Method for automatically counting engineering quantity of hydraulic metal structural plate components

The invention discloses a method for automatically counting the engineering quantity of hydraulic metal structural plate components, and relates to the field of hydraulic metal structural design. A three-dimensional model of a product is designed by utilizing a 3DE platform, a structural tree of the three-dimensional model is retrieved, and all plate component geometries of the product are obtained; the geometry of the plate component comprises a primary forming feature, a sketch contour, a secondary forming feature and a material list parameter set. And identifying and calculating the overall dimension of the geometric body of the plate component, and representing the specification and dimension of the geometric body of the plate component and the material and density of the geometric body of the plate component by using the product of the characteristic value and the overall dimension. The unit weight of the plate component required by the plate component geometry is obtained by using the product of the spe
