I want to use the system CN0185 specifically the filter at the end for a school project but i cant seem to open it and it only shows me this error message:
What can i do in this situation?
AndrewDide Unfortunately, that .asc file in the CN0185 file package is a PADs file: https://help.solidworks.com/2022/English/SolidWorks/circuitworks/c_pads_ascii_format.htm
That said, we have a fiew tools that might help you create a schematic that can be exported to LTspice.

If you want to try to build this circuit using Filter Wizard, the circuit note gives some clues about what the parameters to give Filter Wizard:
Then - in the components selection view, change the supplies to a single 5V supply, and change out the automatically chosen op amps with the AD8646:
Keep working on your design, until you are ready to generate LTspice files at the last tab view:
Hopefully this helps you make some progress.
