NWD Auto Encryption Tool
Batch encrypt RVM, VUE and NWD exports with unattended background processing
A Windows desktop tool for engineering model handover: batch re-save RVM, VUE and NWD into password-protected NWD with expiry. Folder watch, scheduled jobs and team notifications for design institutes and EPC delivery workflows.
Use cases
Manual encryption at handover is slow and easy to miss. The tool chains watch, convert, encrypt and notify into a repeatable pipeline that cuts rework and delivery risk.
Folder watch
Watches folders and processes new models as they arrive; scheduled scans when you need them.
Format conversion
Navisworks, Assimp and rvmparser engines covering NWD, FBX, GLB, OBJ, DAE and other common exchange formats.
Live feedback
Traceable processing logs and pass/fail statistics; notifications to WeCom, DingTalk or Feishu groups.
Core capabilities
Dual encryption engines
Selects the best path by installed Navisworks version: CLI for 2027+, API plugin for 2023–2026; plugins adapt when moved to a new machine.
Write-completion detection
Detects files still being written and waits until stable; wait time scales with size to avoid processing incomplete exports.
Incremental & dedup rules
Date-range filters, latest-wins for duplicates, MD5 skip for processed files; falls back to mtime when filenames lack dates.
Property carry-over
RVM attribute databases and matching VUE XML are detected and embedded so delivered NWD opens with usable properties in Navisworks.
Integrated model toolkit
Format conversion, encryption checks, version convert, batch rename, property/screenshot export, merge and diff — common handover tasks in one tool.
Long-run reliability
Single-instance execution; automatic exception logging and timeout cleanup for unattended batch runs.
