A geological section map elevation calculation method based on a CATIA engineering drawing

The invention discloses a CATIA engineering drawing-based geological profile elevation calculation method. The method comprises the following steps of: specifying a profile line in a three-dimensionalgeological model; determining geographic coordinates of two end points of the profile line; calculating relevant parameters of the profile line; obtaining parameters related to an XY plane front viewof the three-dimensional geological model; defining section view parameters; drawing a geological profile map according to the defined profile parameters to obtain a profile view; Acquiring relevantparameters of the profile view; solving coordinates of the two end points of the line segments A and B in a profile view coordinate system; solving the distance h from the central point of the profileview to the bottom edge of the profile view; solving the maximum height of the section; obtaining view related parameters after the view is rotated; and elevation calculation: calculating a profile view bottom elevation Zy.
