Supported file formats
Solidly opens glTF, GLB, USD, USDA, USDC, USDZ, FBX, OBJ, STL, and PLY files. Solidly supports loading single assets or entire folders of assets.
See the format referenceThe everyday workof 3D files
Inspection, scene and material editing, material reconstruction, and image rendering run in one native Mac application, across every format Solidly opens.
Inspection
View the full contents of a 3D file. Scene graph, node transforms, meshes and their vertex attributes, materials and texture bindings, cameras, lights, animation, and metadata. All of it displayed in a user-friendly format.
Editing and repair
Fix what’s wrong with a 3D file. Rename and reparent nodes, correct transforms, rebind textures, edit materials and metadata, generate a UV atlas for a mesh missing one, and much more. All savable back in the file’s own format.
Photo Mode
Turn a 3D file into an image worth showing. Camera position, field of view, focus and aperture, lighting, and background. All rendered in a selectable resolution as a PNG, JPEG, HEIC, TIFF, or WebP.
Material reconstruction
FBX and OBJ files often arrive as bare geometry with their textures loose in the folder. Solidly reads those images, works out what each one is, and rebuilds the materials onto the meshes that use them.
Capabilities by format
Solidly can open and inspect every format listed below. Editing and saving vary from format to format, depending on what the format is able to represent and on what Solidly supports.

Questions & Answers
Is Solidly a 3D modeling application?
Solidly is not a modeling application. It provides no vertex editing, sculpting, retopology, rigging, or animation authoring. It operates on files that already exist, opening them, reporting what they contain, correcting errors in them, and rendering images from them.
Can Solidly convert a file from one format to another?
Solidly saves a file in the format it was opened from and does not convert between formats. A file opened as an FBX is written back as an FBX.
Can Solidly open .blend, Maya, or CAD files such as STEP?
Solidly opens the interchange formats listed above. Application project files, such as those written by Blender and Maya, and CAD files, which describe surfaces and solids rather than polygon meshes, must be exported to one of the supported formats before Solidly can open them.
Is there a Windows or Linux version?
Solidly is available for macOS only. It is written in SwiftUI over a Metal renderer and depends on macOS frameworks, and no Windows or Linux build exists.
Does Solidly run on iPad or iPhone?
Solidly is a Mac application. There is no iPadOS or iOS version.
Which Macs can run Solidly?
Solidly runs on Apple Silicon Macs with macOS 26 Tahoe or later. It is built for Apple Silicon only, and Intel Macs are not supported.
Do my files leave my Mac?
Models are opened, edited, and rendered locally, and material reconstruction runs on the device. Servers are used only to sign in to an account that holds a purchase.
