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.; Siemens NX siemens NX offers only a 30-day free trial with no published subscription or perpetual license price; buyers must go through a sales process to get pricing, per the vendor's own product page.
- They diverge on capability: Bentley iTwin Capture Modeler covers Aerial triangulation, Siemens NX covers Advanced CAD.

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.
Siemens NX
- Siemens NX offers only a 30-day free trial with no published subscription or perpetual license price; buyers must go through a sales process to get pricing, per the vendor's own product page.

Questions people ask
- Is Bentley iTwin Capture Modeler or Siemens NX better?
- Neither clearly leads. Bentley iTwin Capture Modeler starts at On request and Siemens NX at $29/month, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Bentley iTwin Capture Modeler or Siemens NX?
- Bentley iTwin Capture Modeler starts at On request and Siemens NX at $29/month.
- Does Bentley iTwin Capture Modeler or Siemens NX run on more platforms?
- Bentley iTwin Capture Modeler runs on Windows, Cloud. Siemens NX runs on Windows, Linux.
- 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 Siemens NX is typically brought in for.
- What can Bentley iTwin Capture Modeler do that Siemens NX cannot?

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.
Siemens NX: Does Siemens NX offer a free trial?
Yes, Siemens offers a 30-day free trial of both Designcenter CAD and NX CAM software that is fully functional. Users can get a hands-on feel for the software without any financial commitment before purchasing.
SourceBentley 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.
Siemens NX: Is NX free for students?
Yes, Siemens offers free CAD/CAM Student Edition access to Designcenter and NX for students and educators. Academic offerings are available for those in educational institutions.
SourceBentley iTwin Capture Modeler: Can it process laser scan data as well as photographs?
Yes. It fuses point clouds with imagery in a single reconstruction.
Siemens NX: What licensing options does NX provide for different business sizes?
Siemens offers scalable licensing for startups, mid-size companies, and multinational corporations. Designcenter and NX CAM support flexible team-based licensing to match organizational size and manufacturing needs.
SourceBentley 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.
