  • FreeCAD 1.1 is out

    Jump

  • I used SW professionally for years before I retired and SW was suddenly not free to use for me anymore. Personally, I found the switch to FreeCAD was pretty easy for me. But the ease or struggle to learn something new varies a lot between people.

    Best I can tell you is to forget everything you "know" from SW as best you can. And when you get frustrated that what you are doing in FreeCAD doesn't work like SW, try to remember we ain't in Kansas anymore Toto. That's how I had to approach things.

    Good Luck! I'm pullin' for ya!

  • I've been using it since it was a weekly release, (now I mostly use the 1.2 weeklies), and it's been very stable even on a low powered mini desktop with 8 Gbits of shared RAM. I think they are finally finishing up the timeline that was set out when they went after the TNP mitigation and general cleanup of the disaster that was .1X series of FreeCAD with the 1.0 release.

    Spoiler Alert: I think the 1.2 Weekly releases are even better yet. So give that a shot if you are willing to put up with occasional breakage and problems. The more users of different skills with different hardware can really help speed the killing of bugs if you report issues. Besides, it's just plain fun!

  • Keep trying and keep practicing. Install FreeCAD and practice with MangoJelly tutorials to learn.

    One thing that often makes it hard for people switching to any new CAD is things don't work the same way. So do your best to forget the way you used to do things. Fusion isn't FreeCAD and FreeCAD isn't Fusion. You will need to learn new things. So don't expect it to work the same way.

    The next thing that is very helpful is to find models to practice and gain confidence and skills. MangoJelly tutorials are great to learn from, but you need varied practice to gain skills. Here are 50 models you can practice with to gain confidence and skills using any CAD program. Other practice models can be found if you do some searching.

    Good Luck!

  • It's ok to not get it when it comes to parametric CAD. I can't get the hang of OpenSCAD. And don't get me started on Blender. Years of trying, and I STILL can't make that doughnut......

  • I have used Fusion and can get what I want from it. But I have an intense dislike of the clown car UI.

    So sit down and watch MangoJelly's tutorials and practice them. Enjoy that smooth Aussie voice. It takes time to learn new things so don't give up. We're pulling for you!

  • It's pretty simple don't watch it then. No one, least of all me, is going to force you to watch it.

  • The FCC decided that all foreign-made consumer-grade Internet routers are prohibited from receiving FCC authorization and are therefore prohibited from being imported for use or sale in the US.

  • A nice thought. But the Great Unwashed Masses do not care. They want a Quick Start Guide that just says "Plug it in" and no other steps required. They want the black box because they don't want to learn and understand.

    And that attitude is less about the oligarchy and a lot more about all lazy people.

  • They all lobby the regulatory agencies for the same things. Tesla ain't special there. Every auto manufacturer has formulas that they use to determine how many deaths cost them more than doing nothing does.

  • I won't argue with you over that. As an old retired medic, there are a great number of ways to die that are horrifying. And I've seen some of them.

  • In the western world, deaths from bananas to cyber trucks to rocket ships are tracked. And believe it or not for many of those things there is a threshold of deaths per month or year that is required before any safety concerns are invoked.

    They have charts with actual numbers to decide on how many people need to get hurt before a stop sign at a street intersection gets installed. And how many deaths need to occur before those stop signs are upgraded to stop lights.

    While I don't own a cyber truck or anything Tesla and never will. 5 deaths out of however many miles driven by the over 1/2 million cyber trucks that have been sold, is barely statistical noise.

    *****Annual deaths from bananas is statistically insignificant. But strangely PubMed did have a German paper about a woman that evidently committed suicide by eating a very large number of bananas. Hyperkalemia is a real thing and there are people at high risk of it. But man, kidney failure is a very painful way to choose to die.

  • Working outside

    Jump

  • I spent all my childhood life growing up on a dairy farm. Worked from home, got to do various types of exciting manual labor and operate somewhat dangerous machinery, AND I got to work outside no matter the weather.

    So suck on that California. You ain't that special.

  • Even rifling can be cut with nothing more than a hardened piece of tool steel, a green sapling and a bit of time and patience to make what's called 'Scratch rifling'. Even a wooden rifling machine isn't hard to make if you want to boost production a bit.

    And yes, the metal working shop I own is perfectly capable of making every piece of any firearm you might want. I have even made a black powder 2" Coehorn mortar to launch baby food jars filled with concrete 100s of yards. I know guys who have made full sized and functioning Gatling guns down to the horse-drawn trail it was mounted to. An expensive and time-consuming endeavor.

    But it makes the general populace feel good and gives politicians more power.

  • 3D printing in an unheated workshop

  • Immediately, there should be little issues. The woodworking dust being the worst, it's insidious.

    Long term, you will shorten the life of your printer some as all the components go from cold to hot. Will it be horribly noticeable? Possibly. I need to keep my machine shop at least at 50F/10C to keep the electronics functional and rust at bay over the long term.

    Jump

  • Firstly, never take legal advice from youtube or even here. And it's very unlikely you would ever be caught doing it as long as you don't sell the parts. Nor should you ever reverse engineer life threat level parts. Because you ain't that smart or good. And if you are that smart, you know better than to do so.

  • If you are reverse engineering something like those used sleds, it's unlikely you are going to have any kind of paper to give you those critical dimensions. As he said, those sleds were bought second hand. You ain't ever going to get any kind of manual with them.

    As far as measuring goes, It's all G20/G21. I'm pretty sure the overwhelming vast majority of 3D printing people own a 6"/150mm digital caliper. Metric or US Customary numbers are available at a mere push of a button. And you should also own a 6"/150mm stainless steel scale. Evem Mitutoyo are less than $20. Though I prefer Shinwa brand myself because I find them easier to read with my old feeble eyes. Buy one or several. But to be honest, just about everything in the US these days is metric. We just don't brag about it.

    Those are the 2 basic tools you need at your desk when you are reverse engineering a part or design something the new the world has never seen. Add a pencil and a sketch pad and you are set.
