The short version

  • Each has a real cost: IronCAD pricing page not found; 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: IronCAD covers Hybrid parametric/direct modeling, nTop covers Implicit modelling.
  • Prices and features above were last checked on 31 August 2026.

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

IronCAD: Where can I find IronCAD pricing?

IronCAD's pricing page is not available. Contact IronCAD directly through their website for CAD software licensing and pricing information.

Source
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.
