Focus → rotate → zoom

1. Click a part of the model. The camera gently looks towards it. This point becomes the centre for camera rotation. Transparent areas let you click through to objects behind them.
2. Hold Option (Mac) or Alt, then drag. Move the mouse while holding the left button to rotate the camera around the focused point.
3. Scroll to zoom. Use the wheel or trackpad over the area you want to inspect. Scroll up to move closer; scroll down to move away.
4. Right-drag to pan. Move the view sideways or up/down. Click another part whenever you want a new focus point.

Lighting: hold Ctrl and left-drag horizontally to turn the lights around the model. The model and camera stay still.

Reset view / Esc: return to the saved opening camera, zoom and lighting. Double-click: move closer to the clicked part.

Rotate: start/stop automatic camera rotation. Interacting with the model stops it. Fullscreen: enter/leave browser fullscreen. Projects: open another design. Click Help again to close this guide.

Automatic alpha: solid textures render opaque; cutout edges use an automatic threshold. Glass, material opacity and soft shadows keep their transparency. Original files are preserved.
