An electronic device includes a plug-in module including a printed substrate on which an electronic circuit is mounted, and a baseplate to which the plug-in module is detachably connected, wherein a system side and a field side are connected with each other, and a predetermined option function is included in the plug-in module. The novel system and method allows for quick and efficient modification of all or a portion of a plurality of data fields, while preserving the ability to modify individual areas. The present invention allows a user to use a region directly as an input argument for a part body modeling operation as long as a sheet body is applicable as a modeling input argument.
