I already have the complete 4 m × 10 m civil tank layout in AutoCAD 2D; what I now need is a faithful 3-D reproduction that mirrors every line of the original file. The model must be detailed enough for direct use as a construction or manufacturing reference, so accuracy on dimensions, wall thicknesses and nozzle positions is critical. Inside the tank, please include all specified internals: piping runs, valves and the required support structures. These elements should be modelled as individual, editable solids so they can be isolated for fabrication drawings later on. Deliver the finished work in an editable AutoCAD-compatible 3D format (.dwg or .dxf) along with a set of locked view exports (PDF or PNG) that clearly show plan, elevation and at least one isometric perspective. If y...

Job Title Mechanical / Product Designer – 3D Printed Electronics Enclosure Project Overview We are seeking an experienced mechanical / product designer to design a functional, production ready enclosure for an electronic device. The initial build will be 3D printed (FDM/SLA), with a possible later transition to CNC or injection molding, so strong design for manufacturing (DFM) fundamentals are required. This is a contract / project based role with potential for follow on work. ________________________________________ Scope of Work • Design a custom enclosure optimized for 3D printing • Develop internal mounting features (2.2 REFORM screws with BOSS) • Design external features (I/O component case cutouts) • Ensure proper wall thickness, tolerances, clearances, and ...
Project Overview We are developing a compact cylindrical chamber where fluid enters tangentially to create a strong vortex flow. The chamber currently produces rotational circulation, but we want to enhance the swirl strength and stability. The goal of this project is to design internal helical guide ribs (swirl-inducing surfaces) along the inner wall of the chamber to improve fluid circulation and increase angular momentum in the vortex core. We are seeking an engineer with experience in fluid mechanics and mechanical design to optimize the internal rib geometry. System Description Chamber type: cylindrical vortex chamber Internal diameter: ~150 mm Chamber height: ~200 mm Material: PVC or similar plastic Fluid: water Flow type: tangential inlet jets generating vortex circulation ...

I am developing a two-stage, foldable telescopic leg mechanism and need a complete, manufacturing-ready CAD package. My top concern is that the final solution can be assembled and operated effortlessly in the field, so the construction, joints, and locking method must be intuitive and tool-minimal. What I will supply you: basic dimensions and functional constraints once we start. What I need back from you: • Fully detailed 3D model (STEP) • Priority DXF files and flat-pattern sheet-metal layouts for laser cutting • Complete assembly and exploded views with clear motion depiction • Structured BOM with materials, thicknesses, and hardware • Any supporting CAD that helps communicate the mechanism (native files welcome) Show me in your proposal how you pla...
I need a mechanical designer who can turn my concept for a small metal shed into a complete 3-D model that will keep sensitive industrial machinery dry and secure in an outdoor setting. After an initial call to clarify dimensions, and site constraints, you will translate the agreed layout into a fully detailed CAD assembly. The design could be built on 2.5 *2 meters concrete slab only; so, it is not big in nature. Please model all frame members, roof panels, fasteners, and flashing so I can generate fabrication drawings and a bill of materials directly from your file. I work mainly with SolidWorks, so native SolidWorks files are ideal, but STEP interchange works if you build with another professional package such as Inventor, Fusion 360, or CATIA. Once I confirm everything fits the site,...

I have a package of eleven 2-D drawings—each supplied in both DWG and PDF—that must be rebuilt as highly detailed 3-D models and exported as STEP files that open flawlessly in CAD software. Dimensional accuracy and faithful reproduction of every feature called out on the drawings are essential; these parts will go straight into production once the models are verified, so fillets, threaded and unthreaded holes, and any hidden or sectioned details must all be present. Because the manufacturing team uses SolidWorks assemblies for their workflows, I need : • Separate STEP files for each individual component, named to match the original drawing titles. Timing is critical. Let me know how quickly you can turn around the first model so I can confirm we are on schedule for the ...

I need a clean 3-dimensional layout of our new bottling facility so my engineering team can finalise space planning and line design. The model only has to show the production line plus the storage / warehouse zones; office or admin areas are out of scope for now. A basic level of detail is fine—major equipment, drainage point, electrical points, floor footprints and aisle clearances are what matter most—so there is no need to model every pipe or electrical tray. Please build the layout in a mainstream CAD or 3D package (AutoCAD Plant, SolidWorks, Revit, SketchUp or similar) and supply both the native file and an exported STEP or IFC so we can pull measurements directly. The dimensions and equipment list will come from me as soon as we start, and I’ll stay available for q...
