The short version

  • Only Shapr3D has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; Shapr3D the free Basic plan is limited to 2 projects
  • They diverge on capability: MoI (Moment of Inspiration) covers Direct NURBS modelling, Shapr3D covers Direct 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.

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.

Shapr3D

  • The free Basic plan is limited to 2 projects
  • Free plan exports only basic resolution 3MF and STL, so no STEP or IGES output
  • Free plan caps generative renders at 3 per day; Pro raises this to 50 per day and only Enterprise is unlimited
  • Importing SLDPRT and SLDASM SolidWorks files requires Pro
  • Importing NX, JT, CREO, Solid Edge and Rhino files requires Enterprise
  • Exporting ACIS, FBX, Parasolid and PRC requires Enterprise
  • On premises and single tenant data storage is Enterprise only
  • Enterprise pricing is by quote with no published rate
