Project overview

Learning SolidWorks through a complete mechanical system.

The objective was to learn how to model parts, create technical drawings and use SolidWorks across a complete engineering workflow. Instead of focusing on a single component, the project required a functional assembly with multiple frames, a tandem axle, a trailer body and a hydraulic tipping mechanism.

I modelled and assembled the project independently. The leaf springs, wheels and axle mounting components were sourced from an existing model. Every other component was either recreated from manufacturing documentation or designed by me.

My technical drawings

Manufacturing drawings I created.

I created these A3 manufacturing drawings from my SolidWorks models as part of the course project. The original PDFs show my dimensioning, tolerances, section views and component details.

Engineering process

The main challenge was integration.

01 / CHALLENGE

Managing a large assembly

The most difficult phase was bringing the frames, axle, trailer body and hydraulic cylinder together into one working SolidWorks assembly.

02 / SOLUTION

Systematic assembly work

I worked through component relationships and mate behaviour over several days. The size of the assembly also required careful management of performance and software stability.

03 / RESULT

A working mechanism

The completed assembly moves through its tipping range and connects the structural design, axle system and hydraulic mechanism into one model.

Assembly motion

What I learned

Skills developed during the project.

The project gave me practical experience in SolidWorks part modelling, multi-level assemblies and original mechanical design. I also learned to turn models into manufacturing documentation and exploded views.

Most importantly, I learned how small modelling and mate decisions affect an entire mechanical system. Solving the assembly problems required persistence, structured troubleshooting and repeated testing.

Complete documentation workflow.
The project progressed from part modelling and assembly integration to finished A3 manufacturing drawings and an exploded view.
