Advanced Sheet Metal Design Using NX Cad Challenge_2_Box Assembly
Sheetmetal Box Assembly Design
Objective
To design the Sheetmetal Box assembly using the CAD software (Siemens NX - Sheetmetal Application)
Introduction
Sheetmetal application provides an environment for the design of sheetmetal parts used in machinery, automotive, and various industries
Design Approach
The design workflow of the Sheetmetal Box assembly is given below

Description
The following features were used in the Sheetmetal Box assembly design
- Sketch
2D sketch of the part is created in the sheetmetal application
- Tab
It is the base feature created by extruding the sketch along a vector by a thickness value
- Flange
This command is used for adding a flat flange at an angle to a planar face and adding a bend between the two sides
- Closed corner
This command is used for closing a corner where two adjacent flanges meet by extending the bends and flanges
- Hem flange
This command is used for modifying the model by folding the edge of a sheet metal flange over onto itself for the purpose of safe handling or to increase edge stiffness
- Mirror body
This feature used for creating associative copies of bodies with the part
- Unite
This feature used for combining the volume of two or more bodies into single body
- Dimple
The spine area of the part is lifted using this command
- Mirror feature
This command is used to copy a feature and mirror it across a plane
- Bead
This command is used for lifting material along the contour of a sketch that simulates a stamping tool
- Break corner
The sharp corners are made round or chamfer with this command
- Unbend
This command is used for flattening a bend and the material adjacent to the bend
- Normal cut-out
Cut-outs in sheetmetal is made with this command which cuts material by projecting a sketch onto the model and then cutting perpendicular to the faces intersected by the projection
- Re-bend
This command is used for restoring an unbend feature to its previous bend state, along with any features added after the unbend feature
