Sphere mode, camera mode

Sphere mode

In Sphere mode (default setting), you guide the camera on an imaginary sphere around the target point located at the center of the sphere by selecting the mouse button while dragging. In other words, the position of the camera (the eye point, observer) changes; the target point is static. The target point should be as near to the object being animated as possible.

Sphere mode is especially useful if you want to rapidly view an object from all sides.

Camera mode is better for viewing objects from the inside.. Select the Ctrl key.

The following movements are possible:

Turn camera about object on the surface of an imaginary sphere:	Select and hold the left mouse button. Cursor shape:
Move the camera laterally, up, or down:	Select and hold the middle mouse button. Cursor shape:
Move camera toward or away from the object	Select and hold the right mouse button. Alternative: Use the wheel. Cursor shape:

When rotating the camera around the object, set the position of the rotation axis as follows:

If you click outside the model, the camera is rotated around the axis of the scene, i.e. around the entire model.
When you click in the model, a coordinate system is displayed at the clicked point and the camera is rotated around this point. The Z axis of the superimposed coordinate cross corresponds to the rotation axis of the scene. This makes it easier to move around indoors in particular: For example, you can click on a table in the middle of the room and then rotate the camera around it.

Camera Mode

In Camera mode (select and hold the Ctrl key), you control the camera's viewing direction by selecting and holding the mouse button. In other words, the position of the camera (the eye point) does not change; the viewing direction (the target point) changes. This Camera mode is particularly useful if you want to view a building from the inside. For example, if you want to "walk" through corridors, walk up stairs.

Sphere mode is better for viewing an object from all sides. Release the Ctrl key.

Note: It is the observer that moves, not the object!

The following movements are possible:

Rotate camera:	Ctrl+left mouse button. Cursor shape:
Move the camera laterally, up, or down:	Select and hold the middle mouse button. Cursor shape:
Move camera toward or away from the object	Ctrl+right mouse button. Alternative: Ctrl+mouse wheel. Cursor shape:

Tip: As soon as the cursor reaches the edge of the screen, it appears again on the opposite side.

Note: In sphere mode, the target point of the camera is static; this mode is particularly useful for viewing a building from all sides. To facilitate intuitive navigation within buildings, you can enter a value for the Minimum offset for navigation mode and mouse wheel option. Allplan will automatically switch to camera mode as soon as the offset is less than this value. The default setting is 1 m. You can find this option in the Options - Desktop environment - Mouse and crosshairs - Mouse area.

Note: You can invert the effect of the mouse movement on the model using the Reverse direction in navigation mode option in the Options - Desktop environment - Mouse and crosshairs - Mouse.
