O-calc Pro Line Design Now

Feature proposal: “Pro Line Design” for O‑calc

Goal

Add a dedicated “Pro Line Design” workflow that helps users create, edit, and export professional electrical/mechanical line diagrams (single-line and multi-line) with calculations, standards checks, and printable outputs.

O-Calc Pro Line Design is a specialized module within the Osmose O-Calc Pro O-calc Pro Line Design

O-Calc Pro Line Design is a powerful extension for the O-Calc Pro software that enables engineers to model and analyze entire circuits of utility poles simultaneously, rather than one individual structure at a time. This tool dramatically reduces modeling time for large-scale distribution projects. Core Functionality Feature proposal: “Pro Line Design” for O‑calc Goal

Case Study 3: Mountainous Terrain – 500 kV

In a steep Rocky Mountain corridor, manual sag calculations were failing due to uneven span lengths (200 ft to 1800 ft). O-calc Pro’s multi-span model captured the "strain pole effect" where long spans pull tension from short spans. It recommended adding two intermediate strain structures to limit vibration damage. After five years, no conductor fatigue has been observed. Detailed line report (PDF) – includes all inputs

• Detailed line report (PDF) – includes all inputs and results.
• Pole loading sheets – for field installation.
• Conductor stringing tables – sag values per span for linemen.
• Clearance diagrams – for permitting.

: Design entire lines (up to ~40 poles) rather than single structures. Geospatial Integration : Structures can be placed using Google Maps , or internal GIS data via Shapefiles and GeoJSON. Line Wizard
