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.; Carlson Software the perpetual licence is a larger upfront cost than a first-year subscription, which is harder to approve for a practice with tight cash flow even though it is cheaper over five years.
  • They diverge on capability: Bentley iTwin Capture Modeler covers Aerial triangulation, Carlson Software covers Survey data reduction.

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.

Carlson Software

  • The perpetual licence is a larger upfront cost than a first-year subscription, which is harder to approve for a practice with tight cash flow even though it is cheaper over five years.
  • It is Windows only, so a practice on macOS has to run virtualisation, and there is no browser or mobile design client.
  • Carlson is a smaller ecosystem than Autodesk, so hiring staff who already know it is harder and training time is a real cost when a new surveyor joins.
  • Skipping maintenance saves money but leaves you on an old release, and when a client eventually sends a file from a much newer version the compatibility gap becomes your problem to solve.
  • Pricing is largely sold through resellers with figures varying by dealer and region, so the published $4,450 Civil Suite price is a reference point rather than a firm quote.

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.

Carlson Software: Is Carlson a perpetual licence?

Yes. You buy it once and it keeps running. Annual maintenance at roughly ten per cent is optional and only affects updates and support.

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.

Carlson Software: Do I need AutoCAD as well?

No. An IntelliCAD engine is included. You can alternatively run Carlson on top of AutoCAD if your practice already licenses it.

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.

Carlson Software: Does Carlson field software work with other brands of instrument?

Yes. SurvCE supports total stations and GNSS receivers from several manufacturers, which is one of the main reasons firms choose it.

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.

Carlson Software: What does the Civil Suite include?

Survey, Civil, Hydrology and GIS, listed at $4,450.
