Possible challenges before choosing this path.
Customer changes, testing failures, production issues, supplier feedback, and cost targets may require repeated design revisions.
A design that looks correct in CAD may fail during machining, molding, welding, assembly, or inspection if DFM is weak.
Small drawing errors, wrong tolerances, missed material notes, or BOM mistakes can cause production delays and cost losses.
Employability may depend heavily on CAD tools used by the target industry, such as CATIA, SolidWorks, Creo, NX, or AutoCAD.
Prototype or validation failures can delay launch schedules and require urgent redesign, analysis, or supplier changes.
Engineers must balance strength, weight, cost, manufacturability, appearance, reliability, and customer requirements.
