The Problem: Disconnected Data

Electrical design relies on teamwork, yet spreadsheets create data silos. Storing schedules on a local hard drive creates a bottleneck where project teams and clients cannot access the real-time information they need to do their jobs.

The Status Quo: The Relay Race
The Process

One person holds the baton (the file). Everyone else waits.

The Risk

By the time the CAD team receives the PDF markup, the design has already changed.

The Result

Wasted meetings, conflicting drawings, and expensive backtracking.

The CableBlock Solution: The Live Workspace
The Workflow

Centralize your schedules in a secure, cloud-based workspace.

The Feature

Live Guest Links. Share read-only access with clients or contractors instantly—no login required.

The Value

Aligned Teams. Everyone sees the latest design, effectively eliminating "he-said-she-said" disputes.
