CSWP Motion Studies 4 — Questions and Answers
Question 1: Which SOLIDWORKS tool allows you to export a completed motion animation as an AVI or MP4 video file?
- Save As → Part Template
- Save Animation button in the Motion Study toolbar (Correct answer)
- PhotoView 360 → Final Render
- File → Pack and Go
Correct answer: Save Animation button in the Motion Study toolbar
The Save Animation button renders the motion study timeline to a video file in a format and resolution you specify.
Question 2: In Motion Analysis, what is the role of 'material' properties (density) assigned to components?
- They affect only rendered appearance, not simulation
- They are used to calculate component mass, which affects inertia and dynamics (Correct answer)
- They define friction coefficients for contact
- They set the spring constant automatically
Correct answer: They are used to calculate component mass, which affects inertia and dynamics
Mass (derived from density × volume) determines inertial resistance to acceleration, which is fundamental to accurate dynamic simulation.
Question 3: When you right-click a result plot in the Motion Analysis Results panel, which option lets you export the plotted data as a CSV file?
- Export CSV
- Save Plot Data
- Export to Excel / Save Plot Data (varies by version) (Correct answer)
- Copy to Clipboard Only
Correct answer: Export to Excel / Save Plot Data (varies by version)
Right-clicking a Motion Analysis result plot offers an option to export or save the tabular data (the exact label may vary by SOLIDWORKS version).
Question 4: What happens to mates that are 'Suppressed' during a Motion Analysis study?
- They are treated as rigid locks
- They are ignored by the solver, removing those kinematic constraints (Correct answer)
- They cause an error and must be deleted
- They are automatically converted to spring elements
Correct answer: They are ignored by the solver, removing those kinematic constraints
Suppressed mates are excluded from the solver's constraint set, effectively allowing those degrees of freedom to be free.
Question 5: In a Basic Motion study, which physical effect is approximated but NOT as rigorously as in Motion Analysis?
- Gravity direction
- Motor velocity
- Contact and collision dynamics (Correct answer)
- Camera path
Correct answer: Contact and collision dynamics
Basic Motion includes simplified collision and spring behavior, but lacks the full rigid-body dynamics accuracy of Motion Analysis.
Question 6: A key point diamond icon appears GRAY (faded) on the Motion Study timeline. What does this typically indicate?
- The key is locked and cannot be moved
- The key is on a suppressed mate or feature and is inactive (Correct answer)
- The key represents a camera position
- The key stores a photorealistic render setting
Correct answer: The key is on a suppressed mate or feature and is inactive
Faded/gray key diamonds usually indicate the associated feature or mate is suppressed, so the key has no active effect.
Question 7: Which Motion Analysis solver setting controls how accurately and finely the solver integrates equations of motion over time?
- Frames per second
- Integrator Type and Accuracy (solver tolerance) (Correct answer)
- Number of key points
- Mass scaling factor
Correct answer: Integrator Type and Accuracy (solver tolerance)
The integrator type (e.g., GSTIFF, WSTIFF) and its accuracy/tolerance setting determine the step-size control and numerical precision of the dynamic solver.
