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.
Propeller
Pros
- Combines drone, LiDAR, GNSS rover and total station data on a single map, regardless of which hardware captured it.
- AeroPoints give survey-grade ground control without the manual surveying normally needed to set control points.
- Strong stockpile, cut and fill, and progress tooling, with a long track record in earthworks and aggregates.
- Integrates with common construction systems such as Procore, Trimble Connect, Autodesk Build and HCSS.
- The trust center shows a SOC 2 Type 2 attestation.
Cons
- No published software pricing, so buyers have to request a quote.
- Hardware such as AeroPoints and DirtMate adds separate costs on top of the software.
- Reviewers find less depth for vertical construction and interior fitout work.
- Some reviewers say the price may seem high to smaller clients.
