The short version

  • Each has a real cost: Bentley iTwin Capture Modeler the rename from ContextCapture is more than cosmetic: licensing moved into Bentley's subscription and consumption model, and existing perpetual users should confirm what a renewal converts to before assuming continuity of cost.; nTop nTop is a specialist tool that sits alongside mainstream CAD rather than replacing it, so you pay for an extra seat and accept a handoff between two geometry systems.
  • They diverge on capability: Bentley iTwin Capture Modeler covers Aerial triangulation, nTop covers Implicit modelling.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Bentley iTwin Capture Modeler

  • The rename from ContextCapture is more than cosmetic: licensing moved into Bentley's subscription and consumption model, and existing perpetual users should confirm what a renewal converts to before assuming continuity of cost.
  • Consumption-based entitlements make the cost of a large reconstruction hard to predict in advance, which is awkward when you are quoting a fixed-price deliverable to a client.
  • The desktop engine is Windows only and reconstruction is compute-hungry, so meaningful throughput needs either serious workstation hardware or paid cloud processing.
  • Bentley does not publish a plain rate card and pricing varies by region, reseller and existing agreement, so two firms buying the same thing can pay very different amounts.
  • Value compounds inside the Bentley ecosystem, and a firm whose design work happens in Autodesk or Esri tools pays for a positioning it will not use while getting the same mesh a cheaper standalone photogrammetry package would produce.

nTop

  • nTop is a specialist tool that sits alongside mainstream CAD rather than replacing it, so you pay for an extra seat and accept a handoff between two geometry systems.
  • Implicit modelling requires a different way of thinking from feature-based CAD, and the retraining period is long enough that unused licences are a common and expensive outcome.
  • No pricing is published and there is no free or hobbyist tier, so evaluation runs through a sales process and small teams cannot try it seriously without engaging.
  • Subscription only, with no perpetual licence, means the geometry logic you built stops being editable the day you stop paying, which is a real risk for long-lifecycle aerospace and medical programmes.
  • The output is most valuable when you have additive manufacturing capacity to make it; organisations without machines that can print the geometry end up designing parts nobody can produce.

Questions people ask

Is Bentley iTwin Capture Modeler or nTop better?
Neither clearly leads. Bentley iTwin Capture Modeler starts at On request and nTop at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Bentley iTwin Capture Modeler or nTop?
Bentley iTwin Capture Modeler starts at On request and nTop at On request.
Does Bentley iTwin Capture Modeler or nTop run on more platforms?
Both run on Windows, Cloud, so platform support will not decide this one for you.
What is Bentley iTwin Capture Modeler best used for?
Bentley iTwin Capture Modeler is most often used for a highway authority reconstructing a corridor from drone imagery for design work in openroads, a survey firm delivering city-scale textured meshes to a municipal client for planning and visualisation, an engineering consultancy fusing terrestrial laser scans with drone photography of a bridge for condition assessment, a team publishing streamable 3d tiles of a construction site so stakeholders can view it in a browser. Of those, a highway authority reconstructing a corridor from drone imagery for design work in openroads and a survey firm delivering city-scale textured meshes to a municipal client for planning and visualisation are not what nTop is typically brought in for.
What can Bentley iTwin Capture Modeler do that nTop cannot?
Bentley iTwin Capture Modeler covers Aerial triangulation, Dense mesh reconstruction, Point cloud fusion, Orthophoto and DSM output. nTop covers Implicit modelling, Lattice and cellular structures, Field-driven design, Integrated simulation.

Answered from the vendors’ own pages

Bentley iTwin Capture Modeler: Is ContextCapture discontinued?

The name is. The product continues as iTwin Capture Modeler within Bentley's iTwin family.

nTop: Is nTop the same company as nTopology?

Yes. nTopology rebranded to nTop. The product is the same lineage.

Bentley iTwin Capture Modeler: Does it still support a perpetual licence?

New buyers should expect subscription or consumption-based entitlements. Confirm the exact conversion path if you hold an older perpetual licence.

nTop: Does it replace SolidWorks or NX?

No. It is used alongside them. Mainstream CAD handles the conventional geometry and assembly; nTop handles the lattice, field-driven and complex internal structure work.

Bentley iTwin Capture Modeler: Can it process laser scan data as well as photographs?

Yes. It fuses point clouds with imagery in a single reconstruction.

nTop: Is there a free version?

No free commercial tier is published. Access runs through a demo and sales process, with academic programmes handled separately.

Bentley iTwin Capture Modeler: Do I need other Bentley software to use it?

No, output formats are usable elsewhere, but the commercial and workflow case is strongest if you already run MicroStation or OpenRoads.

nTop: Can I buy a perpetual licence?

No. It is sold as an annual subscription, so budget it as recurring cost across the life of the programme.
