Precision CAD Drafting for Competition Geometry Diagrams

I’m looking for a skilled CAD designer to produce 5 highly accurate geometric diagrams used in a competition setting where precision is critical and small drawing errors can cause large real world inaccuracies. This is technical CAD drafting, not graphic design. The designs are not complicated and I do not think they will take a lot of time for an experienced professional. Key requirements: • Accurate geometry, angles, distances, and centroid (Point E) calculation • Diagrams based on provided reference PDFs • Clear measurements in metres and centimetres • Perpendicular projection lines and angle annotations • Output as vector based PDFs (A2 & A4) to strict scales • Print accurate, 300 DPI, fonts embedded/outlined Software: AutoCAD, DraftSight, Rhino, SolidWorks, or similar Experience: CAD drafting, geometry, survey/technical drawings One diagram requires custom measurements; the others follow natural scaling. This project is accuracy critical. Please apply only if you’re confident in precision CAD work.

Accuracy, correct angles, and precise scaling are essential. This is a technical drafting task, not graphic design. The work must be produced using CAD or equivalent vector based software suitable for precise measurement and scaling. Project Overview • Create 5 irregular quadrilateral diagrams using provided PDFs as references • Each diagram includes points A, B, C, D, with Point E calculated as the centroid (centre of mass) • All points must be joined accurately with correct angles and labelled measurements • Diagrams will be used by contestants to physically place a stake on the ground based on the drawings Key Technical Requirements • Extreme accuracy in angles, distances, and centroid calculation • Clear measurement annotations in metres and centimetres • Distances and angles from point A to C, B, D, and E must be shown • Perpendicular (90°) dotted projection lines from top line (Z) and bottom line (Q) to Point E • Measurements shown along: o Top line (Z) o Bottom line (Q) o Dotted perpendiculars to E • All geometry must be mathematically correct and easy to interpret on-site Scaling & Output Requirements • A2 PDF (High Resolution) o Scale: 1 cm = 1 metre (10mm = 1m) o Saved at 100% / 1:1 • A4 PDF (Standard) o Scale: 5mm = 1 metre • All files: o Vector-based (no rasterised drawings) o 300 DPI o Layers flattened o Fonts embedded or converted to outlines • Each output must be labelled to match the supplied reference PDFs What I’m Looking For • Proven experience with CAD drafting (AutoCAD, DraftSight, Rhino, SolidWorks, or similar) • Strong understanding of geometry, angles, and scaling • Experience producing print-accurate technical drawings • Ability to work precisely from provided reference PDFs Important Notes • We are not designers, which is why we are hiring a professional • One diagram (Diagram 3) will require tailored measurements; others follow a more natural scale • This project is accuracy critical — please only apply if you are confident in precision CAD work If helpful, applicants are encouraged to share examples of technical or survey-style drawings they have produced previously.
