Redline Pro 1.0.0 — Official Release
We are excited to announce the official 1.0.0 release of Redline Pro, a standalone, client-side engineering review workbench and drawing comparison studio.
Redline Pro brings fast drawing diffing, full PDF markup capabilities, bi-directional CAD conversion, and industrial PCB CAM inspection into a single desktop application—completely offline with zero external network dependencies and zero telemetry.
Highlights & Key Features
-
A/B Drawing Compare & Registration:
- Sub-pixel automated alignment detecting translation
(dx, dy)and rotational skew. - 3-Point Fiducial Snap for matching reference points across schematic revisions.
- Real-time 60 FPS Split Curtain slider and 4x Loupe inspector.
- Jump-to-Defect navigator with noise filtering and checklist triage (
Open,Approved,Flagged,Ignored).
- Sub-pixel automated alignment detecting translation
-
PDF Studio & Engineering Typography:
- Direct on-page inline WYSIWYG text editing and annotation.
- Streamlined Font & Paragraph ribbon with unified point-size selection (8–72 pt + custom sizing) and stepping controls.
- 18+ built-in engineering typefaces plus on-the-fly
.ttf,.otf, and.woffcustom font loading. - ANSI/ISO scalloped revision clouds, multi-point leader callouts, and cryptographic SHA-256 verification stamps.
-
Bi-Directional AutoCAD DXF Engine:
- Export vector PDF drawing paths and text directly to AutoCAD R12/2000 ASCII
.dxf. - Support for engineering units (
mm,mils,in) and standard scale presets (1:1, 1:50, 1:100, 1:1000). - Client-side parsing and rendering of
LINE,POLYLINE,LWPOLYLINE,CIRCLE,ARC, andTEXT/MTEXTentities.
- Export vector PDF drawing paths and text directly to AutoCAD R12/2000 ASCII
-
Industrial PCB CAM Inspection:
- Native Gerber RS-274X parser handling custom apertures, macros, step-and-repeat, and dark/clear polarity.
- Excellon NC Drill parser with tool tables and routed slot support (
G85). - Automated IPC Class 1/2/3 DFM clearance checks flagging spacing violations under 4 mils (0.1 mm).
-
Calibrated Measurement & Magnetic OSNAP:
- Scale calibration against known drawing dimensions in English (
mil,in) and Metric (mm,µm) units. - Point-to-point distance, multi-segment cumulative polylines, and shoelace polygon area calculations.
- 8px Magnetic Object Snap (OSNAP) targeting endpoints, midpoints, intersections, and centers.
- Numbered inspection badge placement with automated BOM tally lists and CSV export.
- Scale calibration against known drawing dimensions in English (
-
Performance & Data Privacy:
- 512×512 virtual tile rendering with LRU cache disposal to handle massive A0/E-size sheets without memory leaks.
- Background Web Worker thread offloading for pixel diffing and connected region clustering.
- 100% offline and air-gapped—your files never leave your machine.
- Portable
.redlinesession saves and multi-page executive PDF audit report generation.
