Changes Viewport to Multi-Camera 2D View
Opens a context menu to select pre-defined 3D views.
Opens a context menu to select a camera to set as the 3D Viewpoint.

Enable/Disable the follow selected marker feature, skeleton, or rigid body in the perspective view during both capture and playback.
Zooms into selected markers or assets to fit the perspective view pane.
Zooms into existing assets to fit the perspective view pane.
Select Tool. Using this tool, you can select objects that are in the 3D view pane.
Translate Tool.* Using this tool, you can select a group of reconstruct markers and apply translation along the global x-y-z axis. When the Edit Skeleton 
is enabled, this tool can also be used to translate skeleton bones along x, y, z of the segment axis or the global axis. This feature is supported for post-processing of a recorded 3D data only. When the change is made, the segment hierarchy will be modified and reflected on exported skeleton bone data but the marker locations will remain the same.
Rotate Tool.* Using this tool, you can select a group of reconstructed markers and apply rotations about the global x-y-z axis. When the Edit Skeleton is enabled, this tool can also be used to rotate skeleton bones along x, y, z of the segment axis or the global axis. This feature is supported for post-processing of a recorded 3D data only. When the change is made, the segment hierarchy will be modified and reflected on exported skeleton bone data but the marker locations will remain the same
Scale Tool.* Using this tool, you can select a group of reconstructed markers and re-scale the displacement between each marker along the global x-y-z axis. When the Edit Skeleton is enabled, this tool can also be used to rescale length of skeleton segments. This feature is supported for post-processing of a recorded 3D data only. When the change is made, the segment hierarchy will be modified and reflected on exported skeleton bone data but the marker locations will remain the same
Assign Skeleton Markers Tool.* This tool allows you to associate markers to a skeleton segment by selecting them together. For more information: Skeleton Tracking page
Axis.* This determines whether the global coordinate axis or the local segment axis would be used When applying translation, rotation, or scaling tools to recorded 3D data.
Local Axis (LCL): The changes will be applied in respect to the local coordinate axis of the selected asset.
Global Axis (GCL): The changes will be applied in respect to the global coordinate axis of the capture volume.
Enable/disable Marker Selection.
Enable/disable Camera Selection.

Enable/disable Skeleton Selection.*
Enable Assigned Marker Selection.* When this feature is enabled, you can select on expected marker positions (transparent) of skeleton and rigid body assets.
For the skeleton assets, this can be used to remove assigned markers from corresponding definitions. For more information: Skeleton Tracking page.
Opens a context menu to enable or disable visual aids for the perspective view, which includes the following:
Assigned Markers: Show/Hide expected, or assigned, marker positions that allow auto-labeling of markers for tracking assets.
Marker Count: Show/Hide reconstructed and selected marker counts at the bottom-right corner of the view.
Marker Labels: Show/Hide marker labels for the selected markers.
Marker Label Colors: Show/Hide unique marker color for better distinguishing multiple marker labels within an asset.
Marker Sticks: Show/Hide marker sticks for skeleton assets.
Marker History: Show/Hide marker trajectory history trail.
Two Marker Distance: Show/Hide marker distance information that appear when two markers are selected from the 3D view.
Three Marker Angle: Show/Hide three marker angle that appears when three markers are selected from the 3D view.
Tracked Rays: Show/Hide Tracked Rays from the view. Tracked rays are the marker centroid rays (available only in 2D data) from each camera that contributes to the 3D reconstruction.
Untracked Rays: Show/Hide Untracked Rays from the view. Untracked Rays are the marker centroid rays (available only in 2D data) that are seen by each camera but does not contribute to the 3D reconstructions because the reconstruction requirements, usually the ray count, are not met.
Capture Volume: Show/Hide virtual scope of the tracking capture volume based on the camera calibration.
Coordinate Axis: Show/Hide global coordinate axis at the left-bottom corner of the 3D view.
Camera Labels: Show/Hide camera labels from the 3D view.
Toggle to show/hide markers from the perspective view.
Toggle to show/hide skeletons from the perspective view.*
Toggle to show/hide rigid bodies from the perspective view.
Edit Skeleton*. When this feature is enabled, users can translate, rotate, and rescale individual bone segments of skeleton assets within a recorded 3D Take.
Symmetrical bone length and orientation* When this feature is enabled, any modifications on bone lengths and orientations are applied symmetrically on both left and right side of a skeleton.
Two Marker Distance
In the 3D perspective view pane, you can quickly check 3D distance between a set of two markers. First of all, make sure to enable the Two Marker Distance feature under the visual aids, and select two markers to measure the distance from. Then, the corresponding displacement (in mm) between two markers will be displayed on the view port.
Three Marker Angle
Likewise, an angle formed by three markers can also be examined. Make sure the Three Marker Angle display feature is enabled under the visual aids. When this feature is enabled, the respective angle (in degrees) will be measured and displayed over the viewport when a set of three marker is selected from the scene. Note that the selection order will determine the vertex point when measuring the angle.
Camera Preview

Create (Select at least 3 markers): Creates a rigid body asset from selected markers. At least 3 markers must be selected in order to create a rigid body. (default hotkey: CTRL + T)
Add Selected Markers to Rigid Body: Adds a selected marker to a rigid body asset. To use this feature, a marker and a rigid body must be selected together.
Remove Selected Markers from Rigid Body: Removes a selected marker from a rigid body asset. To use this feature, a rigid body marker and an associated rigid body must be selected together.
Set Pivot Point to Selected Marker: Sets the pivot point of a rigid body asset on a selected marker. To use this feature, a rigid body and a marker must be selected together.

Reset Pivot: Repositions the rigid body pivot point at the center of a rigid body.
Update Pivot to Spherical Placement: This feature assumes that the markers are placed on a spherical object, and repositions the rigid body pivot point right at its center.
Remove: Removes a rigid body.
Remove Selected Markers From Rigid Body: Removes the selected rigid body marker position from the rigid body asset definition. In order to do this, Enable Skeleton Assigned Marker Selection
, must be enabled to select the rigid body marker definition.

Show Last Good Pose: When this feature is enabled, the skeleton asset will keep its last good pose when the tracking is lost. More specifically, enabling this feature prevents skeleton solver from trying to solve bone segments with unlabeled markers, and last good pose will be retained for the untracked segments; preventing erratic movements when tracking of a skeleton is lost.
Remove All Skeletons: Removes all skeleton assets from a capture.
Remove Selected Skeletons: Removes selected skeleton assets from a capture.
Remove Selected Markers from Skeleton: Removes selected skeleton marker from the skeleton asset definition. In order to do this, Enable Skeleton Assigned Marker Selection
, must be enabled to select the skeleton marker definitions.

Zero (all): Zeroes, or tares, all selected force plates.
ReSynch (all): For triggered synchronization protocols, (e.g. force plates that syncs using the record trigger), this feature re-synchronizes force plates with the camera system. This will remove any sync offsets that may have increased gradually since the trigger.
