and a communication interface; wherein the processor is configured to: generate a virtual plant based on various types of drawings of a plant; update the virtual plant, when a change is made to a drawing among the various types of drawings, based on the change; and notify a predetermined recipient, via the communication interface, of information related to a change made to the virtual plant by updating. ### Claim 2 (depends on 1) The drawing management apparatus of claim 1, wherein the processor is configured to perform verification of whether an element changed at a time of updating of the virtual plant is an element needing to be listed in the various types of drawings at the time of updating and include a result of the verification in the information related to the change made to the virtual plant by updating. ### Claim 3 (depends on 1) The drawing management apparatus of claim 1, wherein the processor is configured to perform verification of whether an element changed at a time of updating of the virtual plant is reflected in the various types of drawings at the time of updating and include a result of the verification in the information related to the change made to the virtual plant by updating. ### Claim 4 (depends on 2) The drawing management apparatus of claim 2, wherein the processor is configured to perform verification of whether an element changed at a time of updating of the virtual plant is reflected in the various types of drawings at the time of updating and include a result of the verification in the information related to the change made to the virtual plant by updating. ### Claim 5 (depends on 2) The drawing management apparatus of claim 2, wherein the processor is configured to perform the verification on various types of drawings other than the drawing changed at the time of updating. ### Claim 6 (depends on 3) The drawing management apparatus of claim 3, wherein the processor is configured to perform the verification on various types of drawings other than the drawing changed at the time of updating. ### Claim 7 (depends on 4) The drawing management apparatus of claim 4, wherein the processor is configured to perform the verification on various types of drawings other than the drawing changed at the time of updating. ### Claim 8 (depends on 1) A drawing management system comprising: the drawing management apparatus of claim 1; and at least one terminal apparatus capable of communicating with the drawing management apparatus. ### Claim 9 (depends on 2) A drawing management system comprising: the drawing management apparatus of claim 2; and at least one terminal apparatus capable of communicating with the drawing management apparatus. ### Claim 10 (depends on 3) A drawing management system comprising: the drawing management apparatus of claim 3; and at least one terminal apparatus capable of communicating with the drawing management apparatus. ### Claim 11 (depends on 4) A drawing management system comprising: the drawing management apparatus of claim 4; and at least one terminal apparatus capable of communicating with the drawing management apparatus. ### Claim 12 (depends on 5) A drawing management system comprising: the drawing management apparatus of claim 5; and at least one terminal apparatus capable of communicating with the drawing management apparatus. ### Claim 13 (depends on 6) A drawing management system comprising: the drawing management apparatus of claims 6; and at least one terminal apparatus capable of communicating with the drawing management apparatus. ### Claim 14 (depends on 7) A drawing management system comprising: the drawing management apparatus of claim 7; and at least one terminal apparatus capable of communicating with the drawing management apparatus. ### Claim 15 A drawing management method using a computer, the drawing management method comprising: generating a virtual plant based on various types of drawings of a plant; updating the virtual plant, when a change is made to a drawing among the various types of drawings, based on the change; and notifying a predetermined recipient of information related to a change made to the virtual plant by updating.
