A quick look at what CableBlock is and what it can do for your team.
Close the Visibility Gap
During design, cable schedules in spreadsheets don't show how the network fits together. You only see rows and columns. Until now, the only way to see overall system topology was to redraw it in CAD or on paper.
Before CableBlock
- 50+ hours of manual diagram production per project
- Sequential review — one person at a time
- Version drift between schedule and diagram
- Procurement and installation may work from documents that no longer match the design
After CableBlock
- Diagrams generated automatically from schedule data
- Parallel review with real-time collaboration
- Single source of truth — schedule IS the diagram
- Changes flow through instantly, no manual sync
How It Works
From schedule to diagram in three steps. No manual drawing required.

Build your cable schedule from scratch in CableBlock, or import an existing CSV/Excel file. Smart column mapping handles the rest.
Collaborate & Validate
Edit together in real time. Track field-level changes with user attribution. Validate connections automatically as you work.
Visualize
Cable block diagrams generated instantly from your schedule. Drag to arrange, click to inspect, export to PDF when ready.
Built for Engineering Teams
Every feature designed for the way electrical engineers actually work on substation and industrial power projects.
Schedule Builder
Create cable schedules from scratch or import existing CSV/Excel files. Smart column mapping detects your data structure automatically.
Interactive Diagrams
Auto-generated cable block diagrams. Drag nodes to rearrange, zoom into sections, click cables for full metadata.
Real-Time Collaboration
Multiple engineers editing the same schedule simultaneously. See who is working where with live presence indicators.
Change Tracking
Field-level version history with user attribution. Know exactly who changed what, and when. Review with confidence.
Section Management
