About the Dynamic Simulation Browser

The Dynamic Simulation browser shows the elements of the mechanism. It provides access to each of them so that you can select, modify, or remove them. The Dynamic Simulation browser has the following parts:

Element names

Assembly

Name of the mechanism.

Parts

Part name (assigned during part creation), a colon (:), and the occurrence number.

Joints

The type of joint, a colon (:), joint number, and in parentheses, the names and numbers of the two joint components. For example: Revolution:1 (part1:1, part2:1)

Gravity

Gravity.

Forces

Force number (assigned according to the order of external force creation), and, in parentheses, the name of the part receiving the force.

Torques

Torque number (assigned according to the order of external torque creation), and, in parentheses, the name of the part receiving the torque.

Special conditions

Identifies a joint with an internal force or torque applied, an imposed motion, or any other user inputs in the joint property box (for example, bounds).

Identifies a joint that makes the kinematic chain over constrained.

Any unavailable item is disabled or suppressed. This issue may be because the item is either suppressed by the software for various reasons or intentionally suppressed by the user.

This condition occurs when the assembly constraints of a standard joint are suppressed

Revolution:1 (door:1, pillar:1)

Bold letters identify parts linked to selected objects.

Context menu commands

The following are the options that may appear on a context menu.

Adaptivity

Sets the component’s adaptivity state. Adaptive components may change during component editing. Before setting this state, you should familiarize yourself with adaptivity concepts.

Add Force

Opens the Force dialog box. Add an external force except gravity.

Available when you right-click External Loads.

Add a joint

Opens the Insert Joint dialog box. Add a joint manually.

Available when you right-click Rolling Joints, Sliding Joints, Contact Joints, or Force Joints.

Add Torque

Opens the Torque dialog box. Add an external torque.

Available when you right-click External Loads.

Body Properties

Opens the Body Properties dialog box for the selected item. Edit properties for the item.

Available when you right-click the grounded group, a grounded part or subassembly, or a joint.

Burst weldment

Undoes a weld. Right click a welded group.

Only available if Automatically Convert Constraints to Standard Joints is off.

Color Mobile groups

Assigns predefined colors to the various mobile groups. The Grounded group uses the color “glass”. If the Glass color is not present in the Styles Library, the assigned assembly color of the component is used. This option aids in analyzing component relationships. To return the components to their normally assigned colors, uncheck the checkbox in the settings dialog box or right click the Mobile Groups node and select Color Mobile Groups

Constraint

Displays the constraint creation dialog box. Add constraints to the assembly. Added constraints display in the browser relative to the components they are used applied to.

Contact Set

Adds the selected component to a contact set.

Create Component

Opens the Create Component dialog box. Create a component in the context of the assembly. Available when right-clicking in browser blank space and when clicking the display background with nothing selected.

Define gravity

Opens a dialog box. Unsuppress gravity and define the gravity vector. Available when you right-click gravity.

Delete

Deletes the selected item from the mechanism.

Available when you right-click a constraint, a trace, a force, a torque, or a part selected for export to FEA.

Delete all joints

Deletes all joints in the selected category.

Available when you right-click Standard Joints (except when Automatically Convert Constraints to Standard Joints is selected), Rolling Joints, Sliding Joints, Contact Joints, or Force Joints.

Delete joint (actuator for a spring/damper/jack joint)

Deletes the selected joint.

Available when you right-click any joint except a standard joint when Automatically Convert Constraints to Standard Joints is selected.

Dimension Display

Expands to display a list of dimension display options. The command is associated with the assembly modeling environment.

Edit

Component

Available with components, this command edits the model in place within the assembly context, Assembly components that are not being edited are shown in a faded condition.

Constraint

Opens the Constraint dialog box. Edit the constraint.

Changing the constraint will affect the joint type.

Force

Opens the Force dialog box. Modify the definition of the selected external force.

Available when you right-click any external force except gravity.

Joint

Opens the Insert Joint dialog box. Edit the definition of the selected joint.

Available when you right-click a standard joint, a 2D contact joint, or a force joint.

Torque

Opens the Torque dialog box. Modify the definition of the selected external torque.

Available when you right-click any external torque.

Enabled

Right click a component in the model browser or graphics area. Defines component selectability. When enabled a component can be selected. When not enabled, a component cannot be selected.

Find

Opens the Find dialog box. Locate a particular element quickly.

Available when you right-click the assembly.

Flexible

Right click a component in the model browser or graphics area. Defines a subassembly state. When flexible, joints can be added to the subassembly. When not flexible the subassembly is rigid.

Grounded

Sets the grounded condition for a part in an assembly. Grounding removes all degrees of freedom from a component. Changing a component’s grounded state in the simulation context causes the joints to update and deactivates joints where necessary.

Help topics

Opens the Help home page.

Available when you right-click anything in the Dynamic Simulation browser.

Ignore DOF

Right click a component in the model browser or graphics area. Some actions cause a change to the degrees of freedom (DOF). If it is not what you want, you can set Ignore DOF and override the change. Enabled when Automatically Convert Constraints to Standard Joints is active.

iMate Glyph Visibility

Toggles iMate glyph visibility.

Isolate Components

Hides components that are not involved in resolving the select constraint. Accessed from the constraint context menu.

Lock DOFs

Locks all of the degrees of freedom for the selected joint.

Available when you right-click a standard joint.

Measure

Displays a list of available measure commands from which you can choose. These are commands related to the assembly environment.

Open

Opens the selected model in a separate window. If a subassembly, you see only those parts participating in that assembly. If a single part, you see no other components.

Place Component

Opens the Place Component dialog box. Place a component in the assembly. Available when right-clicking in browser blank space and when clicking the display background with nothing selected.

Rebuild weldment

Updates the weldment to include latest modifications.

Available when you right-click the grounded group or a grounded part or subassembly. Only available if Automatically Convert Constraints to Standard Joints is off.

Retain DOF

Right click a component in the model browser or graphics area. Some actions cause a change to the degrees of freedom (DOF). If this behavior is not what you want, you are able to set Retain DOF and override the change. Enabled when Automatically Convert Constraints to Standard Joints is active and specific constraint conditions were met, such as gear sets, pins, and so on. It allows the dynamic simulation environment to remove DOF for things like bolts, screws, cotter pins, and so on, thereby simplifying the kinematic chain.

Suppress

Constraint

Removes the constraint from contributing to the definition of the joint. This results in joint type changes or joint deactivation.

Force

Removes the selected force from all subsequent calculations without removing it from the mechanism.

Joint

Removes the selected joint from all subsequent calculations without removing it from the mechanism.

Torque

Removes the selected torque from all subsequent calculations without removing it from the mechanism.

Weld parts

Welds one grounded component to one mobile component.

Available when you select both a component in the grounded group and a component in the mobile group and then right-click the component in the mobile group. Automatically Convert Constraints to Standard Joints must be set to Off.

Note: Both components must be selected for Weld parts to be available.

Visibility

Makes this component visible in the graphics window.

A check mark to the left of the command shows that it is enabled.

Available when you right-click a part or a subassembly.
