  • 3D design software startup

    Extraordinary topic. I want to "feel the pulse" of the public, or to see what the public's mood would be regarding what I am going to present here.
    Since August 2018, when I bought a 3D printer, I realized that the whole story will be meaningless to me if, in addition, I don't learn to draw
    in 3D, at least minimally, even if only for my needs.
    I'm only interested in 3D printing and 3D drawing enough to be able to draw and print various housings, boxes, parts, etc. myself.
    Everything I need for metal detectors and similar devices. Generally for the electronics I deal with.
    There is a lot of good software on the market for these purposes. I got the impression that Autodesk is a leading company in this business.
    I have tried all their products. But also the products of some other companies. Software for 3D design.
    The problem with 99.99% of that software is that it's a huge complex software package that includes way more than what I need.
    At the same time, it is very complex to learn. And I needed something quick, right now, so that without too much work and brainstorming,
    I could make a model and print it immediately.
    Anyone who has already mastered such software well; will laugh at all this.
    He will not need anything further. Because he devoted a lot of time and effort and mastered some complex software, and there is everything he needs.
    But... from 2018 until now, I've seen many cases like mine on the net, countless people don't want to bother learning bulky and expensive software
    that has to be constantly renewed and constantly paid for.
    And such bulky packages are always asking for some additions to this and that... the whole system is oriented in such a way that it allows the user
    to finish the job, but he has to constantly do something extra and constantly pay something extra.
    You know the story, I don't need to spend too much time and space here to explain it to you. So a huge number of people on the net want the same
    thing as me; simple, easy, fast and not very expensive, offline above all.
    I have found Tinkercad to be a phenomenal software that completes all my needs. And with it I have done about a hundred works so far.
    Some simple and some very complex.
    Although at first glance Tinkercad looks like a simple platform for children to learn and take the first steps in 3D design... this software is much more than that.
    And not only me, I see that many have decided on that software and are very satisfied.
    But... EVERYONE wanted an offline version of that software. Online has many disadvantages.
    On some Autodesk portal, many have publicly asked Autodesk to provide them with an offline version.
    They received a clear answer that it will not happen and that it is not planned.
    Then I realized that we are all doomed to the will of Autodesk.
    They can give us Tinkercad to use for free for a long time... and they may one day decide to discontinue it or start charging.
    There are a couple of other major flaws; if the net is overloaded and the bandwidth and QOS drop, the use of Tinkercad is difficult and sometimes impossible.
    And right at that moment you may need to do something urgent.
    Other; if you work for a long time on a 3D work, you make something very complex... it's not just yours, it's on their server, and who can guarantee
    that they don't collect good works for nothing?
    That's why I've been thinking for years about what it would be like to write such software for my own needs.
    And now I come to the point.
    I'm an "average" programmer but I've gotten to know 3D drawing and Tinkercad very well.
    And my younger son is a top programmer. So this winter we started working on such a software.
    These days we are putting together the "zero" version. We are just at the beginning.
    According to my estimates, the first complete version will be ready in the spring or summer of this year.
    A lot of work and a lot of time will be invested there. Very expensive work otherwise.
    And now I'm thinking, how can we commercialize that great work later?
    Not in the same way that Autodesk did it (because I just criticized that way), but in a more "humane" way.
    For the software to be offline, but at a cost.
    The price should be affordable for the average user. And yet enough to repay the invested work, knowledge and time.
    Of course, there is always piracy. Whatever protection I put on the software; sooner or later a hacker will be found who will easily break through and "crack" it.
    We need to figure out a way to "buy time", to earn enough money to pay for so much work and in such a short period of time, before the hackers had time to create a pirated version.
    I have more ideas in mind about it. I will apply some of it. But I am interested in the opinion of the public; would there be more interest in such software?
    Already; The "zero" version records in STL format. And Cura (a popular slicer) easily accepts such files for further preparation.
    Opinions? Suggestions? Experiences? Ideas?

    FreeCAD is open-source with core functionality written in C++, and interface coded in Python.
    It's free, and runs on Windows, MAC, and Linux. It can export to many formats such as STEP, IGES, OBJ, STL, DWG, DXF, SVG, SHP, DAE, IFC or OFF, NASTRAN, VRML, OpenSCAD OSG, etc.
    With such serious competition (and did I mention that it's free, and can be used offline?) you really have a difficult task ahead.

      I have known about FreeCad for a long time, probably since it appeared.
      And I remember the versions with fewer options and more bugs... until today when there are many more options and I'm not sure if there are any more bugs at all (good job done there).
      But... have you ever tried to draw something in Tinkercad? And then repeat the same in FreeCad?

      My point is; drawing in Tinkercad is so easy, elegant, good, smooth... a very complex object drawn in half an hour to 45 minutes.
      And drawing in FreeCad is painful, difficult, time-consuming, not smooth, with many bugs that show up along the way... real torture.

        The software my son and I write will be 100% based on Tinkercad.
        Nothing from Tinkercad will be copied in terms of copyright infringement, of course.
        But the feeling of working in that software will be the same (and I hope in some segments even better) as with Tinkercad.
        The point is on the ease of work, that everything remains very simple, easy and without obstacles.
        Who worked in Tinkercad; he will understand what I mean.

          Thinkercad is my favorite when i have to design something for my 3D printer. I tried other software but didn’t like.. what i would love as an improvement is better positioning of pieces one on top of each other in terms of measuring (i cannot explain, hard to do it, xy positioning relative to the piece. “Z” axle is eazy) and the possibility of making “bevel” to the final model. This is what i remember for now.. i did not had the time to use my printer in a while. Good-luck with your project!

            Thanks! I Agree with you. Tinekrcad is splendid for those who don't have time to sink into dubious study of "how to, this and that" and yet to finish the job asap. Tinkercad offers exactly that; simplicity but with superb output.
            I spend some time with Autodesk "dubious" packages, also with Blender, few others... I noticed; I am not getting any younger doing that...
            A long and hard work is waiting me and son on this. This is not trivial task. I know that in advance.
            Yet... at the end I will have sort of offline "Tinkercad". Hopefully.

              When I was much younger I got the urge to write my own Spice simulator and plotting graphics. This was long before we had LT-Spice, there was just PSpice and VAX-based Berkeley Spice, and I had DOS and Turbo-C to work with. As I dug into the math required to solve huge sparse arrays I quickly learned this ain't a task for an individual, and I eventually gave in to reality. A graphical CAD program sounds even worse, but I suppose the software tools and algorithms are way better today.

                Ah good old times!
                Today is easier, trust me.
                Yet, software will not auto write by itself, still lot of work.

                I think you misjudged; spice seems to me much more difficult to write.
                Although, I wouldn't know, I've never tried.
                "3D CAD" is too heavy a word.
                Because AutoCad, Fusion, Maya... and Tinkercad can be found under the same term!
                And differecnes are so HUGE!

                    Freecad has been good for me since the 0.2 release ... there are some bugs .. but alot fixed.
                    I used to use ( and pay ) for Fusion 360 ( and it had bugs too and was so sloooooooooow )... Freecad leaves it in the dust now for coil housings etc.

                      Fusion 360 needs powerfull machine with powerfull graphic card. Maybe that's why it shows some bugs.
                      I7 3. genetation and I3 10. generation based machines, the second one with Radeon (400 euros) card. Fusion 360 works flawless.
                      It is resource hog.
                      But I am not using it because it is much faster and simpler to me to use Tinkercad.

                          Hello.
                          I agree that having all my designs on a disk somewhere is something annoying.
                          But at the moment I use Fusion 360, which is free for "makers". (non commercial use). It is limited to 10 design open at the some time. But it is not limitating in fact.
                          It is quite easy to learn. (much more than Solidworks for example)
                          And it is possible to work offline , not connected during many days.

                          ​​But for 3D, a good graphics card is required. Not a player graphics card. A real 3D certified graphics card. Not so expensive if it is a second hand.​

                            Some devil makes me do stupid things now and then.
                            The other day I "discovered" some old game archives.
                            "Brothers in arms" CD image packed in archive.
                            Yup!
                            And I start the installation, it ends seemingly without any problems... it asks to restart the system... and voila!
                            My system on the SSD drive is messed up!
                            And I had a very nice Win7 on that disk.
                            Ok... time to accept my fate and finally give up on Win7.
                            Because there are more and more problems with it.
                            Except there is no more support; it doesn't even have security patches and is becoming an easier target for viruses, trojans, etc.
                            So now I've finally and definitely switched to Win10.
                            A difficult decision for me.
                            And while I was rummaging through the archives; I come across Autodesk 123D !!! Wow!
                            Easy to install, works without problems. Even now, from this time distance, it doesn't seem so difficult to me.
                            I have it in the system, when I have time I will deal with it a bit more.
                            But it will still not affect the development of own software.
                            Because it is a great challenge and great satisfaction when it is done.

                              Hı All,
                              Can you attach the 3d stl file of the Bulgarian universal metal detector device box?
                              It can be in large image files such as tesero or garret, minelab.

                              Kind regards
                              Gürdal
