The processor is configured to notify, via the communication interface, a user or terminal apparatus handling a second type of drawing different from a first type of drawing of information related to a difference in the first type of drawing acquired based on a comparison between a new version and an old version of the first type of drawing. ## Claims ### Claim 1 A drawing management apparatus for managing various types of drawings of a plant, the drawing management apparatus comprising a processor and a communication interface; wherein the processor is configured to notify, via the communication interface, a user or terminal apparatus handling a second type of drawing different from a first type of drawing of information related to a difference in the first type of drawing acquired based on a comparison between a new version and an old version of the first type of drawing. ### Claim 2 (depends on 1) The drawing management apparatus of claim 1, wherein the processor is configured to notify, via the communication interface, the user or the terminal apparatus handling the second type of drawing of information related to an element necessary in the second type of drawing among elements included in the difference in the first type of drawing. ### Claim 3 (depends on 2) The drawing management apparatus of claim 2, wherein the processor is configured to refer to a data table including information related to necessity of elements in the various types of drawing of the plant and to judge whether any of the elements included in the difference in the first type of drawing is necessary in the second type of drawing. ### Claim 4 (depends on 1) The drawing management apparatus of claim 1, wherein the processor is configured to notify, via the communication interface, the user or the terminal apparatus handling the second type of drawing of information related to an element not reflected in the second type of drawing among elements included in the difference in the first type of drawing. ### Claim 5 (depends on 2) The drawing management apparatus of claim 2, wherein the processor is configured to notify, via the communication interface, the user or the terminal apparatus handling the second type of drawing of information related to an element not reflected in the second type of drawing among elements included in the difference in the first type of drawing. ### Claim 6 (depends on 3) The drawing management apparatus of claim 3, wherein the processor is configured to notify, via the communication interface, the user or the terminal apparatus handling the second type of drawing of information related to an element not reflected in the second type of drawing among elements included in the difference in the first type of drawing. ### Claim 7 (depends on 1) The drawing management apparatus of claim 1, wherein the processor is configured to perform the comparison when acquiring the new version of the first type of drawing. ### Claim 8 (depends on 2) The drawing management apparatus of claim 2, wherein the processor is configured to perform the comparison when acquiring the new version of the first type of drawing. ### Claim 9 (depends on 3) The drawing management apparatus of claim 3, wherein the processor is configured to perform the comparison when acquiring the new version of the first type of drawing. ### Claim 10 (depends on 4) The drawing management apparatus of claim 4, wherein the processor is configured to perform the comparison when acquiring the new version of the first type of drawing. ### Claim 11 (depends on 5) The drawing management apparatus of claim 5, wherein the processor is configured to perform the comparison when acquiring the new version of the first type of drawing. ### Claim 12 (depends on 6) The drawing management apparatus of claim 6, wherein the processor is configured to perform the comparison when acquiring the new version of the first type of drawing. ### Claim 13 (depends on 1) The drawing management apparatus of claim 1, wherein the processor is configured to perform the comparison when a predetermined period is reached. ### Claim 14 (depends on 1) The drawing management apparatus of claim 1, wherein the processor is configured to notify, via the communication interface, the user or the terminal apparatus handling the second type of drawing of information related to the difference in the first type of drawing when the difference in the first type of drawing exceeds a predetermined threshold. ### Claim 15 (depends on 1) The drawing management apparatus of claim 1, wherein the processor is configured to notify, via the communication interface, a user or terminal apparatus handling the first type of drawing of information related to a difference acquired by excluding the difference in the first type of drawing from a difference in the second type of drawing acquired based on a comparison between a new version and an old version of the second type of drawing. ### Claim 16 (depends on 1) A drawing management system comprising the drawing management apparatus of claim 1 and the terminal apparatus. ### Claim 17 A drawing management method for managing various types of drawings of a plant using a computer, the drawing management method comprising: notifying a user or terminal apparatus handling a second type of drawing different from a first type of drawing of information related to a difference in the first type of drawing acquired based on a comparison between a new version and an old version of the first type of drawing.
