Pros & Cons

O-Calc Pro logo
O-Calc Pro

Pros

  • Wind sweep across all 360 degrees finds the worst-case loading direction without the engineer having to set it by hand.
  • Covers many loading codes, including NESC 2023, GO 95, CSA 2020, and AS/NZS 7000.
  • Catalog-driven drag-and-drop 3D modeling speeds up building joint-use and make-ready models.
  • Photogrammetry measurement tool takes attachment heights and wire sizes from photos.
  • The 2024 database add-on adds pole data history and a network connectivity view.

Cons

  • No public pricing; both the base software and the add-ons need a quote.
  • Covers only pole structures, not general asset maintenance.
  • Very few independent user reviews, so the vendor's accuracy and cost claims cannot be checked.
  • The database and connectivity features cost extra on top of the base license.

Pros

  • No licence fees on any number of seats, under the GPLv2+ open source licence.
  • Python and C++ plugins let teams add custom tools and database connectors such as PostGIS.
  • It reads many data formats and standard web services, which makes it easy to connect to existing data.
  • Its print layout, atlas and report tools suit organisations that produce a lot of maps.
  • It loads LAS, LAZ and virtual point cloud datasets with classification-based rendering.

Cons

  • Capterra reviewers report slow performance, freezes and crashes on heavy workloads.
  • Newcomers describe a steep learning curve and say installation can be difficult.
  • There is no vendor-backed support contract; help comes from the community or third-party providers.
  • It cannot edit point clouds and has no asset maintenance features such as work orders.
  • Some reviewers say it lacks tools that ArcGIS Pro offers.
