DRFTING

Notes from the drawing board of a spacecraft mechanical engineer — tolerances, flat patterns, feature control frames, and the occasional exploded view. Every post is issued as a sheet.

CLEAN SHEET.

Orbital Drafting is a working notebook where spacecraft engineering meets computer-aided design. Each entry is treated like a released drawing: numbered, revised, and dimensioned. No post goes out without a figure, and no figure goes out without a centerline.

Topics orbit around mechanical CAD practice for space hardware — modeling strategy, tolerance stacks, flat patterns, drawing standards — written for people who read title blocks for fun.
