Properties specific to sheet metal parts are calculated and displayed in the Cut-List Properties dialog box.
Some of the properties that are calculated are based on the bounding box, the smallest rectangle in which the flat pattern can fit. You can set a grain direction to determine the smallest rectangle that aligns with the grain direction to fit the flat pattern. The bounding box is represented by a sketch when you flatten the sheet metal part and is located in the FeatureManager design tree under Flat-Pattern 
.
Example of bounding box sketch in a flat pattern:
The following properties are calculated in sheet metal parts:
- Bounding Box Length
- Longest side of the bounding box
- Bounding Box Width
- Shortest side of the bounding box
- Sheet Metal Thickness
- Bounding Box Area
- Bounding box length x Bounding box width
- Bounding Box Area-Blank
- Area of the flat pattern excluding the through cut-outs
- Cutting Length-Outer
- Outer perimeter of the flat pattern (blank), which is used for calculating the machine’s cutting time
- Cutting Length-Inner
- Sum of the perimeters of internal loops or cut-outs
- Cut Outs
- Closed cut outs (through holes) on the flat pattern, which are used for calculating the machine’s idle time
- Bends
- Number of bends in the part
- Bend Allowance
- Basis of the flat pattern calculation
- Material
- Mass
- Description
- Bend Radius
- Surface Treatment
