nEVEn: Model Protection & Performance Intelligence
What is nEVEn?
nEVEn (palindrome pronounced "uneven") is the dedicated caretaker, protector, and performance intelligence engine for your SketchUp projects.
In computer science, music, and nature, palindromes (sequences that read the same backward as forward) represent fault-tolerant, self-stabilizing structures - from bidirectional algorithms to self-repairing DNA sequences that bind and excise corruption. Symmetrically anchored as [n] - E V E - [n] around a central vertex, nEVEn brings that exact structural equilibrium to 3D design. It transforms chaotic, uneven SketchUp models into balanced, high-performance assets, while empowering architects to travel forward into new revisions and backward into past restore points with zero risk of corruption.
In professional 3D design and modeling workflows, SketchUp models continuously accumulate invisible strain: fragmented geometry, oversized textures, duplicate groups, and corrupted internal entity records. Over active hours, this hidden load manifests as the classic, dreaded architectural workflow nightmares:
- SketchUp "Not Responding" Freezes: Viewport suddenly locking up white during zoom, orbit, copy-paste, or complex group edits.
- Fatal File Corruption Errors: Panic-inducing dialogs like "This does not appear to be a valid SketchUp model" or "File not found or failed to open" right before critical client submission.
- The Sudden Mid-Command BugSplat Crash: Unhandled memory overflows closing your session instantly without giving you a chance to save.
- Invisible Database & File Bloat: Files ballooning to hundreds of megabytes even after deleting geometry, caused by orphaned attributes and unused definitions.
nEVEn acts as an authoritative shield against these exact catastrophes - preemptively diagnosing entity strain, purging corrupt data structures, maintaining local visual version history, and ensuring your project opens cleanly every single time.

Topic Related FAQ
Do I need an internet connection to use nEVEn? ›
No. nEVEn operates 100% offline. Scans, cleanups, Crash Shield backups, and Checkpoints are stored locally on your hard drive. An internet connection is only briefly required during initial license key activation.
Does the Free Edition slow down or throttle large models? ›
No. nEVEn never artificially throttles scan speed or cleanup routines in the Free Edition. You get the exact same native C++/Ruby performance engine as Pro users. The limits apply strictly to volume (such as 2 active checkpoints per project or lifetime usage allowances on heavy batch operations).
What happens if I reach the 2 checkpoint limit in the Free Edition? ›
When you reach 2 checkpoints, your existing restore points remain fully protected. To capture a newer checkpoint, you can delete an older intermediate checkpoint or upgrade to nEVEn Pro for unlimited checkpoint capture across all your projects.
