The short version

  • Each has a real cost: MicroSurvey CAD dWG compatibility is file-level, not feature-level, so Civil 3D corridors, pipe networks and other object-enabled entities do not arrive intact and collaboration with engineering consultants remains awkward; 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: MicroSurvey CAD covers Coordinate geometry, MoI (Moment of Inspiration) covers Direct NURBS modelling.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

MicroSurvey CAD

  • A boundary surveying practice that wants to reduce field data, adjust the traverse and write the legal description in one packagenot MoI (Moment of Inspiration)
  • A firm that refuses to pay an AutoCAD subscription but must deliver DWG files clients can opennot MoI (Moment of Inspiration)
  • A survey office standardised on Leica total stations that wants instrument data flowing in without a translation stepnot MoI (Moment of Inspiration)
  • A two-person practice with irregular workload that wants to own its software outright rather than lose access if it stops payingnot MoI (Moment of Inspiration)

MoI (Moment of Inspiration)

  • Converting CAD surfaces into clean quad meshes for a polygon or sculpting applicationnot MicroSurvey CAD
  • Modelling hard-surface concept designs where form matters and engineering documentation does notnot MicroSurvey CAD
  • Working on older or low-specification hardware that will not run mainstream CADnot MicroSurvey CAD
  • Buying a modelling tool outright rather than committing to a recurring CAD subscriptionnot MicroSurvey CAD

Where each one falls short

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

MicroSurvey CAD

  • DWG compatibility is file-level, not feature-level, so Civil 3D corridors, pipe networks and other object-enabled entities do not arrive intact and collaboration with engineering consultants remains awkward
  • Only one price is listed publicly, for the floating network licence, and the differences between the Standard, Premium and Ultimate editions are resolved through a reseller conversation rather than a published comparison
  • It is Windows only and the installed base is concentrated in North America, so support, training material and experienced staff are much harder to find elsewhere
  • IntelliCAD lags AutoCAD on newer drawing format features and on third party plug-in availability, so a firm depending on a specific AutoCAD add-in will not find an equivalent
  • MicroSurvey now sits inside Hexagon alongside Leica Geosystems, which means the product competes for investment with a much larger portfolio, and buyers of a perpetual licence should ask about the release cadence commitment before assuming years of updates

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

MicroSurvey CAD: Do I need AutoCAD to run it?

No. It is built on the IntelliCAD engine and reads and writes DWG natively without an Autodesk licence.

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.

MicroSurvey CAD: Is it a perpetual licence or a subscription?

Perpetual. The listed 2,945 US dollar licence includes one year of maintenance and support, after which maintenance is optional.

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

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

MicroSurvey CAD: Who owns MicroSurvey?

Hexagon, the same group that owns Leica Geosystems.

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.

MicroSurvey CAD: Will Civil 3D drawings open correctly?

The geometry will. Civil 3D object data such as corridors and pipe networks will not come through as editable objects.
