The differences that matter most
They differ most on price published. HELIOS 3D publishes Not publicly disclosed; HelioScope publishes USD 159. They use different pricing models, so those figures do not compare directly.
We do not name a winner. Below are 28 differences drawn from the same sourced dataset that powers both product pages.
Verified against the vendor’s own pages.
These cannot be compared on a single number
HELIOS 3D is priced quote-only and HelioScope is priced capacity-tiered. These are different pricing models, so a single side-by-side figure would be misleading. Each is shown as its vendor states it.

28 differences, ordered by how much they are likely to matter — pricing transparency first, then capabilities the vendor explicitly confirms or denies.

Scroll the table sideways to see both products. The capability column stays in place.
Framed as requirements, not a verdict. Both descriptions come from the same data.
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.
Full HELIOS 3D profileFor C&I designers and engineers who need a layout, a bankable-grade production estimate and a sales proposal without leaving one tool. Not for residential one-roof sales work (the same vendor routes that to Aurora) and not for jobs above 30 MW DC — the vendor publishes a hard design-size cap on every tier.

They differ most on price published. In total we recorded 28 verified differences and 9 points where they are the same.
HELIOS 3D is priced quote-only and HelioScope is priced capacity-tiered. These are different pricing models, so a single side-by-side figure would be misleading. Each is shown as its vendor states it.
We do not name a winner. Both are described from the same verified data, and which suits you depends on your requirements — the differences above are the facts; the choice is yours.

This comparison is generated from the feature database, not written by hand. A pair is only published when the data holds at least five stateable differences — which is why 281 candidate pairs were refused. How comparisons are built
