Which Inventor command creates a surface that fills a closed loop of edges or sketch curves?
Answer: Boundary Patch
Boundary Patch generates a planar or 3D surface bounded by a closed loop of edges or curves.
When Stitch joins surfaces that fully enclose a volume, what does Inventor create by default?
Answer: A solid body
Stitch converts a watertight set of surfaces into a solid unless the Maintain as Surface option is selected.
Which option in the Stitch dialog keeps a fully closed result as a surface instead of a solid?
Answer: Maintain as surface
The Maintain as surface checkbox stops Stitch from automatically turning a closed quilt into a solid.
What does the Stitch tolerance value control?
Answer: The largest gap between edges that can still be joined
Edges whose gaps fall within the tolerance are treated as coincident and stitched together.
In a Boundary Patch, which edge condition gives curvature-continuous (G2) blending with an adjacent face?
Answer: Smooth (G2)
The Smooth (G2) condition matches both tangency and curvature at the selected edge.
Where does Inventor list surface bodies created in a part file?
Answer: Under the Surface Bodies folder in the browser
Surface bodies are grouped in their own Surface Bodies folder in the model browser.
How do you make an Extrude produce a surface instead of a solid?
Answer: Set the output to Surface in the Extrude properties
Extrude, Revolve, Sweep, and Loft all have a Surface output option that produces a surface body.
