The short version

  • 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.; MoI (Moment of Inspiration) it is developed by one person, so releases are years apart and there is no support organisation to escalate to when something blocks your work.
  • They diverge on capability: Carlson Software covers Survey data reduction, MoI (Moment of Inspiration) covers Direct NURBS modelling.
  • 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.

MoI (Moment of Inspiration)

  • It is developed by one person, so releases are years apart and there is no support organisation to escalate to when something blocks your work.
  • There is no parametric history and no assembly structure, so a late design change means remodelling rather than editing a feature.
  • It produces no dimensioned drawings or manufacturing documentation, so anything heading for production needs a second package for the paperwork.
  • Exchange is limited to surface formats such as STEP and IGES with no native interoperability with mainstream MCAD systems, so it sits at the edge of an engineering pipeline rather than inside it.
  • Each major version is a fresh purchase, and the long gaps between versions mean a fix or a feature you need can be several years away with no interim release.

Answered from the vendors’ own pages

Carlson Software: Is Carlson a perpetual licence?

Yes. You buy it once and it keeps running. Annual maintenance at roughly ten per cent is optional and only affects updates and support.

MoI (Moment of Inspiration): Is it a subscription?

No. It is bought outright per major version, and each new major version is a separate paid upgrade.

Carlson Software: Do I need AutoCAD as well?

No. An IntelliCAD engine is included. You can alternatively run Carlson on top of AutoCAD if your practice already licenses it.

MoI (Moment of Inspiration): Can it replace Rhino?

For direct form modelling, often yes. For anything needing Grasshopper, drawings, plugins or engineering interoperability, no.

Carlson Software: Does Carlson field software work with other brands of instrument?

Yes. SurvCE supports total stations and GNSS receivers from several manufacturers, which is one of the main reasons firms choose it.

MoI (Moment of Inspiration): Why do 3D artists use it alongside other tools?

Its NURBS to polygon conversion produces cleaner meshes than most CAD exporters, which saves retopology work downstream.

Carlson Software: What does the Civil Suite include?

Survey, Civil, Hydrology and GIS, listed at $4,450.
