The Problem

Every Revit crash leaves clues.
Most teams don't have time
to find them.

Revit journal files capture everything behind a crash, but they're buried in thousands of lines of technical logs. Ze'Diag analyzes the journal automatically, identifies the likely root cause, and delivers actionable insights in minutes instead of hours.

Diagnose in minutes, not hours

What used to take a BIM Manager 2–4 hours of manual journal reading is done in under 3 minutes. Upload, analyze, done.

Evidence-based root cause

No guessing. Ze'Diag extracts the exact command sequence that ran before the crash, identifies the failing component, and surfaces the warning signals that appeared in the build-up - all referenced back to specific journal lines.

Report-ready output

Download a professional PDF instantly. Share with your team, attach to an Autodesk support ticket, or keep for project documentation.

Catch recurring patterns

BIM Managers can run journals from multiple users and sessions to detect team -wide patterns - the same add-in flagged across machines, the same memory threshold hit on the same model, the same command sequence triggering failure. Individual diagnostics plus project-level intelligence.

Improve long-term stability

With clear root causes and actionable fixes, your team can address real problems - not symptoms and progressively reduce crash frequency.

Completely free. Always.

Ze'Diag is ZestineTech's free tool for the BIM community. No trial period. No feature limits. No subscription. Just download and use it.

How It Works

Three steps from crash to root cause

Ze'Diag handles the hard part - reading and interpreting the journal.
so your team can focus on fixing the issue, not finding it.

Upload your journal file

Locate the .txt journal file Revit created during the crashed session. Ze'Diag supports journal files from any Revit version that generates them.

Automated analysis

Ze'Diag scans the entire journal - all thousands of lines and extracts what matters: the exact command sequence before failure, system state and hardware load at crash time, all loaded add-ins cross-checked for known conflicts, and the full error chain.
