The short version

  • Only FreeCAD has a free tier, so it costs nothing to try first.
  • 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.; FreeCAD no pricing published; product is completely free and open-source
  • They diverge on capability: Bentley MicroStation covers DGN modelling, FreeCAD covers Parametric modeling.
  • 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.

FreeCAD

  • No pricing published; product is completely free and open-source
  • Donations are optional and voluntary for project support

Questions people ask

Is Bentley MicroStation or FreeCAD better?
Neither clearly leads. Bentley MicroStation starts at $2284/year and FreeCAD at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Bentley MicroStation or FreeCAD?
FreeCAD has a free tier; the other does not. Paid plans start at $2284/year for Bentley MicroStation and Free for FreeCAD.
Does Bentley MicroStation or FreeCAD run on more platforms?
Bentley MicroStation runs on Windows. FreeCAD runs on Windows, macOS, Linux.
Can I use FreeCAD for free?
Yes. FreeCAD has a free tier, so you can try it without paying. Bentley MicroStation starts at $2284/year.
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 FreeCAD is typically brought in for.
What can Bentley MicroStation do that FreeCAD cannot?
Bentley MicroStation covers DGN modelling, DWG editing, Reality modelling, Parametric components. FreeCAD covers Parametric modeling, Part design, Assembly, Drafting.

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.

FreeCAD: How much does FreeCAD cost?

FreeCAD is completely free with no licensing fees, vendor lock-in, sign-up requirements, paywalls, or restrictions. The software is open-source and available for anyone to use and adapt.

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.

FreeCAD: Does FreeCAD offer optional support or sponsorship?

FreeCAD accepts voluntary donations to support the project. Sponsorship tiers range from $1 per month (Normal Sponsor) to $200 per month (Gold Sponsor), with different visibility levels. One-time donations of any amount are also accepted.

Source
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.

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.
