Boardview in CAD format, 2.61 MB, which by its name corresponds to the MSI-style board code V317, apparently revision 1.1 judging by the 11 suffix. The name gives no card model, so identify the board by the MS-V317 marking on the PCB before using it. CAD boardview files open in tools such as OpenBoardView, FlexBV or Boardviewer and show part placement, pins and net connections. They help locate components, follow power rails, find test points and trace shorts, ideally alongside the matching MS-V317 rev 1.1 schematic.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @laptexdna. Enginerys does not host this file.
