MoI 3D, or Moment of Inspiration, is desktop CAD software from Triple Squid Software Design for designers and artists building accurate models. Its workflow uses Boolean operations and 2D profile curves, serving as a companion modeler for rendering and DCC projects. MoI exports n-gon meshes for 3D printing and supports polygon formats including OBJ, STL, 3DS, LWO, FBX and SKP. For CAD exchange, it handles 3DM, IGES, STEP and SAT curve or surface files. PDF and AI exports create flattened 2D drawings, while DXF can carry 2D drawings or 3D wireframe curves. Version 4 adds multicore opening for several CAD formats, GPU display caching for large files, and annotation objects for dimensions, leaders and text. Windows and macOS installers come with each license and one key works on either or both. A 90-day trial is available. MoI has no sculpting tools or render engine, and its NURBS focus means OBJ meshes cannot be read.

Who it is for

It suits designers and artists who need precise desktop modeling, CAD-format exchange or 3D-print exports. It is available for Windows and macOS users.

What is good

  • Exports n-gon meshes for 3D printing
  • Supports 3DM, IGES, STEP and SAT formats
  • One license key works on Windows and Mac
  • Version 4 adds annotation tools
