Enact or HELIOS 3D?

They differ most on price published. Enact publishes USD 279; HELIOS 3D publishes Not publicly disclosed. They use different pricing models, so those figures do not compare directly.

We do not name a winner. Below are 29 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

Enact is priced per-seat and HELIOS 3D is priced quote-only. 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 Enact if…

  • AI-assisted workflows matter to you
  • you work at utility scale
  • your work is mostly residential

Installers who want one vendor for sales design, permit-grade engineering and post-install monitoring, and who will pay for those as three separate line items. It is not a single unified product: the "end-to-end platform" announced in January 2026 is, as sold on 2026-09-25, three priced modules — one of which still lives on a separate domain under a separate brand, with its own pricing pages that disagree with Enact's.

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.
