    I have been using Assembly 3 for my personal projects as it resembles Solidworks' assembly. Thank you for supporting the open source community with your fantastic tutorials!

    The reason behind the inconsistent constrains blew my mind. No other tutorial mentions it either. I've been using Assembly3 with linkstage branch for quite a while now but never knew how to properly handle constrains. Thanks for the video!

    This is a great help to using the Assembly3 workbench. The coplanar error was as far as I got because I have projects that need to be delivered and didn't have the time to do a deep dive into Assembly3 and figuring out the error. So, you are actually adding value to our user experience and quality of work with your videos.
    And that's amazing!!!

    Thank you for your videos. Been using Freecad for light CAD work. The problem I see with it, besides the topo bug (which I think is a deal breaker for a lot of people, but hopefully fixed soon ), is the fact that Freecad wants to do too many things in one package, and everything looks like it is piecemealed together. For me at least, coming from Solidworks, a lot of things are sooooo... unintuitive. At my age learning something new gets harder everyday :)

      John , I was just sitting here thinking the same thing but couldn't put my finger on why ... yes, unintuitive,, an example, a slot in a cube .. I drew two cubes one inside the other .. boolean subtract, all looking good ..... one cube drawn in part design, the other in the part workbench .... all looking good until I wanted to do something else, I forget now, but realised I had drawn 2 separate models of whom communication was the last thing on their minds .... google, part design , sketch on face, groove , job done , elegant BUT ,,, and who would figure out to click on a dot ..I can't even see it ! ..... ON saying that freecad needs a good housekeeping, I remember its only maintained by a few really good fellas , quite literally a handful I think with others chipping in when they can ,,, so despite all that ,,, they have done a sterling job , and with videos like the above ,,, things are getting better .... I remember freecad .....15 ... shudder !

    Super helpful. Until now I've only been tipping my toes in FreeCAD, because I'm so used to Solidwork user interface, but there's no Solidworks on Linux to my knowledge and other alternatives like Fusion360 and OnShape are becoming less functional in their community versions. FreeCADs UI seems super clunky but the program seems to be pretty powerful and I can use it directly with KiCAD. Thank you for doing these tutorials, you're really good at explaining the functionality of this program in a concise manner

      If you don't like the UI of FreeCAD (like I did) take a look at the VertUI settings that change it quite dramatically. Search "VertUI FreeCAD Studio Petrikas" on UA-cam if you want a tutorial on installation.

      Check out the channel OficineRobotica. He shows how to customize the UI on RealThunder's branch, and how to download and apply presets if you prefer. You can change pretty much anything you want in the UI.

      unfortunatelly, Solidworks won't be available on Linux, because SW was written with a lot of VBA scripts, not even the Mono-framework could solve this problem. For me, the Linkstage 3 (version of RealThunder) was the perfect choice.

    Love this introduction to moving parts in Freecad. Well done. Question, was Assembly 4 not released at that time or do they not do the same thing ?

    • @JokoEngineeringhelp
      @JokoEngineeringhelp  2 роки тому

      I'm not brilliantly familiar with Assembly 4 yet; I know it has the same end goal but uses a different way of making geometry that bypasses topological naming errors than Assembly 3 does.

    I found the section using multiple bodies from one file interesting. I was wondering how the process would be different, if at all, if the multiple bodies are in a part container. This is how I use Freecad, I create multiple bodies that would logically be an assembly in a part container. I have multiple part containers for other sets of multiple bodies

    • @JokoEngineeringhelp
      @JokoEngineeringhelp  2 роки тому +1

      Good question. Part container use is very common in Assembly 3 and should not pose any problems. I meant to mention part containers in the video.

    Thanks, assembly 3 is really hard to use. Many constraints are either invalid or report errors. Can you come up with a basic usage guide? For assembly 3. Really useful for us beginners.

    • @tiborkemeny8644
      @tiborkemeny8644 2 роки тому +1

      not yet, because of the topology and connection issues. I've made some test with Freecad/Salome-Meca and Prepomax and it worked fine. The same stands for the meshing (e.g. having structured mesh works the same way - or with GMSH)

  • @thepragmatic6383

    It's the resurrection of Assembly3, a good compromise between Assembly2 and Assembly4.
    The question is whether Assembly3 can also automate movement like Assembly4 does?

    Do you have any thoughts on the differences between Assembly3 vs Assembly4 vs A2Plus?

    • @JokoEngineeringhelp
      @JokoEngineeringhelp  2 роки тому +2

      I have not used Assembly4 deep enough to really have a strong opinion yet, I would say A3 is best for assemblies that you plan on editing in the future in any way; I would go for A2 for an assembly to put together fast and simple without the need to edit in the future.

    What's that file selector at 9:41? The mouse cursor just vanishes, there's no key pressed shown on the key preview, and suddenly there's a file selector... How do you get that?

    • @JokoEngineeringhelp
      @JokoEngineeringhelp  Рік тому +1

      Good question, I'm not sure what I had to edit around there. If you're using linux, that's nautilus, if you're using windows, that's the regular file explorer, it's not connected to FreeCAD, it's just from files to drag and drop your parts in.

  • @donaldmccallum8453
    @donaldmccallum8453 Рік тому

    When I add bodies to parts to an assembly in A3 by dragging the parts all show up in the assembly and onscreen, unfortunately they are all "stuck" together and none of the movement tools will move them apart. Using V.20.1 with assembly 3 that I got from real thunder on a win 10 machine. What am I doing wrong?

    • @donaldmccallum8453
      @donaldmccallum8453 Рік тому +1

      I just found out what I've been doing wrong😅. I had the mouse navigation set to "OpenInventor" instead of "CAD"😯. At 14:41 in your tutorial you are explaining the DOF concept, but if your mouse is NOT in CAD mode you cannot move your part independently of all the all the other parts. Without this ability, it is all but impossible to set the constraints properly. By the way, I think, IMHO that you are producing an excellent quality video tutorial from the point of view of voice modulation and intelligibility, speed of your mouse on the screen (not too fast) and the all important content in terms of how well you seem to know the material but also in how well you convey this understanding to your audience. I am now looking forward to viewing all of your other tutorials. Fine work, Sir!

    None of this works on my FreeCad 20. You show selecting multiple items with CTRL key, this does nothing. If I click on add assembly it places it inside the part tree and can't drag anything into it. If I click on link button it shows a link in the tree but no parts in assembly. Downloaded the realtunder version and it is the same, in both looks and funtion.

  • @Sevalecan

    Sitting here being angry(Not at you). I'm not sure your advice on inconsistent constraints is applicable to me right now. I thought I misunderstood two similar constraints at first, and switching between the two (plane coincident vs plane alignment)... But no, inconsistent constraints, once it starts complaining, I delete the most recent constraint that caused it to whine and it doesn't go away (And trust me the only way I know it's the right one is because it only complains after I make it and solve and solving is fine before hand, and it seems the effing print function is throwing an exception)............ Sigh.
    Then if I close the file and reopen it (Of course saving it in this whiny broken state), it stops complaining until I add another logical constraint. FreeCAD Link is great, Assembly3 is driving me nuts(In my case it's a short putt, right?). I guess I'll have to dive into the code myself.

    FreeCAD is slow. No movement is good. Look at my videos and workbench. whenever you have continuous redrawing (recalculate) and many objects, FreeCAD will not work.
    This is the nature of the OCC and FreeCAD also.
    No way to fix that unfortunately.

    You just used the wrong constrain for planes. You should have used "Plane Alignment" and there are no errors. "Plane coincident" is used to center two planes. Basically 5 minutes of your videos is about your own error..
