Schematics don’t do you much good on today’s high-tech electronics. Most high-tech electronics nowadays use custom chips or FPGAs so a schematic that shows all the signals going in and out of a magic proprietary chip won’t do you any good.
A lot of lower-tech components that perhaps use discrete parts, przekaźniki, discrete resistors, itp. do have schematics on the inside of the case or available online.

I need to add a resistor into a data line on my project. The data line is a trace and carries low speed data. A through-hole resistor will be fine. The pins for both ends of the trace are exposed, but how do I add the resistor and remove the trace?
My EDA software (PCAD, but I guess others do this too) adds thermal reliefs on vias in a copper pour. What’s the use? Vias aren’t soldered.
I am designing a 2 layer PCB with components on both side of it. SMT components are one one side of PCB, but TH (through hole) components are on both sides. I need to understanding something mentioned by the supplier called primary and secondary sides.
