July 2026

v1.0.3 — UI Polish & Bug Fixes

  • 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

v1.0.2 — Pattern Wizards & Field Analysis

  • 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

v1.0.1 — Initial Public Beta

  • 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.
