The short version

  • Each has a real cost: Bentley MicroStation bentley licensing has a history of usage-based true-ups, where running the software beyond your entitlement is permitted at the time and invoiced later, so finance teams get bills nobody in the design office authorised.; 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: Bentley MicroStation covers DGN modelling, CoreTechnologie covers Native CAD conversion.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Bentley MicroStation

  • Bentley licensing has a history of usage-based true-ups, where running the software beyond your entitlement is permitted at the time and invoiced later, so finance teams get bills nobody in the design office authorised.
  • It is Windows only, with no macOS or Linux build and no browser client, which rules it out for studios that have standardised on Mac hardware.
  • The user base is far smaller than AutoCAD's, so hiring a MicroStation operator is harder and slower in most markets and contract staff command a premium.
  • Value depends almost entirely on whether your clients mandate DGN; outside infrastructure and government work you are paying several times the price of mainstream CAD for a format nobody asks you for.
  • Agency workspaces, seed files and configuration variables make deployment a specialist job, and a firm working for several agencies ends up maintaining multiple incompatible configurations.

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.

Questions people ask

Is Bentley MicroStation or CoreTechnologie better?
Neither clearly leads. Bentley MicroStation starts at $2284/year and CoreTechnologie at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Bentley MicroStation or CoreTechnologie?
Bentley MicroStation starts at $2284/year and CoreTechnologie at On request.
Does Bentley MicroStation or CoreTechnologie run on more platforms?
Bentley MicroStation runs on Windows. CoreTechnologie runs on Windows, Linux.
What is Bentley MicroStation best used for?
Bentley MicroStation is most often used for a civil consultancy bidding on state dot or national highways work that mandates dgn deliverables and issues a microstation workspace, a rail or utility owner-operator maintaining decades of legacy dgn drawings that would lose data in a dwg round trip, an engineering firm standardising on openroads or openbuildings, which require the microstation platform underneath, a survey or asset team draping design geometry over point clouds and reality meshes for existing-conditions work. Of those, a civil consultancy bidding on state dot or national highways work that mandates dgn deliverables and issues a microstation workspace and a rail or utility owner-operator maintaining decades of legacy dgn drawings that would lose data in a dwg round trip are not what CoreTechnologie is typically brought in for.
What can Bentley MicroStation do that CoreTechnologie cannot?
Bentley MicroStation covers DGN modelling, DWG editing, Reality modelling, Parametric components. CoreTechnologie covers Native CAD conversion, Automatic geometry healing, Feature recognition, Simplification and defeaturing.

Answered from the vendors’ own pages

Bentley MicroStation: Can MicroStation open and save DWG files?

Yes, it edits DWG natively rather than importing it. Fidelity is good but not perfect on complex dynamic blocks and some annotation styles, so a DWG-mandated deliverable is still safer produced in AutoCAD.

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.

Bentley MicroStation: Is there still a perpetual licence?

Yes, Bentley still sells perpetual licences alongside term and Virtuoso subscriptions, but a perpetual licence needs an annual SELECT subscription to receive updates and support, so it is not a one-off cost.

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.

Bentley MicroStation: Do I need MicroStation if I have OpenRoads Designer?

No. The Open products include the MicroStation platform, so buying both separately is duplicate spend.

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.

Bentley MicroStation: What is a Bentley Key?

A prepaid token bundled with a Virtuoso subscription that you redeem for training, mentoring or consulting hours. Unused keys are a real cost if nobody in the team books the sessions.

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.
