nTop
CAD
Implicit computational design for lattices, heat exchangers and topology-driven parts

The short version
- Each has a real cost: Modo foundry announced on November 7, 2024 that it is winding down development of Modo after the Modo 17.1 release, with no further feature or maintenance releases anticipated; 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: Modo covers Polygon modeling, nTop covers Implicit modelling.
- Prices and features above were last checked on 31 August 2026.
Where they differ
Only the attributes on which Modo and nTop actually diverge.
Identical on both: free tier (No), user rating (Not yet rated), category (CAD).

What people use each for
The jobs each tool is most often brought in to do.
Modo
- Polygon and subdivision surface modelling for media and entertainment assetsnot nTop
- Look development and rendering of product and character modelsnot nTop
nTop
- Designing a variable-density lattice bracket where mass must drop without losing stiffness in the loaded regionsnot Modo
- Generating a heat exchanger with thousands of internal channels that a conventional CAD kernel cannot representnot Modo
- Producing patient-specific implant geometry with porous surfaces at scale rather than one at a timenot Modo
- Automating a family of parts as a reusable design workflow that reruns when the load case changesnot Modo
Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Modo
- Foundry announced on November 7, 2024 that it is winding down development of Modo after the Modo 17.1 release, with no further feature or maintenance releases anticipated
- Support continues only until each customer's current contract term expires
- Foundry does not guarantee that Modo will keep working on future operating system updates because no patches will be issued, and recommends customers migrate to alternative 3D workflows
- Perpetual licences keep working but receive no further updates, bug fixes or support
- The Modo forums closed in December 2024 and downloads, docs and the support knowledgebase were committed only until November 2025
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 Modo or nTop better?
- Neither clearly leads. Modo starts at $29/month and nTop at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Modo or nTop?
- Modo starts at $29/month and nTop at On request.
- Does Modo or nTop run on more platforms?
- Modo runs on Windows, MacOS, Linux. nTop runs on Windows, Cloud.
- What is Modo best used for?
- Modo is most often used for polygon and subdivision surface modelling for media and entertainment assets, look development and rendering of product and character models. Of those, polygon and subdivision surface modelling for media and entertainment assets and look development and rendering of product and character models are not what nTop is typically brought in for.
- What can Modo do that nTop cannot?
- Modo covers Polygon modeling, Subdivision surfaces, Sculpting, UV tools. nTop covers Implicit modelling, Lattice and cellular structures, Field-driven design, Integrated simulation.
Answered from the vendors’ own pages
nTop: Is nTop the same company as nTopology?
Yes. nTopology rebranded to nTop. The product is the same lineage.
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.
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.
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.
