The editor has five main regions: the top bar, the left sidebar, the canvas with its viewer toolbars, the bottom toolbar, and the floating panels that appear as you work.
Overview of the Pascal editor interface

Top bar

From left to right:
  • Pascal logo — click to go back to your projects; hovering opens a project sidebar for quick switching.
  • Project title — click it to rename the project inline.
  • Edit / Studio toggle — switches the whole workspace between building (Edit) and generating rendered images (Studio). The Studio button shows your credit balance. See Studio renders.
  • Feedback — send feedback to the Pascal team.
  • Radio Pascal — background music while you build.
  • Settings — project settings, including what’s visible to the public.
  • Preview — view your scene without editing chrome.
  • Walkthrough — enter a first-person walk through your building.
  • Version control — shows the current version; click Save to pin a new version, or open the dropdown for the version history and what’s live.
  • Private / Public — the project’s visibility, with a copy-link button for the viewer. See Sharing your work.
  • Profile — your account menu.
An icon rail on the far left switches the sidebar between tabs. Click the active tab’s icon again to collapse the sidebar, and drag its right edge to resize it.
  • Build — structural elements: Wall, Fence, Slab, Ceiling, Roof, Stairs, Elevator, Door, Window, Column, Spawn Point, plus Painting (materials), MEP (ducts and pipes), and Pre-built rooms. Clicking a tile arms its tool and shows its presets below, filtered by source (All / Pascal / Mine / Community).
  • By room — the catalog filtered by room type (kitchen, bedroom, bathroom, …), so you can furnish one room at a time.
  • Items — the furniture and object catalog, organized by category. See Finding items.
  • Search — search everything in the catalog at once.
  • Scene — the scene tree: buildings, levels, and everything on them.
  • Files — files attached to the project, such as uploaded scans and guide images.
  • Chat — the AI assistant. It opens by default in a fresh session; see AI assistant.
In Studio mode the rail is replaced by a single Generate tab.

Viewer toolbars

Two small toolbars float over the top of the canvas. Top left — view mode. A segmented 3D / 2D / Split control. 2D is a flat floor plan of the active level; Split shows both side by side. Drawing tools work in both views. Top right — display controls.
  • Levels — cycles how floors stack: Stack, Exploded, Solo.
  • Walls — cycles wall height rendering: Cutaway, Full height, Low.
  • Display — a menu gathering Shadows (On/Off), Camera (Perspective/Orthographic), Units (Metric/Imperial), Render (Solid/Rendered), Materials (Colored/Monochrome), Edges (Off/Soft/Strong), and scene Theme.

Level selector

A floating panel at the top left of the canvas lists your levels. Click a level to make it active, and use Add level above / Add level below to grow the building. Each level’s menu supports rename, duplicate, and delete, and you can drag levels to reorder them. Cmd/Ctrl + ↑ / Cmd/Ctrl + ↓ switch levels from the keyboard. See Floors & levels.

Bottom toolbar

Centered at the bottom of the canvas:
  • Select (V) — the default mode: click to select, drag to move.
  • Zone (Z) — draw named zones (rooms/areas) on the floor plan.
  • Delete (X) — click elements to remove them.
  • References — toggles uploaded scans and guide images on the current level, with per-item opacity, visibility, and upload controls.
  • Orbit Left, Orbit Right, Top View — camera buttons.

Inspector and helpers

  • Inspector — selecting an element opens a floating panel at the top right of the canvas with its properties (dimensions, options, materials). Drag its header to move it; click the header to collapse it to a title bar.
  • Contextual hints — while a tool is active, a hint strip shows the keys that matter right now (snapping mode, rotation, selection modifiers).
  • Command palette — press Cmd/Ctrl + K to search commands: tools, level actions, view toggles, snapshot, undo/redo, and more.

Undo

Cmd/Ctrl + Z undoes, Cmd/Ctrl + Shift + Z redoes — for building, placing, painting, and deleting alike. The full list of shortcuts is on the keyboard shortcuts page.
