Fusion 360 Sheet Metal Design 3

Question 1

What is a 'lofted flange' in Fusion 360 sheet metal design?

Accepted Answer

A flange that connects two non-parallel edges or profiles, forming a transition shape

Answer

A lofted flange creates a transitional sheet metal wall between two open-profile sketches, allowing tapered or warped sheet metal geometry.

Question 2

Which Fusion 360 sheet metal rule parameter ensures consistent bend properties across an entire part?

Accepted Answer

Sheet Metal Rule

Answer

Sheet Metal Rules store the default thickness, bend radius, K-factor, and relief type, applying them uniformly to all features unless overridden.

Question 3

What does the 'Rip' command do in the Fusion 360 Sheet Metal workspace?

Accepted Answer

Creates a gap along a model edge or corner to allow unfolding of closed shapes

Answer

The Rip command separates material at a corner or edge so that a closed solid or folded shape can be unfolded into a proper flat pattern.

Question 4

How is 'bend allowance' different from 'bend deduction' when calculating flat patterns?

Accepted Answer

Bend allowance is added to leg lengths to get flat length; bend deduction is subtracted from the sum of leg lengths

Answer

Bend allowance is the arc length of the neutral axis through the bend zone; bend deduction is the amount subtracted from the total of both flange lengths to get the flat length.

Question 5

Which file format is most commonly used to export a flat pattern from Fusion 360 for laser cutting?

Accepted Answer

DXF

Answer

DXF (Drawing Exchange Format) is the standard output for flat patterns because laser cutters and punch presses commonly accept 2D DXF geometry.
