MotionView Toolbars
The MotionView toolbars provide you with quick access to some of the most commonly used panels and tools.
Entity Selector
The Entity Selector
Graphic Entity Attributes
Model files are composed of many different parts, or entities. MotionView allows you to change the display attributes of each entity in a graphic. Visual properties such as shading, color, and
mesh lines can be assigned using the Graphic Entity Attributes panel.
Run Solver
The Run Solver tool allows you to either run the current model or run an existing solver command file generated previously
by MotionView .
System/Assemby
The System/Assembly panel allows you to add new systems and assemblies to your model, modify attachments, and set
initial conditions and options for systems and assemblies.
Analysis
The System and Assembly panel allows you to new analyses to your model, modify attachments, set initial conditions
for analyses, and set analyses options.
Command Sets
The Command Sets panel allows you to create command sets for the solver-command file. The command sets for a model are
order dependent, since they define the contents of the solver command file.
Points
The Points tool allows you to add points to models and edit point coordinates.
Vectors
Use the Vectors tool to create and edit vectors.
Markers
Use the Markers tool to create coordinate systems and reference frames.
Methods of Orientation
Coordinate systems in MotionView can be oriented using a variety of methods.
Curves
Use the Splines tool to create and edit curves.
Deformable Curves
Use the Deformable Curves tool to create and edit deformable curves.
Spline3D
The Spline3D panel allows you to add and edit three dimensional spline data.
Surfaces
The Surfaces tool allows you to create surfaces for use with advanced joint entities.
Deformable Surfaces
Use the Deformable Surfaces tool to create and edit deformable surfaces. These entities can change shape during the simulation
and can be used with advanced joints and contacts.
Graphics
Use the Graphics tool to create and edit visualizations for entities during pre-processing and post-processing.
Create Graphics Edit Graphics
Box
There are three ways in which a box graphic (or cuboid) can be defined based on the location of the graphic reference
frame about which the graphic is being created. The dimensions for the graphic are also specified using this reference
frame.
CAD
Curve
A curve graphic is created by positioning a 3D curve entity (Cartesian or parametric curve) in a reference frame (marker).
The reference frame can be an explicit marker or can be implicitly defined using a body-point-orientation method.
Cylinder
Deformable Curve
Deformable Surface
Ellipsoid
File
The file graphic type is used when realistic shapes of the bodies of the mechanism are to be included in the model.
Graphic Systems
A graphic system entity acts similar to that of a general system entity - it is intended to be used as a container
for graphic entities, and it can be used repetitively. Like general systems, graphic systems can use attachments that
refer to entities that are external to the system - this allows you to use them repetitively by parameterizing the
body, point, etc. that are typically needed to define the graphics within the graphic system.

Modify the Visual Attributes of a Graphic
From the Graphics panel’s Visualization tab, you can modify the visual attributes of the graphic types.
Bodies
Use the Bodies tool to create and edit rigid, point mass, and deformable/flexible bodies.
Joints
Use the Joints tool to create and edit basic joints.
Advanced Joints
Use the Advanced Joints tool to create and edit a set of special constraints called higher pair joints. Typically, these are constraints
that involve a curve or surface on at least one of the two bodies.
Couplers
A Coupler entity defines an algebraic relationship between the degrees of freedom of two or three joints.
Gears
Use the Gears tool to create a gear entity to relate the motion of two joints.
Bushings
Use the Bushings tool to create bushings and edit their connectivity, properties, and orientation rules.
General Constraints
Use the General Constraints tool to create a generic expression based constraint.
Fields
Use the Fields tool to create a compliant connection between two bodies where stiffness or damping in one direction can be a function
of displacement in another direction
Spring Dampers
Use the Spring Dampers tool to edit the connectivity, properties, and initial conditions of springs and dampers.
Beams
Use the Beams to create beams and edit their connectivity, properties, and orientations.
Polybeams
Use the PolyBeams tool to create polybeams and edit their points and properties.
Motions
Use the Motions tool to create motions and to edit the initial conditions, displacements, velocities, and acceleration
of joints.
Forces
Use the Forces tool to create forces and to edit the orientation and properties of forces.
Modal Forces
The Modal Forces tool allows you to include a disturbed force on a flexible body that exists in the modal form in the flexible body
H3D.
Contacts
Use the Contacts tool to specify the attributes of a contact force between two bodies.
Outputs
Use the Outputs tool to create a result output request to the solver, which writes out the requested data for plotting
data.
Sensors
Use the Sensors tool to sense an event during simulation and to define a response to that event
Control State Equations
Use the State Equations tool to create and set control state equation data.
Templates
Use the Templates tool to create and edit blocks of text that contain data fields and programming instructions.
Forms
Use the Forms tool to edit general data entry forms.
Datasets
Use the DataSets tool to create and edit datasets comprised of object types, such as real, string, boolean, integer, and options.
Solver Variables
Use the Variables tool to create solver variables that can be used to create an algebraic expression of state variables, as well as
other solver variables. This can then be referenced in function expressions throughout the solver input file.
Solver Arrays
Use the Arrays tool to create solver arrays and set solver array data. Solver array types include X array, Y array, U array, IC
array, Plant Input array, and Plant Output array.
Solver Strings
Use the Strings tool to create a solver string and set solver string data. A solver string provides a string that can be accessed
within the model, for example, to pass into a user subroutine.
Control SISOs
Use the SISOs tool to set control SISO data. This data can be used to add additional states to the mechanical system being modeled.
Solver Differential Equations
Use the Diff Equations tool to set solver differential equations. These equations can be used to add additional states to the mechanical
system being modeled.
