As of now, we do not support Cadstar yet but we are going to add this on our feature board of new EDA tools to support it in the future.
I tried searching for the file formats it supports but i haven't had any luck. What i found out is that it can only import schematic and pcb designs from PADS, OrCAD and Altium but not libraries.
