I’m looking for some advice from people who work as mechanical designers/engineers, especially those who have made a similar transition.
After high school, I went directly into working instead of going to university. I now have around 5 years of experience as a Technical Designer in Italy, where I designed metallic building structures from scratch using SolidWorks.
I also worked with PDM/PLM systems and was responsible for things like 3D modelling, assemblies, drawings, BOMs, production documentation, and solving technical problems.
Since I didn’t go to university, I always felt that I had to work harder to teach myself as much as possible. I learned a lot through experience rather than through formal education.
Eventually, I moved to Stockholm, Sweden. I quickly discovered that finding a CAD/Mechanical Design job without a university degree and without being fluent in Swedish was very difficult.
So I made a plan
I decided to move into CNC/CAM programming and manufacturing. I thought it would be a good way to strengthen my understanding of how parts are actually manufactured.
For the last 2.5 years, I’ve been working with CNC milling and CAM programming, mainly using Fusion 360.
Honestly, I’ve learned an incredible amount during this time. CNC taught me a completely different side of mechanics and manufacturing.
I’ve learned about machining strategies, tooling, workholding, feeds and speeds, material behaviour, tolerances, and what actually makes a part manufacturable.
I currently make fairly complex aluminium parts, including 5083/6082, with very tight tolerances. I’ve become one of the more trusted people in the company for difficult parts and manufacturing problems.
However, I’ve realised that the workshop environment isn’t where I want to stay long-term.
So I decided to move forward and have accepted a position as a Mechanical Designer.
And this is where my concern starts.
I know I have a lot of useful experience, but I also know there are things I don't know yet.
For example, I understand GD&T concepts and the symbols, but I haven't had much practical experience applying GD&T to mechanical drawings. I don't always know why a particular tolerance should be 0.05, 0.1, 0.2, etc., or when something should have perpendicularity, position, flatness, profile, etc.
I'm hoping to learn these things properly in the new company.
My biggest concern is the first 6 months. I really want to prove that I’m good enough and pass the probation period.
I’m not expecting to know everything from day one. I’m prepared to ask questions, learn from the engineers around me, study in my free time and put in the work.
But I’m wondering:
For people who work as mechanical designers, does my background sound like a reasonable foundation for the role?
How much would you expect a new mechanical designer to know independently when starting?
And especially for those who moved from manufacturing/CNC into mechanical design:
What were the biggest things you had to learn when making the transition?
I’d really appreciate honest opinions even if there are things you think I should work on before starting.
Thank you
