Hello, let me introduce myself, my name is EL DIK Ahmad. I am a second-year student of mechanical engineering at the HEIG-VD University. My academic background is as follows: I finished my first year at EPFL and I completed almost all the courses in my second year as well. However, in my second year at EPFL, I had to retake a course that I had failed the previous year. Unfortunately, with the arrival of the COVID-19 pandemic and for personal family reasons, I had to leave Switzerland and return to my home country of Lebanon, where I spent a year. When I returned to EPFL and explained my situation, I was informed that I had no reason not to take the exam (not to show up for the exam), which led to my expulsion from the school.
I then joined the HEIG-VD to continue my studies, directly in the second year. However, a problem arose: HEIG-VD automatically validated CAO1 and CAO2, whereas in my first year at EPFL I studied CATIA instead of SolidWorks and we barely completed a small project, without a design or anything similar. So I find myself honestly lost in the 3-4 CAD courses and don't know how to follow the courses, because there are no explanations, only a complicated semester project, and the teacher doesn't have time to explain everything to me.
That's why I found this group on the Visiativ page, made up of engineers and talented people. I hope someone has a few hours a week to dedicate to me as an assistant, and of course I'm willing to pay for this work! We can discuss the financial terms together without any problem.

I live in Lausanne, but I can make trips to your place too, anywhere in the canton of Vaud!
Hello @ahmad_el_dik I think you've come to the right place Welcome to the myCAD community! I'll let the members of the community answer you; If you don't have any feedback, don't hesitate to contact me to see together how we can help you! Coralie
Did you start by doing all the tutorials delivered with Solidworks? This is already the minimum to acquire to start with and it is very detailed:
Then if that's not enough for you, there are also a lot of Youtube tutorials in French and finally afterwards you could consider a catch-up with a teacher (if teacher nearby)
Hello, thank you for your answer! I have watched a lot of youtube videos and I manage to create qlq small assemblies, but I also need help in the design of my project, and it is much more complex than the tutorials given to solidworks, that's why I need someone with experience. (I also have 10 other subjects to follow this semester so the time to discover tutorials is a problem too)
Not sure that someone from your region, outside of their working hours, has free time in common with you. Here on the forum it is mainly professionals in the trade, and they all also have other things to do in the evening or weekend. On the other hand, if your topic is clear that you know what you want to do but you can't apply it in CAD on SW, on this forum you will find the necessary help. If, on the other hand, you are looking for someone to do your study + CAD project for you for a fee, not sure that you are in the right place. Students who make this kind of request land every year on this forum. some with good attention and others not. So expose your subject if you wish and then we will advise. And maybe if your subject is clear and precise, someone in your region will be able to devote time to you in addition to the help provided here. To sum up, what are your specifications and your idea to get there (sketch, or beginning of CAD...)
I'm not looking for someone who does the project for me, I'm looking for someone who knows what needs to be done, and next to me, explain to me how to think and how to do it, and that I work in front of him, and tell me when I make mistakes (a teacher). My projects are: -a project that my class has already done last semester (cycloidal reducer), but I want to do it again with someone to learn.
The project I have now (I have 8 weeks to submit it): the specifications are: a system for packaging chocolates, like this video: https://www.youtube.com/watch?v=yg8qILTuiFw&ab_channel=SAPAL , but we have to do just the part where the chocolate is introduced into the rotating wheel, the chocola held by the tongs, but that the rotating wheel must always have a constant speed, So the part that injects the chocolates into the spinning wheel must have the same linear speed as the wheel, then quickly return to that place to inject the next chocolate!
In this case, the forum is there for you. My advice Move forward with your project and when you have the slightest question we will be there to help you.
They don't joke about the projects in your school. I would have been in PLS at the time I think, without knowing where to start!
Have you started to transcribe all this under specifications? And get the most important points out of it?
Have you made a schematic diagram / small sketch of what you want to do in the end?
Do you know the overall dimensions / the space that has allocated you in the special machine?
If so, all you have to do is draw little by little in Solidworks so that it takes shape. And then you will start to encounter " concrete " difficulties where we can help you
Hello! We got the (specifications yesterday), so I haven't had time to make any drawings/calculations yet, but I'm going to start this weekend!
Concerning the specifications (the teacher wanted to be like a customer who asks for a chocolate packaging machine): the only thing he specified is:
we must make a wheel with a diameter of almost 500 mm that rotates at a constant speed of almost 900 rpm, it contains 6 clamps: the part that must be carried out is the injection of the piece of chocolate into the wheel that rotates (in the clamps), but the problem is that the wheel rotates at canstant speed, So we have to make an injection system that follows the rotation speed of the wheel during the injection, and then comes back to that place to inject a new part with the new clamp. If you watch the video where I posted the link on the forum, at minute 0:33 it's similar to this system but in the video the wheel that turns stops for a few milliseconds to inject the chocolate-paper into the wheel and then restarts (stops for each step of packaging too), in our case everything must be at constant speed. (the chocolate injection system is linked to the same motor that turns the wheel, so we have to make a cam system to make it work)
Thank you everyone for your messages and support on my post here, I am really happy to see a lot of answers and support regarding future questions from me. I hope and think it will go well even if it's my first CAD project!
The first thing to do or to give us is the specifications. Because I see before I even start an inconsistency and also missing information.
1°) Incoherence = 900 rpm, i.e. if I still know how to calculate 900/60 s = 15 rpm / second, which means that each wrapping operation (which includes several stages) must be done in this space of time.
2°) Missing information a) Size of the chocolates (are they bites, mini bars) choice of packaging (papillotte, (b) the nature of the single-layer or double-layer packaging with two different materials). c) Do you also have to put everything out in a bag or a tablet at the exit.
it also seemed to me that 900 rpm is huge but that's what the professor wants. (you can put a protection around the clamps just after the injection until the sotie)
@ahmad_el_dik , it's not we can put protection, it's we have to put protection. Always think that the user can be carried away... especially at this speed^^
The size of the chocolates are 25 mm in diameter, shape: half sphere (as shown in the youtube video I put before), concerning the wrapping operation itself, we are not concerned in this project, it's just the wheel system with clamps that rotate 900 rpm, and the system that transmits the chocolates that arrive by a conveyor to the clamps and biensure this system must have the same linear speed with the impeller so that injection is possible. The impeller and the injection system are both driven by a single motor. at the exit the chocolates slide on a container,
P.S.: sorry everyone if I have a lot of spelling mistakes, I am not a native French speaker. <3
