        SW Student Edition is $99/year for 2 licenses (two machines).

        Autodesk (autocad, Revit, etc) has one year FREE Student Edition for any legit "reg student" (can be one class at Jr College and lic is good for rest of year once you get the lic.)

      Very cool engine. I'll try to model it. Does the bore size change on account of the changing cylinder head angle? I'll try to design it such that it doesn't but still quite an interesting machine.

    I would recommend you go through this youtube channel and practice making everything he is trying to make.

    similar to Leetcode or whatever, look at the object he is trying to make and then try and make it yourself. if you cannot make it, THEN watch the video and practice the techniques he is showing you. UNDERSTAND each tool he is using and what it does.

    I'm dabbling in SW too, might help or all post questions.

    SW user forum seems all fricked up, use to be great.

    Last I heard their cloud powered 3D was all fricked up and I couldn't buy it for shit, wouldn't take my CCard or nothing and shitty reg process.

    They should hook up with Amazon and pay Bezos his 10% just to let people buy their shit.

      Solidworks essentially is for engineering. Is a high end CAD parametric modelling software. You can design very complex parts and machines, do fem analysis, etc,

        Can I send off the solidworks files into some printer and do 3d printing as well? sounds cool.

          yes, you export the files of your project into *.stl format and then with a software like cura you open that stl file and you can generate the code your 3d printer will need to make the part

            Cura has a SW plugin so you don't even need to save as .stl. Just click the button and it'll export to cura.

          Solidworks does that EXTREMELY well. With my Prusa printer and solidworks, i make items with consistent 0.010" accuracy. So far i've been blown away.

          Yes solidworks is one way to directly make blueprints (others are seimens NX, Catia, etc..). But with SOLIDWORKS you have to make the blueprints from 3D models unless you use some of the less sophisticated but 100% supported aspects of solidworks. If you do stuff like floorplans, then AUTOCAD is better since it's cheaper. You can do whatever you want with solidworks, but it's like $4,000. I do 80% machine design and 20% floor plan stuff and solidworks does it all great for me. But if you dont already know how to use 3D CAD, then i wouldnt use it for 2D floorplan stuff. That would be like requiring someone get an F1 racing licence just so they can drive on regular city roads.

    I need to model a 2D hole for a part to be inserted it. The tool can only do straight lines, not curved, so my plan is to cut the hole like the red octagon.
    How do I calculate the lengths of the top and bottom parts? Hardmode: tell me without calling me stupid

      no math required. You could probably use pythagorean theorem if you make the diagonals into triangles if you want

        I don't understand. where did you get 1/3rds from?
        The worst part about this is I don't have a way to print things to scale, otherwise I'd just print some paper with different guesses and cut them out and test fit them.
        Now I'm leaning toward a plain 11.5 x 12.6 rectangle even if it leaves corners showing because this shit is too hard to figure out

          1/3 doesn't even matter. Just determine how long you want the top and bottom cut to be. 1/3 just seems elegant and even

            thanks, this helps a lot
            now I have to enter it into xy coordinates

            You would have to define the angles first, so right now it's impossible to answer.

            it's more of an engineering problem than a math theory question. the hole has to be big enough to fit (with some slop) but not to big to show under the nut when the jack is mounted.

            https://i.imgur.com/W4BFEwZ.jpg

            Draw circle with center "c" using the radius of 6.3mm for the hole you want to cut out. Bound that circle in an octagon with center "c" and by definition this will have all eight sides tangential to the circle. Draw a rectangle centered at "c" with height equal to 2*r and width equal to 11.5mm. Now cut out / subtract all shapes outside of the rectangle, and with the remainder, cut out / subtract the shapes outside the truncated octagon. This should leave you your squished octagon shape you have in the red outline if your image. Sorry I can't draw a pic, I'm shitposting from a phone. Good luck anon, you got this. Post results.

            this sounds like how I'd do it in inkscape

        if you know your dimensions then you know the angle

        however you don't describe the dimensions fully enough
        what is the length of the straight side and the height of the curved side? without that you can't know the angle

        the angle is visible in their picture, why can't you measure it?

        you know the height top to bottom but you need the straight edge length to know the angle if that makes sense
        just imagine you could drag the vertex down and have a shallower angle or move it up and have a steeper one but obviously if you dragged it too far down then you'd cut into the straight part

      There's a huge learning curve, lots of buttons and settings, and it truly sucks balls with enterprise-type work. Otherwise it can do anything you throw at it. Surfacing, boolean, 3D sweeps, name it. It's good for small to medium assemblies and part design.

    Can you tell me how they model stuff for castibg/injection molding?

    I was trying to model an existibg motor housing and modelling the draft angle was ver hard.
    Is it sometimes done so that the model is just made with vertical faces and a draft angle is added at the very last step by sone specific software?

      >Is it sometimes done so that the model is just made with vertical faces and a draft angle is added at the very last step by sone specific software?
      model the part as-is, then make a new body or part for the drafted geometry using (3d) sketch references to the original

        he's a lying gay or an idiot. anyone with large assembly experience in SOLIDWORKS would tell you that workstation specs are less important than how you set up Virtual Assemblies and all the tricks you can do to make parts not load and just be basically images of a real part. I've done 10k unique part machines before on a toaster. It's not easy though. You need to be good.

            well for one autoCAD is crap that hasn't kept up with improvements to CPU/GPU design in like, two decades.

            The other thing is literally what he said. Just like a videogame you want as little stored, calculated, and rendered as possible, at any given time. The tools are there, most people just don't learn them in their cad or CS 101 classes.

    I've been wanting to get into robotics, and I was thinking about a hexapod inspired by the dwarven spiders from morrowind. See this very shit sketch for example.
    I want to make a sphere in 3 parts, top, middle and bottom, and make it so that the top and bottom layers can turn clockwise / counterclockwise independently.
    The bottom sphere also has gear toothing and acts as a big gear, letting the whole construct angle itself.

    Trying to construct it but I'm a mechanics / CAD brainlet. This is the inspiration:
