Blender 3D
Blender is the leading open-source 3D creation suite covering modeling, sculpting, rigging, animation, rendering, video editing, and visual effects, used in engineering for product visualization, technical animation, and design communication. As a hard skill it requires fluency in Blender's non-destructive modeling workflow, materials and lighting for photorealistic rendering (Cycles, EEVEE), and the Python scripting interface for programmatic geometry generation. Design engineers apply Blender to produce high-quality product renders for proposals and marketing, create animated exploded-view assembly sequences, and communicate complex spatial relationships in ways that static CAD drawings cannot.
