The solidly command

Solidly ships a standalone solidly executable that does two things: it opens a model in the application, and it renders images using the same renderer the application uses.

Installing

The signed executable is inside the application bundle at Solidly.app/Contents/Helpers/solidly. Link it into a directory on your PATH to make it available under that name:

sudo ln -sf "/Applications/Solidly.app/Contents/Helpers/solidly" /usr/local/bin/solidly

Shape

solidly <model>
solidly render <file-or-folder> [options]

A bare model path opens that file in Solidly, exactly as opening it from the Finder would.

Help and version

solidly --help
solidly render --help
solidly --version

What it accepts

<file-or-folder> may be:

• a single .gltf, .glb, .fbx, .obj, .stl, .ply, .usd, .usda, .usdc, or .usdz file
• a folder containing a model and its sibling files
• a folder containing many models
• a folder of subfolders containing models

Folder scanning follows the same rules as the application, described in Opening files and folders.

Rendering

solidly render ~/Models --output ~/Renders --preset front --resolution 3840x2160

Every render setting is an ordinary command line option, so a complete invocation can be kept in a shell script. solidly render is the full option reference.

The renderer enforces the same import memory limit the application does. A model that would exceed it is reported as a failure for that file, and the run continues with the next one.
