Dredging work amount automatic generation method based on Civil 3D

The invention discloses a Civil 3D-based dredging engineering quantity automatic generation method, which comprises the following steps of: A1, sending a prompt message to a user to prompt the user to select a created dredging road; a2, creating a two-dimensional auxiliary curved surface according to a dredging road fed back by a user; a3, a prompt message is sent to the user, and the user is prompted to select the current terrain curved surface; a4, a three-dimensional volume curved surface is created, the address of the current terrain curved surface and the two-dimensional auxiliary curved surface are transmitted to the three-dimensional volume curved surface, and a dredging engineering quantity volume curved surface is obtained; and A5, according to the dredging engineering quantity volume curved surface, the dredging engineering quantity of each part is obtained by using the viewing attribute of Civil 3D. Through the steps of the method, the total dredging engineering quantity can be quickly and automati
