File Size Use it when
tms320f28035pntr.step 1051 KB You want the bare part, or you mark your own boards.
tms320f28035pntr-etched.step 7.2 MB You want the part with TMS320F28035PNTR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 1771 faces against 1235 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
