Alternatives to Rhinoceros
Create and edit precise freeform 3D models for design and fabrication. The listings below can replace it for an important use case. Each note says what changes if you switch.
The original
Rhinoceros
Create and edit precise freeform 3D models for design and fabrication.
Replacements
Listings that take over the same core job as Rhinoceros.
MoI 3D
Create precise curves and surfaces with a streamlined NURBS modeler.
MoI 3D is a streamlined paid NURBS modeler for Windows and macOS with pen-tablet support, but it lacks the broad plugin ecosystem Rhinoceros offers.
Plasticity
Model solid and surface forms with CAD tools aimed at visual design.
Plasticity focuses on artistic hard-surface modeling with direct shape manipulation and adds Linux support, though it is paid and format support depends on the edition.
Shapr3D
Touch-first parametric CAD app originally built for iPad, now on desktop.
Shapr3D moves to touch and stylus-first parametric CAD on iPad, Windows and macOS with a limited free tier, rather than freeform NURBS surface modelling.

SolidWorks
Industry-standard parametric CAD software for 3D design and product development.
Blender
The free 3D creation suite: modelling, sculpting, rigging, animation, simulation, rendering, compositing and video editing.
KeyShot
Commercial real-time 3D rendering software for producing product visuals from CAD data.
Twinmotion
A real-time 3D visualization tool from Epic Games for architecture, products and design presentations.
