Camera and views
Orbit, pan and zoom with the mouse, where the camera pivots, zooming to the selection, and jumping to standard views with the ViewCube.
The camera behaves the same way in every 3D editor in Atrium. Atrium picks the pivot point from your selection and the pointer position, so you always orbit around what you're looking at. The ViewCube in the corner of the screen takes you to standard views quickly.
Mouse controls
You move around the model with the right mouse button, just like in Rhino:
| Mouse | Action |
|---|---|
| Right-drag | Orbit |
| Shift + right-drag | Pan |
| Ctrl + right-drag | Zoom |
| Mouse wheel | Zoom at the cursor |
- In a 2D view (Top, Front, and so on), a plain right-drag pans.
- You can change the orbit and pan modifiers in Settings.
- While you orbit, the pointer becomes a sphere with a ring; while you pan, it becomes a hand.
Pivot point
The rule is the same as in Shapr3D and Onshape, and it's identical in every 3D editor:
| Situation | Pivot point |
|---|---|
| Something is selected | The center of the selection, if all of it is on screen. If you've zoomed in on part of it and it doesn't fit on screen, the point under the pointer. |
| The pointer is over a part | The center of that part (or assembly), if all of it is on screen; otherwise, the point under the pointer. |
| The pointer is over empty space | The center of the model, if the whole model is on screen; otherwise, the center of the screen. |
Tip
The camera never jumps to the origin unexpectedly.
Zoom
- Scroll the mouse wheel to zoom at the cursor, or Ctrl + right-drag.
- Press Z to zoom to the selection. If nothing is selected, it shows the whole scene. This key works in every editor, including the plan.
- When you select something, a Zoom badge also appears next to it.
- The Zoom all button on the ViewCube shows the whole scene.
While you zoom, the pointer becomes a magnifier.
ViewCube
The ViewCube is a small cube that shows the camera's current orientation and takes you to standard views.
Position
The ViewCube sits at the top right of the screen, next to whichever panel is open on the right (Properties or Library). When that panel is closed, the ViewCube moves to the right edge of the screen, below the document buttons.
Using the ViewCube
| Action | Result |
|---|---|
| Click a face | The camera moves smoothly to that view. Faces are 2D views (Top, Front, and so on). |
| Click an edge or corner | The camera moves to a 3D view from that side. |
| Arrows around the cube | Orbit in 45° steps, like regular orbiting; the horizon stays level. |
| Curved arrows | Rotate the view itself by 90°. |
| Home | Isometric view |
| Zoom all | Show the whole scene |
If you click or scroll while the camera is moving, it jumps straight to its destination.
Note
In 2D views (Top, Front, and so on), Planar snap is always on. See Snaps and SmartTrack.
