Pros & Cons
PLS-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.
SPIDA
Pros
- Supports geometric nonlinear analysis, as well as linear analysis, for wood, steel, concrete, composite, and decayed poles.
- Comes with NESC, CSA, and GO95 code criteria already set up, and accepts custom load cases.
- Cloud batch processing lets large pole programs be analyzed at once.
- Scenario reruns and a design comparison tool make make-ready comparisons repeatable.
- A 30-day free trial is available, and students and educators get free access.
Cons
- Specialist scope: it is not a general maintenance or work order system.
- Preparing raw field data for modeling can slow projects.
- CAD-heavy teams may need extra steps to produce drawing deliverables.
- Enterprise and SPIDAstudio pricing is not published.
- Focused on North American codes and markets.
