## Core Instruments

### 1. Karo.WhyHidden
- Role: Instant Revit Visibility Diagnostics & 1-Click Fixes.
- Problem Solved: In complex Revit projects, model elements frequently become invisible due to nested, overlapping view parameters. Manual troubleshooting takes 10–20 minutes across dozens of dialogs. WhyHidden diagnoses the exact cause in seconds.
- 16 Automated Checks:
  1. Direct hide (Hide in View -> Elements)
  2. Category hidden in Visibility/Graphics (VG)
  3. View filter overrides & Invisible Lines
  4. View range clipping (Cut plane, Top, Bottom, View Depth)
  5. Active Section Box boundary limits (3D views)
  6. Phase & Phase Filter mismatch
  7. Design Option assignment (non-primary option hidden)
  8. Workset visibility overrides
  9. Crop region boundaries
  10. Annotation crop boundaries
  11. Coarse/Medium/Fine detail level settings
  12. Temporary Hide/Isolate sessions
  13. View-specific 2D element placement
  14. Graphic Overrides with invisible line weights
  15. Linked RVT instance visibility
  16. Controlling View Template locks
- 1-Click Quick Fixes: Unhide element, reset invisible line overrides, restore temporary hide session directly from the diagnostic panel.
- Pricing: $9 / month or $69 / year (individual license).

### 2. Karo.WhatsChanged
- Role: Linked Model Change Auditing & Version Diffing.
- Problem Solved: When architectural, structural, or MEP consultants reload revised Revit link models, critical geometry shifts and parameter modifications often go unnoticed, causing clashes during construction. WhatsChanged tracks every modification locally.
- Core Capabilities:
  - 100% Local SQLite Diff Engine: Instant comparison without cloud uploading, project size limits, or model privacy exposure.
  - Geometry & Parameter Deltas: Pinpoints exact XYZ coordinate shifts, dimension deltas, type modifications, new additions, and deleted objects.
  - Visual Focus Dim: Isolates modified elements in active plan and 3D views while dimming unchanged context.
  - Automated 3D Section Box: Generates a tight 3D bounding box around modified structural nodes and MEP connections in one click.
  - Coordination Reports: Exports formatted Excel workbooks and meeting-ready PDF reports for subcontractor coordination meetings.
- Pricing: $15 / month or $120 / year.

### 3. Karo.ModelGuard
- Role: Real-Time BIM Error Prevention & Policy Enforcement for Teams.
- Problem Solved: Prevents Revit model degradation, corruption, and sync bloat in multidisciplinary teams before harmful edits reach the central model.
- Core Capabilities:
  - Intercepts High-Risk Actions: Blocks exploded AutoCAD DWG imports, unpinned grid and level deletions, unpinned RVT links, fake dimension overrides, in-place families, and unapproved external families.
  - Two Enforcement Modes:
    - StrictBlock: Hard intervention that cancels the destructive command immediately.
    - Justify: Requires the modeler to submit a mandatory text justification logged to the team record.
  - Shared Network Configuration: Distributes office BIM policies across local network shares (UNC) with automatic local cache fallback for offline/remote laptops.
  - Centralized Team Audit Log: Captures all policy violations and justified exceptions in a central SQLite audit trail for BIM Managers.
- Pricing: $99 / month or $990 / year for a 5-seat team license (transferable seats).

### 4. Karo.Segments
- Role: Parametric Flashing, Trims, Parapet Copings & Facade Detailing.
- Problem Solved: Eliminates repetitive 2D drafting for architectural sheet metal flashings, roof copings, sills, and facade reveals by snapping parametric 3D profiles directly to host geometry.
- Core Capabilities:
  - Interactive Host Snapping: Snaps to planar faces and edges of walls, roofs, and slabs with live 3D ghost preview and corner miter detection.
  - Unified Profile Catalog: Manages profile marks, custom dimensions, RAL color finishes, unfolded girth widths, and lap joint offsets.
  - 4 View Presentation Modes: Instantly switches between Check (color-coded), Construction, Drafting (clean B&W vector lines), and Hidden styles.
  - Automated Fabrication Schedules: Produces native Revit schedules with embedded profile diagrams and exports formatted Excel cut lists with images.
- Pricing: $19 / month or $149 / year.
