Sheet Metal Design Flashcards

Which Flange width extents option makes a flange of a set length centered on the selected edge?

Answer: Width (with Centered)

The Width extent with the Centered option makes a flange of a fixed width centered on the edge.

When you use the Fold command, what must the sketch line do?

Answer: Lie on the sheet metal face and reach its edges

Fold bends the face along a sketch line that lies on the face and ends on its edges.

A shelled box was converted to sheet metal but cannot be flattened because it is fully closed. Which command adds the needed gap?

Answer: Rip

Rip makes a gap (single point, point to point, or face extents) so a closed shape can be unfolded.

A common reason a flat pattern fails to generate in a sheet metal part is:

Answer: The part does not have a uniform thickness

Unfolding needs a uniform thickness, so features that change the thickness make the flat pattern fail.

Which command adds manufacturing mark lines that are not bends and that carry into the flat pattern and DXF export?

Answer: Cosmetic Centerline

Cosmetic centerlines add reference marks, such as scribe lines, that appear in the flat pattern and in exports.

In an Inventor drawing, which annotation lists each bend's ID, direction, angle, and radius in a table?

Answer: Bend Table

The Bend Table shows bend data, such as direction, angle, and radius, for flat pattern views.

In the Inventor Default sheet metal rule, what is the default bend radius set to?

Answer: Thickness

The Default rule sets the bend radius equal to the Thickness parameter.
