I have been asked to provide a cross section / cutt-out of a .brd to send to Reliability Engineering for import into Ansys for Thermal Analysis. Is there a way to cutt away unwanted sections of the design quickly? The area of interest is under the package of a large BGA.
I am also interested in percentage of copper on each layer under this package. I have ran a film area report, however the reported numbers are not in allignment with my manual calculations used for verifying the reports accuracy. Any ideas? Any and all help would be greatly appreciated.
