Changelog - BlastCAD

August 2026

v1.0.5 — Blast Analysis Heatmaps

New Timing Map heatmaps — overlay the pattern with seven analysis modes: breakage coverage, powder factor (kg/m²), timing isochrones, burden relief, PPV/vibration, Kuz-Ram fragmentation (X₅₀), and delay-scatter overlap risk.
New Ground vibration (PPV) — drop a draggable monitor point to read predicted peak particle velocity, with cooperating-charge (MIC, 8 ms rule) grouping and an exclusion ring at your compliance limit.
New Rock movement vectors — per-hole muck direction toward the free face opened by earlier-firing holes, for quick relief and throw checks.
New Burden relief map — see, per hole, the distance to the newest free face at its firing time, exposing choked or over-confined holes.

August 2026

Imp Global CDN delivery — the app, fonts, sounds, and 3D libraries are now served from a worldwide edge CDN (Cloudflare R2), cutting load times for users across every region.
Imp Self-hosted typography — the Inter typeface is now delivered from our own CDN instead of Google Fonts, improving privacy and removing a third-party dependency.
Imp Lighter icon system — replaced the Font Awesome web font with inline SVG icons, removing a render-blocking external stylesheet for a faster first paint.
New Refreshed detonation sounds — an updated blast simulation sound library for playback.

July 2026

Fix Timing Plan delay=0 — holes assigned delay 0 now sync correctly to BlastCAD; previously the value was lost on re-sync due to a JavaScript falsy check.
Fix Light theme in wizards — Ring Wizard, Charge Wizard, Bench Wizard, Tunnel Wizard, Ring View, Section Plane panel, and all report modals now correctly inherit the light or dark theme regardless of portal mounting point.
Fix Ring View delay colour — holes with delay = 0 were incorrectly shown in the unassigned colour; they now render on the delay gradient.
Fix Drill Plan Report — DIP and DUMP orientation dials simplified to show average values only, removing per-hole needle clutter. Flip-horizontal now defaults to enabled.
Imp Report modals — Shopping List, Logging Sheet, Charge Sections, Cover Page, and Charge Checklist now correctly follow the system theme (chrome/desk area) while keeping the paper area always white for print fidelity.
Imp Print and Close buttons standardised across all report modals.

June 2026

New Tunnel Blast Wizard — generate full tunnel face patterns (burn/wedge/fan cut, easers, stoppers, contour, lifter) from a single parameter set.
New Bench Blast Wizard — generate open-pit bench patterns on a row or staggered grid, or trace directly over a CAD polyline boundary.
New Face Profile Analyser — import a drone or LiDAR point cloud and compute per-hole actual burden versus designed burden, flagging underburden and overburden zones.
New As-Drilled Import — load survey CSV files (collar/toe in absolute coordinates) and overlay as-built hole positions against the design in the 3D viewer.
New Fan Chart — print a scaled A4 fan chart for any ring section directly from the ring workflow.
New Blast Record Sheet — fill in site metadata and print a one-page shot record with full hole and charge summary.
New Lilly Blastability Index — automatic rock factor A calculation from rock mass descriptors (RMD, JPS, JPA) feeds directly into Kuz-Ram fragmentation estimates.
New Site calibration endpoints for PPV, fragmentation, and flyrock constants using OLS and Bayesian updating against observed blast records.
Imp Backend restructured into focused routers — faster cold-start and easier to extend per module.
Imp Rate limiting now correctly resolves the real client IP behind Cloudflare proxies.

May 2026

New Launched BlastCAD with full 3D underground blast design — draw holes, assign charges, simulate detonation sequences in the browser.
New Ring workflow — five-step guided process from DTM selection through baseline, ring placement, hole design, and summary.
New Import from Deswik CSV, Datamine, Surpac, DXF, LandXML, and GeoTIFF/ASCII Grid DTMs.
New LAS and XYZ point cloud loading with real-time display in the 3D scene.
New Charge Plan — segment-based explosive loading with bulk, packaged, and inert products; templates for repeating patterns.
New Advanced blast analytics — Holmberg-Persson PPV, Kuz-Ram/JKMRC fragmentation, Kleine 4D energy, Monte Carlo timing scatter, and Lundborg flyrock zones.
New 2D CAD tools with full grip-editing, offset, trim, mirror, and hatch fill — all with undo/redo.
New Section plane slicer, measure tool, and block model viewer with PPV colour mapping.
New Auto tie-up — chevron and zigzag delay propagation across selected holes.
New Client-side autosave to IndexedDB with crash recovery on next launch.
