Motions
Use the Motions tool to create motions and to edit the initial conditions, displacements, velocities, and acceleration of joints.
Create Motions
Edit Motions
A motion can be a displacement, velocity, or acceleration and can be applied to some joint types or between markers.
Define the Connectivity of Motions
Option | Description |
---|---|
Displacement | Requires no initial conditions |
Velocity | Requires an initial displacement |
Acceleration | Requires an initial displacement and an initial velocity |
- Select the axis to define the translational or rotational motion.
- Select an option from the Properties drop-down menu.
- Click the Marker 1 and Marker 2 collectors to select the first and second markers to which to the motion is applied.
Define the Properties of Motions
From the Properties tab, you can define the magnitude of a motion either as a constant value or as a non-linear value using a 2D curve, 3D spline, or expressions.
Define the Initial Conditions of Motions
Use User-Defined Properties for a Motion
If desired, define the motion using the User-Defined tab, which will allow you to specify the properties of the motion using user subroutines.
