GMetrix Exam GMetrix Inventor: 3D Part Creation 3 — Questions and Answers
Question 1: In Autodesk Inventor, which panel or browser entry lets you edit the dimensions and constraints of a previously created feature?
- Model Browser (right-click > Edit Feature) (Correct answer)
- Quick Access Toolbar
- Status Bar
- View Cube
Correct answer: Model Browser (right-click > Edit Feature)
Right-clicking a feature in the Model Browser and choosing Edit Feature reopens its dialog so you can modify parameters.
Question 2: What does the 'Symmetric' termination option do when extruding a feature in Inventor?
- Extends the feature equally in both directions from the sketch plane (Correct answer)
- Mirrors the extrusion to another part
- Applies a taper on both sides
- Creates a second body on the opposite side
Correct answer: Extends the feature equally in both directions from the sketch plane
The Symmetric termination extrudes the profile an equal distance on both sides of the sketch plane simultaneously.
Question 3: Which Inventor command creates circular copies of features or geometry arranged around an axis?
- Circular Pattern (Correct answer)
- Mirror
- Rectangular Pattern
- Array
Correct answer: Circular Pattern
Circular Pattern duplicates selected features or bodies around a rotation axis at equal or specified angular intervals.
Question 4: When you apply a 'Tangent' constraint between a line and an arc in Inventor, what does it ensure?
- The line meets the arc without a sharp corner at the contact point (Correct answer)
- The line is parallel to the arc's chord
- The line bisects the arc
- The arc's radius matches the line's length
Correct answer: The line meets the arc without a sharp corner at the contact point
A Tangent constraint ensures the line and arc share a smooth, corner-free transition at their point of contact.
Question 5: In Inventor, what is a 'Work Axis' primarily used for?
- As a reference axis for features like Revolve, Circular Pattern, or Holes (Correct answer)
- To display the X, Y, Z coordinate system
- To anchor the part to an assembly
- To define a cutting plane
Correct answer: As a reference axis for features like Revolve, Circular Pattern, or Holes
Work Axes are construction geometry that provide a reusable reference axis for revolves, patterns, and other axis-dependent features.
Question 6: Which Inventor feature is specifically designed to create a helical or spiral form, such as a spring or thread profile?
- Coil (Correct answer)
- Sweep
- Loft
- Emboss
Correct answer: Coil
The Coil feature generates helical geometry by winding a profile around an axis, making it ideal for springs and thread representations.
Question 7: What does the 'Shell' command do to an existing solid in Inventor?
- Hollows out the solid, leaving walls of a specified thickness (Correct answer)
- Splits the solid into separate bodies
- Wraps a surface around the solid
- Adds a thin rib to the outside
Correct answer: Hollows out the solid, leaving walls of a specified thickness
Shell removes the interior of a solid and keeps a uniform wall thickness, commonly used for plastic enclosures and containers.
