This is the biggest update to CNC NEXUS PRO yet — five major new tools added on top of everything from v2.1. G/M-Code Quiz Test your knowledge of over 60 G-codes and M-codes across 265 unique questions. Identify what a code does, pick the right code for a job, classify codes by category, match detailed descriptions, and answer real-world shop-floor application scenarios like "which canned cycle do you use for a 50mm deep hole needing chip-clearing retracts?" Every question displays the code as a large badge for instant visual reference. Material Library A comprehensive cutting parameter reference covering 22 materials across 8 categories — Aluminum (6061, 7075, 2024), Steel (1018, 4140, 4340), Tool Steel (D2, H13), Stainless (304, 316, 17-4 PH), Titanium (Grade 2, Ti-6Al-4V), Brass & Copper, Superalloys (Inconel 718, Hastelloy), Plastics (Delrin, Nylon, PEEK), and Cast Iron. Each material includes recommended SFM range, chip load, coolant type, hardness rating, and detailed machining notes from real shop experience. Tap Drill Chart 35 thread sizes covering UNC, UNF, and Metric standards from #2-56 through 1" and M2×0.4 through M30×3.5. Filter by thread system, search by size, and instantly see the correct tap drill and its decimal equivalent. Tolerance Stack-Up Calculator Add any number of part features with nominal dimensions and plus/minus tolerances. The calculator instantly computes both worst-case and RSS (statistical) stack-up results, showing maximum, minimum, and total variation. Entries can be added, edited, and deleted on the fly. Progress Tracker Track your quiz performance over time with a live score history chart, per-attempt breakdown, and summary stats showing total attempts, average score, and personal best. Scores persist between sessions and can be filtered by quiz type.

Completely Rebuilt GD&T Quiz — 5,000 Truly Unique Questions The GD&T quiz has been fully redesigned from the ground up. Every question is now genuinely different — no more repetition. Questions are generated using 14 parameterized templates covering symbol identification, datum reference frames, feature control frame reading, modifier meanings, tolerance-zone math with MMC bonus calculations, and symbol comparisons. Live Engineering Blueprint Renderer A major new addition: a significant portion of quiz questions now show a real engineering drawing you must read to answer. Blueprints are rendered live (no image assets) using SwiftUI Canvas and include part outlines with dimension lines and arrows, datum feature triangles with boxed letters (A, B, C...), hole and feature circles with centerlines and diameter labels, and feature control frame callout boxes. Every blueprint is unique to its question. Blueprint-Reading Question Types New question types test real drawing-reading skills: identify which GD&T characteristic is called out in a feature control frame on the drawing, read the exact tolerance value off the FCF, identify which datum letter appears on a specific edge of the part, determine the diameter of a highlighted feature, calculate the true-position distance between two hole centers, and read the full FCF (characteristic + tolerance + datum references) in one go. General Improvements Bug fixes to quiz answer correctness, improved question numbering, and performance optimizations to the question bank generator.
