摘要 |
A drawing management device for managing the drawing of an entire facility, such as a water supply facility, as digital information. This device includes a unit for storing drawings with priorities obtained by separating the entire facility drawing into sub-facility drawings located at plural levels, a selective display designating unit for displaying a desired sub-facility drawing obtained by selecting the number of levels considering the priority from the storing unit, and a display unit for displaying the desired sub-facility drawing in response to the signal from the selective display designating unit. By suitably selecting a desired level considering the priority, only a necessary and sufficient facility drawing can be displayed swiftly.
