The short version

  • Each has a real cost: Inventor pricing shown as template variables on the page, suggesting dynamic or region-specific pricing; 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: Inventor covers Parametric modeling, nTop covers Implicit modelling.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

Where each one falls short

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

Inventor

  • Pricing shown as template variables on the page, suggesting dynamic or region-specific pricing
  • No clear pricing information readily available on the overview page

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.

Answered from the vendors’ own pages

Inventor: How much does Autodesk Inventor cost?

Autodesk Inventor pricing is not displayed on the overview page. Monthly and annual subscription options are available, including single-year and multi-year terms. Customers can access pricing through their Autodesk Account or contact sales.

Source
nTop: Is nTop the same company as nTopology?

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

Inventor: Is there a free trial for Autodesk Inventor?

Yes, Autodesk offers a 30-day free trial of Inventor. You can start your project and try the software for free during this period.

Source
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.
