Day 12 of Learn Autodesk Fusion 360 in 30 Days — Slotted Screwdriver

Why this is in the vault

Day 12 of the Product Design Online 30-day Fusion series, kept warm against the digital-manufacturing learning track (channel added 2026-05-11 per decision-page approval alongside cnc-kitchen and teaching-tech). Pure procedural CAD instruction — no SC-article seed, no concept candidate, no contradictions to vault positions. Filed for completeness so the series-with-transcripts index stays continuous; if the founder ever moves on the digital-manufacturing track, the gap (Days 1-10) becomes the obvious backfill.

Episode summary

Day 12 of Product Design Online's 30-day Fusion 360 series (2026 edition). The lesson builds a three-part flathead screwdriver (handle, shank, tip) inside a single hybrid design file, introducing the three-point arc, circular pattern, solid mirror, horizontal/vertical constraints, and intersect tool for referencing existing geometry across components. Heavy use of multi-component organization (one component per manufacturable part) and best-practice workflow ("keep sketches simple and manageable", "always know which component is active").

Key arguments / segments

[00:00:13] Start with hybrid design intent. Creates a new hybrid design file because the screwdriver contains both a plastic handle and a metal shank — different manufacturable parts.
[00:00:26] Create one component per part. Component-first organization: handle, shank, tip — each at the same hierarchical level (clear the parent selector before creating each).
[00:01:37] Handle: 28mm diameter cylinder, 100mm extrude on the XY plane.
[00:02:02–00:03:12] First grip cutout. Sketch on the back face, center-circle with coincident constraint to the cylinder edge, horizontal constraint to fully define, half-cut into the body to create the groove (-75mm directional extrude).
[00:03:12–~00:06:00] Circular pattern of grip cutouts around the handle — the lesson's first introduction of the circular pattern command.
[~00:06:00–00:10:00] Shank component. Cylindrical metal shank, joined to handle.
[00:10:00–00:12:30] Tip component (sketchless extrude). Extrude directly from the end face of the shank without a new sketch — works for simple cases, downside is no sketch in the timeline to alter later.
[00:12:42–00:14:30] Three-point arc tool (lesson centerpiece). On the YZ plane, place first point near front edge, second point on top edge (snap), third point free. Apply vertical constraint between first endpoint and top edge to force it onto the front edge. Dimension: 0.5mm offset, 9mm distance, 18mm radius. Line-close the sketch profile.
[00:14:15] Symmetric extrude + extent-type "all" — builds intelligence into the model so it cuts through regardless of future shank/tip diameter changes.
[00:14:38–00:15:06] Solid mirror tool. Mirror the extrude across the XY origin plane of the tip component using the "optimize" option for performance.
[00:15:06–00:15:20] Appearances pass. Apply different plastic appearances to handle, metal to shank — appearances can be applied per-face.
[00:15:20] Day 13 preview — fully defining sketches and why it matters.

Notable claims

"Keep your sketches simple and manageable" — best-practice repeated. Argues for many small sketches over few complex ones, easier to alter downstream.
"Always know which component you have active" — the radio-button-in-browser pattern. The single most common Fusion mistake is unintentional geometry on the wrong component.
Sketchless extrude is fine for simple cases but loses timeline editability — explicit tradeoff called out.
Extent-type "all" plus symmetric extrude = parametric robustness against future dimension changes.

Mapping against Ray Data Co

Weak mapping. This is pure procedural CAD instruction filed for the digital-manufacturing learning track (channel added 2026-05-11 per decision-page approval, along with cnc-kitchen and teaching-tech). No SC-article seed, no concept-article candidate, no contradiction to vault positions. Filed for completeness and to keep the learning-track signal warm — if Ray ever sits down to learn Fusion, the series-with-transcripts index is the on-ramp.

Series progress note: Day 12 of 30. Earlier days are not yet in the vault (state file shows pa6VWGFoZ2Q / Day 11 as the cursor from 2026-05-06). If the founder ever moves on the digital-manufacturing learning track, the gap (Days 1–10) should be backfilled.
