AC3D vs Meshy

AC3D is desktop 3D design software for creating models, prototypes, virtual reality simulations, and data visualisations. It runs on Linux, macOS, and Windows, with animation tools, rendering, and 3D print export. Modeling features include subdivision surfaces, UV mapping, 2D and 3D text, boolean operations, polygon reduction, and object hierarchy. It imports and exports formats including 3D Studio, Collada, DirectX, DXF, OBJ, STL, VRML, and X3D. A software development kit and plugin interface allow additions such as file formats and other functionality. An optional plugin adds animation capability for X-Plane models on Windows, Mac, and Linux. AC3D also lists support for 3Dconnexion mice on Windows. A 14-day trial is available. The maker lists one-time prices of $99.00 USD for Home / Student and $99.00 USD for Commercial / Group (5 users/seats); other listed seats have different prices. Purchases are non-refundable, and the software is delivered by download with the license emailed after purchase.

Meshy creates 3D assets from text, images, or creative concepts for users to preview, edit, and export. Text-to-3D generates textured models from written descriptions, while Image-to-3D works from photos, sketches, or concept art. It can auto-rig humanoid and quadruped characters and offers more than 600 motion presets. For 3D printing, Meshy says its models are watertight and manifold; its printability check scans exports and can repair some edge cases. Integrations include Blender, Unity, Unreal Engine, Godot, Roblox Studio, Bambu Studio, OrcaSlicer, and Creality Print, along with a REST API and MCP server. The Android and iOS app syncs with the web app and exports formats including STL, GLB, FBX, OBJ, USDZ, and 3MF. The web app has a 100 MB upload limit for AI texturing and accepts one model at a time. Meshy has a free plan; Pro starts at $20 a month. Free-plan assets use CC BY 4.0 and require attribution for commercial use.
