Short Answer
In the 3D viewer you navigate with the toolbar (orbit, pan, zoom, fit to view), select elements with a left-click, Ctrl/Shift-click or a selection rectangle, and right-click to open a menu with actions such as “Show selection only”. The icons give you properties, model browser, section plane, measuring, exploded view and more.
Navigating
- Orbit: Freely rotate the model around its axis.
- Pan: Move the view in parallel.
- Zoom: With the mouse wheel or the zoom tool; “Zoom window” draws a rectangle.
- Fit to view: Brings the whole model back into frame (key F).
Selecting elements
- Left-click: Select an element.
- Ctrl or Shift-click: Add or deselect individual elements.
- Ctrl + drag: Draw a selection rectangle over several elements.
- Esc: Clear the selection.
Tools & icons
- Properties (info): Shows all attributes of the selected element.
- Model browser: Browse the model structure by levels and components.
- Section plane: Cut along X, Y, Z or as a box.
- Measure: Measure distance, angle, area and coordinates.
- Exploded view: Pull components apart.
- Show rooms: Toggle room volumes on and off.
- Settings and full screen: Adjust the display or open the viewer in full screen.
Right-click menu
- Show selection only: Hides everything except the selection.
- Hide / show selection: Hidden or previously hidden elements.
- Section plane / clear section: Add or remove a section plane.
- Show entire building: Shows all elements again.
- On model elements additionally: Create group, move, remove.
Good to know
The restriction (e.g. “Show selection only”) stays active even if you change the selection, and is reset when you leave the page.
