The multi-vendor professional software landscape engineers work across every day — CAD (SolidWorks, CATIA, Creo, Fusion 360, Inventor, Siemens NX), FEA/CFD simulation (ANSYS, Abaqus, COMSOL), MATLAB & Simulink, PCB/EDA design (KiCad, Altium, LTspice, PSpice), AutoCAD 2D drafting, and GIS (ArcGIS, QGIS) — explained and honestly compared.
Searchable shortcut reference across SolidWorks, AutoCAD, ANSYS, MATLAB, Revit, and KiCad — filter by software or action.
Which CAD, simulation, and PCB tools read and write STEP, IGES, Parasolid, STL, DWG, DXF, Gerber, and more — plus a quick export-format picker.
Answer a few questions about your discipline and task, and get a recommended CAD, simulation, or EDA tool with the reasoning behind it.
Compare subscription vs perpetual-plus-maintenance licensing over time using your own vendor-quoted prices, and find the breakeven year.
Get a general RAM/CPU/GPU/storage sizing tier for CAD, FEA/CFD, PCB, or rendering workloads based on model complexity.
CAD proficiency in mechanical design and drafting roles is commonly proven through vendor certifications rather than a licensure exam: Dassault Systèmes' SOLIDWORKS Associate (CSWA) and Professional (CSWP) credentials, and Autodesk's Certified Professional: AutoCAD exam. This overview maps what each covers, who administers it, and how they ladder together.
CSWA prep: sketch relations, extrude/revolve/sweep/loft, assembly mates and degrees of freedom, drawing views, and basic SOLIDWORKS Simulation concepts.
CSWP prep: multibody parts and equations, top-down in-context assembly design, design tables, sheet metal flanges and flat patterns, and basic surfacing tools.
AutoCAD ACP prep: drawing setup and units, layer/linetype management, precision drawing (osnap, polar tracking), blocks and attributes, layouts/viewports/plotting, and dimensioning standards.
