The short version

  • Only OpenSCAD has a free tier, so it costs nothing to try first.
  • 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.; OpenSCAD script-based workflow, not interactive design interface
  • They diverge on capability: Bentley iTwin Capture Modeler covers Aerial triangulation, OpenSCAD covers Script-based modeling.
  • 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.

OpenSCAD

  • Script-based workflow, not interactive design interface
  • Limited to constructive solid geometry and 2D extrusion modelling
  • Not suitable for artistic 3D modelling or computer animation
  • Complex build dependencies (Qt, CGAL, Boost)

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.

OpenSCAD: What is the cost of OpenSCAD?

OpenSCAD is free software with no licensing fees, subscriptions, or costs of any kind. The software is available as open-source with no restrictions on commercial or non-commercial use.

Source
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.

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.

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.
