Pros & Cons
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.
QGIS
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.
