3D CAD Envelope discrepency between Thermal Design Guide & Downloadable File


There’s a discrepancy between the 3D model shown in Figure 4-1 in the thermal design guide (TDG) , and the downloadable .step file (version 20230320). Please see below images for discrepancies:

Specifically, the TDG shows a space envelope occupying the area shown as yellow in the .step file. It also shows a square space envelope in the centre (presumably where the die is), but this is not present in the .step file.

Which model is correct?

Thank you!
