CAD Viewer Features

Load this only when a task needs Viewer file-support details or UI control guidance.

Supported Files

.step, .stp: STEP/STP review through hidden GLB sidecars; supports assembly trees, part hide/show, inspect/focus, face/edge/vertex/part selection, copied #... CAD references, display modes, clip planes, and optional STEP module parameters/animations when a sidecar module exists.
.stl, .3mf, .glb: mesh viewing with orbit/pan/zoom, screenshots, appearance controls, and solid/wireframe display where available.
.dxf: read-only flat-pattern viewing, plus plate thickness and bend direction/angle controls when bend preview data is available.
.gcode: diagnostic toolpath preview; shows layer-colored extrusion ribbons, optional travel moves, visible-layer and detail controls, feature markers, movement stats, bounds, and parser warnings. It does not reslice, simulate firmware, or replace G-code validation.
.urdf: robot link/mesh viewing with movable joint sliders, reset pose, and copied joint values.
.srdf: linked-URDF viewing with planning groups, group-state presets, joint controls, and optional MoveIt2 IK/planning controls.
.sdf: SDF model/world viewing with metadata, counts, warnings, and joint controls when available.

Navigation: left-drag to orbit, right/middle-drag to pan, wheel or pinch to zoom, and Arrow/WASD keys to orbit. Use the view sphere for top/bottom/front/back/left/right views; click its center for the default isometric view.
File browser: toggle the left CAD Viewer sidebar, search files/ids/paths, expand folders, select entries, or switch files from the breadcrumb menus.
Floating toolbar: Select copies STEP topology references, Draw opens annotation tools, Select Pose appears for robot target picking when available, Open orbit preview starts an auto-rotating preview, and the copy/download buttons capture screenshots.
Drawing tools: freehand, line, arrow, expand, rectangle, circle, fill, erase, undo, redo, and clear.
File sheet: open the right sheet for file-specific controls such as STEP tree/parameters, G-code layers/detail/travel, DXF thickness/bends, URDF/SRDF/SDF joints and metadata, plus display and appearance controls.
Display/appearance: use the file sheet and theme menu for solid/wireframe/x-ray modes, STEP clipping, an independent Explode toggle for animated vertical STEP disassembly, surface colors, edge visibility/detail, highlight styling, backdrop, floor/grid, lighting, theme presets, and color mode.
