Symmetry but it’s not quite what other CAD packages have. Select what you want to mirror, which is probably the entire sketch using the drag selection box, select the Sketcher Symmetry tool, then press J to add constraints.

    It’s not perfect, I suspect because it can’t read your mind as well as the big CAD packages about where you want coincident constraints for joining lines, but it’s mostly OK.

    EDIT: I can’t tell if you are describing the Sketcher Symmetry tool in your 4th paragraph or not. You will sometimes get over constraints where the end points intersect but you can delete them with one click and make those points coincident instead. I suppose this could be time consuming if you have a really really complicated sketch with multiple intersecting points, but that probably wouldn’t pad anyway.





  • the qobuz webapp is hi-res too, I just use it in Firefox and my dac reports the same bit/sample rate that qobuz does. AFAIK there’s no compression there though I haven’t extensively verified that, only that the end result is 24bit/192kHz if that’s what qobuz says is playing.

    EDIT: Also, qobuz is nice because there’s very few things you can click on in the web interface which cause the music to stop playing. I really appreciate that feature… looking at you bandcamp…



  • Are your games all wine/proton games? For me in sway they all have the same class followed by some uid thing:

    ] > swaymsg -t get_tree
    [...]
      #92: output "DP-5"
        #70: workspace "21"
          #126: con "Automobilista 2" (xwayland, pid: 171976, instance: "steam_app_1066890", class: "steam_app_1066890", X11 window: 0x5400001)
    

    Or gamescope:

    ] > swaymsg -t get_tree
    [...]
      #92: output "DP-5"
        #70: workspace "21"
          #124: con "Assetto Corsa" (xdg_shell, pid: 170694, app_id: "gamescope")
    

    EDIT: Also allow_tearing was added to master 3 weeks ago, so this is definitely not in the current release. FYI to anyone who might try it.





  • This gave me an idea. Have you considered buying a used higher quality rack and modifying it? Might save some time and get you what you want with less new material, and sort out some of the harder parts to fabricate because they’d be done already, possibly only requiring a little bending to align with your eyelets. Plus you’d be saving something from someone else’s scrap pile.

    Around me there are a few community run used bike part shops. They typically have lots of racks and other parts kindof organized into piles or boxes by type. I can usually find something close to what I need if it’s not too specific.


  • I’m not aware of a welding process that is safe for humans without at least a dust/fume extractor. That and a respirator with the appropriate filters for the application that fits under a welding hood is basically standard equipment even for hobby welding in my opinion. Also hex chrome is a particulate, not a gas, and tig welding uses solid rods (not flux core) and a much smaller heat affected zone so it’s already better in that area AFAICT, but I’m not an expert in this area.

    As far as particulates when welding go you should watch how careless people are when they grind their tungsten electrodes containing all kinds of dangerous additives with their respirator around their neck because “I’m not welding so I don’t need it”.

    So yes, this is good advice. We should all think more about the things we do, even when working on home improvement projects and mundane stuff, that could end up damaging our lungs.
