The Solidly window
Solidly is a single-window application. Every open file lives in that window, and the sidebar is how you move between them. Opening several models from the Finder at once adds them to the existing window.
The sidebar
The left column has a mode picker at the top, a search field beneath it, and a list below that.
| Mode | Contents | Available for |
|---|---|---|
| Models | Every file open in the session, with expandable rows for the child assets of a composite file | Every format |
| Hierarchy | The scene graph of the selected model, as a tree of nodes | Every format with a scene graph |
| Layers | The tree of files a USD stage composes from | USD only |
Press Tab to switch between Models and Hierarchy, and Esc to return to Models.
The + button beside the mode picker changes with the mode. In Models it opens a file. In Hierarchy it offers a menu of nodes to add, along with Combine glTF Model…, for the formats whose hierarchy Solidly can edit. It is inert in Layers mode, which is read-only.
Search filters the active list, and each mode keeps its own search text.
The viewport
The centre of the window draws the selected model. Alongside it, the viewport can draw a ground grid, a navigation cube, the selection outline, and the transform gizmo. The grid and the navigation cube are drawn while the sidebar is in Hierarchy or Layers mode. Clicking a face of the cube moves the camera to the matching orthogonal view.
The inspector
The right column describes whatever is selected. Its tab strip adapts to the format of the selected model.
| Tab | Describes |
|---|---|
| Info | The file as a whole: format, counts, scenes, variants, cameras, extensions, and authoring metadata |
| Node | The selected node, prim, or geometry partition |
| Materials | The shared texture pool and every material in the file |
| Resources | The file's own resource arrays, in the vocabulary of its format |
| Render | How the viewport is drawing this model right now |
The toolbar
The toolbar carries the transform tool cluster, Move and Scale, on the left, and Compress Model, Photo Mode, and Inspect on the right. The transform tools appear while a hierarchy node can be selected. Compress Model is enabled for glTF and GLB models.
The animation player
Models that carry animation get a control floating over the bottom of the viewport, holding a clip picker, play and pause, a loop toggle, a reset button, a timeline, and a playback speed picker. Press ⇧H to show or hide it. See Animation playback.
Notifications
Progress and status are reported in a single notification area. Long operations, such as a compression export, appear as a progress chip that stays until the work finishes. Confirmations, warnings, and errors appear as messages that clear themselves, and how long they stay is set in Settings ▸ General ▸ Notifications. Messages waiting on a decision stay until answered.
