The short version

  • Only FreeCAD has a free tier, so it costs nothing to try first.
  • Each has a real cost: Carlson Software the perpetual licence is a larger upfront cost than a first-year subscription, which is harder to approve for a practice with tight cash flow even though it is cheaper over five years.; FreeCAD no pricing published; product is completely free and open-source
  • They diverge on capability: Carlson Software covers Survey data reduction, FreeCAD covers Parametric modeling.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Carlson Software

  • The perpetual licence is a larger upfront cost than a first-year subscription, which is harder to approve for a practice with tight cash flow even though it is cheaper over five years.
  • It is Windows only, so a practice on macOS has to run virtualisation, and there is no browser or mobile design client.
  • Carlson is a smaller ecosystem than Autodesk, so hiring staff who already know it is harder and training time is a real cost when a new surveyor joins.
  • Skipping maintenance saves money but leaves you on an old release, and when a client eventually sends a file from a much newer version the compatibility gap becomes your problem to solve.
  • Pricing is largely sold through resellers with figures varying by dealer and region, so the published $4,450 Civil Suite price is a reference point rather than a firm quote.

FreeCAD

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