The short version

  • Each has a real cost: Arnold the Internet Archive's capture of Autodesk's Arnold overview page on 30 December 2022 stated a subscription can be installed on up to 3 computers or devices, though only the named user may run it on one machine at a time, and includes access to the 3 previous major versions.; CoreTechnologie no pricing is published and the vendor sells through direct and regional channels, so there is no list price to anchor a negotiation and quotes differ by territory.
  • They diverge on capability: Arnold covers Ray tracing, CoreTechnologie covers Native CAD conversion.
  • Prices and features above were last checked on 31 August 2026.

  • VFXnot CoreTechnologie

CoreTechnologie

  • A tier supplier that receives CATIA from one customer and NX from another and must work in SolidWorksnot Arnold
  • A company migrating a CAD library off one platform and needing feature-recognised, editable models rather than dumb solidsnot Arnold
  • Preparing additive builds from exact B-rep geometry where STL faceting would lose the tolerance you neednot Arnold
  • Giving purchasing and manufacturing staff a viewer with real analysis without buying them CAD seatsnot Arnold

Where each one falls short

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

Arnold

  • The Internet Archive's capture of Autodesk's Arnold overview page on 30 December 2022 stated a subscription can be installed on up to 3 computers or devices, though only the named user may run it on one machine at a time, and includes access to the 3 previous major versions.

CoreTechnologie

  • No pricing is published and the vendor sells through direct and regional channels, so there is no list price to anchor a negotiation and quotes differ by territory.
  • Licensing is granular by format read and write pair, so the price you were quoted covers the translations you named and adding a customer with a different CAD platform later means going back for another line item.
  • It is a small independent vendor, so a buyer standardising a critical migration pipeline on it should weigh the concentration risk and check the support arrangement in their own region rather than assume global coverage.
  • Feature recognition on converted geometry works well on prismatic machined parts and much less well on complex freeform surfaces, so the rebuilt-as-editable claim needs testing on your own worst parts, not on a demo model.
  • 4D_Additive competes with entrenched incumbents such as Magics in industrial AM, so machine-side Build Processor support and bureau familiarity are thinner, which matters if you need your service provider to accept the output.

Answered from the vendors’ own pages

Arnold: How much does Autodesk Arnold cost?

Autodesk Arnold pricing is not published on the vendor website. Arnold is available through Autodesk subscription plans or standalone licensing. Customers should contact Autodesk directly for pricing quotes.

Source
CoreTechnologie: Is CoreTechnologie owned by a CAD vendor?

No. It is an independent German company, which is the main reason it appears in supply chains that must move data between competing CAD platforms.

Arnold: Is Arnold free for educational use?

Yes, Autodesk provides free educational licenses for Arnold to students and educators. Educational access allows learning of professional rendering capabilities at no cost.

Source
CoreTechnologie: Does conversion produce editable models?

3D_Evolution has feature recognition that rebuilds parametric features from solids. It is reliable on prismatic machined geometry and weaker on complex freeform surfaces, so test it on your hardest parts.

Arnold: What does Arnold render?

Autodesk Arnold is an industry-standard photorealistic rendering engine used for visual effects, animation, and design visualization. It supports GPU and CPU rendering with advanced features for film, television, and product design.

Source
CoreTechnologie: What makes 4D_Additive different from a normal slicer?

It prepares builds on exact B-rep geometry rather than converting to STL first, so tolerance and surface accuracy are not lost to faceting before printing.

CoreTechnologie: Can it run unattended for large migrations?

Yes. Batch and server conversion is designed for high-volume migration and PLM pipeline use rather than desk-by-desk conversion.
