Mechanical Design is a discipline of engineering that focuses on applying a combination of physical principles, mathematics, and materials science on the design, assembly, and maintenance of mechanical systems. The area often encompasses the development and analysis of both individual components and complete systems ranging from an entire car engine to smaller parts such as gears, levers, bearings, springs, hinges and other small mechanical parts. Mechanical Engineers use the knowledge and skills acquired to research, design, develop and test machines, engines and other types of tools for different industries. In essence, Mechanical Engineers create solutions that keep people and processes safe.

I have a set of detailed specifications for a series of aluminium-and-glass windows and doors and need them brought to life inside StarFront. All profiles, hardware choices and performance criteria are already defined; what I am missing is someone comfortable enough with the software to translate those specs into accurate StarFront projects that my production team can pick up without a hitch. Your job is to set up each unit, verify dimensions, assign the correct profiles and accessories, and make sure all parameter calculations run cleanly. Once everything balances, export the fabrication drawings, glass sizes, and cut lists straight from StarFront so I can hand them to the workshop. I will supply the spec sheets and any catalog data you may need at the start. Please let me know your exp...

I’m developing a new mechanical component and need precise 3D models created directly in AutoCAD. The work is strictly mechanical design—no electrical or civil cross-overs—so familiarity with standard mechanical tolerances, fits, and industry drawing conventions is essential. My priority is an accurate, parametric 3D model that I can update as dimensions evolve. If you normally build in SolidWorks or CATIA, that’s fine as long as the final files land in AutoCAD format without loss of fidelity; native .dwg is my preferred end point. Deliverables • Fully editable AutoCAD 3D model of the part/assembly • Exported STEP or IGES file for downstream simulation • A short drawing pack (PDF) showing critical dimensions and exploded view I’ll share...

The scope covers three systems: water supply, drainage, and gas piping. I already have the architectural and structural backgrounds in DWG; what I need from you is a fully coordinated plumbing layout that can go straight to our installers and the approving engineer without additional mark-ups. Depth of detail is important here. Line sizes, slopes, pipe materials, fixture connection points, valve locations, clean-outs, vent routing, isolation details—the whole lot must be called out and keyed to recognised symbols. Wherever manufacturer data is needed (e.g., backflow preventers or pressure-reducing valves), reference the exact model numbers so ...

If not, there is no need (we will screen out candidates who are not a fit, you will just be using up your and our time). We have a need to evaluate smallest-possible VCM (or other actuators) fo...
I’m looking for a mechanical designer who can take my concept for a CNC-machining production machine and turn it into a fully detailed design package. The end goal is a robust machine that will streamline manufacturing on our shop floor, so every decision—from frame geometry to drive selection—needs to prioritize rigidity, repeatability, and ease of maintenance. Here’s what I need from you: • 3D CAD models of the entire machine, including all motion components, guards, and service access points • Manufacturing-ready drawings (assemblies and individual parts) with tolerances and surface-finish notes suitable for CNC fabrication • A concise bill of materials that lists off-the-shelf parts alongside any custom components • Brief design ration...
I need a mechanical engineer who can take me from a rough idea to a fully documented, production-ready CNC machine. The emphasis is on manufacturing: the goal is to create a robust, accurate machine that will sit on my shop floor and turn raw stock into finished parts day in, day out. I am not looking for maintenance advice or just a new post-processor—I need the machine itself engineered. Here is what I expect: • Complete mechanical design in 3D CAD (SolidWorks, Inventor, or Fusion 360) including frame, linear motion components, spindle selection, drive system, guards and enclosure. • Detailed 2D drawings and an itemised BOM with off-the-shelf part numbers and suggested suppliers. • Strength, vibration and thermal checks to be sure the design will hold tolerance...
