HELIOS 3D or PlantPredict?

They differ most on price published. HELIOS 3D publishes Not publicly disclosed; PlantPredict publishes Could not verify. They use different pricing models, so those figures do not compare directly.

We do not name a winner. Below are 20 differences drawn from the same sourced dataset that powers both product pages.

Verified against the vendor’s own pages.

Pricing

These cannot be compared on a single number

HELIOS 3D is priced quote-only and PlantPredict is priced on an unrecorded basis. These are different pricing models, so a single side-by-side figure would be misleading. Each is shown as its vendor states it.

Which might suit you

Framed as requirements, not a verdict. Both descriptions come from the same data.

Consider HELIOS 3D if…

  • you work at utility scale

For utility-scale project developers, EPCs and engineering firms that already own a Civil 3D estate, have IT able to run and back up a SQL Server instance, and need a layout that survives into earthworks and pile-driving coordinates. Not for anyone who wants a browser tool, a price they can read, a trial they can self-serve, a rooftop or residential workflow, or a licence that survives losing a USB stick — the vendor's own help centre says losing the dongle "will result in the irrevocable loss of your license" and recommends buying electronics insurance.

Consider PlantPredict if…

  • you work at utility scale

For utility-scale energy modellers and IEs who want a browser tool with unlimited projects, a documented algorithm set their lender's IE can audit, and automation. **Not for residential or C&I rooftop sales work, not for** teams that need layout-to-construction CAD (Design Pro is GIS-based, not an AutoCAD product), and not for anyone taking the site's structured data at face value — its schema publishes a price that its own pricing page contradicts.
