To learn 3D modeling in 101, start with free, beginner-friendly software (Blender, Tinkercad) and master core basics: move/rotate/scale tools, extrusion, and subdivision—this forms your foundation.
Focus on small, tangible objects (e.g., a mug from a cube, a chair from primitives) to practice translating 2D ideas into 3D space—simple projects build confidence without overwhelm.
Add basic UV unwrapping (for texture prep) next, and tie it all together with short, result-driven tutorials (like a 15-minute Blender cup tutorial)—this reinforces skills and gives you a tangible result to build on.
