Pros & Cons
PPLS-CADD
Pros
- Bentley says it is used by more than 1,600 organizations in over 125 countries, and the acquisition announcement called it the US industry standard for transmission line design.
- Combines terrain modeling, sag-tension and thermal ratings (IEEE 738 and CIGRE 207) in one tool.
- Imports and classifies large LiDAR point clouds, and its AMBER tool builds line models from them automatically.
- Plan and profile drawings regenerate automatically when the design changes.
- Links directly to PLS-POLE, TOWER and the SAPS finite element engine for structural checks.
Cons
- No public pricing; buyers must request a quote.
- Bentley recommends about five days of training, so new users face a steep learning curve.
- Runs on Windows only.
- Covers design only: there are no work orders, maintenance or field inspection tools.
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.
