GMetrix Exam GMetrix Inventor: 3D Part Creation 4 — Questions and Answers
Question 1: In Inventor, which sketch tool draws a straight line segment that automatically becomes construction geometry?
- Construction Line (toggled via the Construction button) (Correct answer)
- Center Line
- Project Geometry
- Reference Line
Correct answer: Construction Line (toggled via the Construction button)
Enabling the Construction toggle before or after drawing a line marks it as construction geometry, which guides but does not define the profile boundary.
Question 2: Which Inventor termination type extrudes a feature exactly to the surface of an existing face, even if that face is curved?
- To Surface (Correct answer)
- To Next
- Through All
- Distance
Correct answer: To Surface
The 'To Surface' termination ends the extrusion precisely at a selected face, conforming to any contour that face has.
Question 3: What is the primary difference between a 'Fillet' and a 'Chamfer' edge treatment in Inventor?
- Fillet creates a rounded edge; Chamfer creates an angled flat edge (Correct answer)
- Fillet removes more material than Chamfer
- Chamfer is only for interior edges; Fillet is for exterior edges
- They are identical but applied to different feature types
Correct answer: Fillet creates a rounded edge; Chamfer creates an angled flat edge
A Fillet blends two faces with a curved radius, while a Chamfer cuts a straight angled surface between them.
Question 4: In Inventor, the 'Project Geometry' tool in a sketch is used to:
- Copy edges or points from existing 3D geometry onto the active sketch plane (Correct answer)
- Align the sketch plane to a selected face
- Move the part to a new position in the assembly
- Display the part in an orthographic projection
Correct answer: Copy edges or points from existing 3D geometry onto the active sketch plane
Project Geometry traces selected edges, vertices, or curves from 3D model faces onto the current sketch, creating reference lines for new sketch geometry.
Question 5: Which Inventor browser environment contains parameters that control overall part dimensions and can be referenced by multiple features?
- Parameters (fx: Parameters dialog) (Correct answer)
- Properties
- iProperties
- Feature Manager
Correct answer: Parameters (fx: Parameters dialog)
The Parameters dialog (opened via Manage > Parameters) stores named dimensional values that features and sketches can reference, enabling parametric design.
Question 6: What does the 'Rib' feature in Inventor create?
- A thin structural support wall added between two faces (Correct answer)
- A series of parallel grooves cut into a surface
- A raised text embossment
- A hollow tube connecting two solid regions
Correct answer: A thin structural support wall added between two faces
The Rib feature builds a thin web or gusset from an open sketch profile between existing solid faces, used to add structural strength.
Question 7: In Inventor's Hole feature dialog, which hole type produces a conical countersink angle for a flat-head screw?
- Countersink (Correct answer)
- Counterbore
- Drilled
- Tapped
Correct answer: Countersink
A Countersink hole has a conical angled entrance that allows flat-head screws to sit flush with or below the surface.
