title: MODELING OF THE 2ND ORDER CURVES AND SURFACES OF ENGINEERING STRUCTURES SHELLS BASED ON THEIR BASIS
abstract: The paper describes an example of modeling an arc of a 2nd order curve using an engineering discriminant and its analytical description based on a graphical algorithm for constructing a curve in point calculus. Examples of modeling the surfaces of engineering structures shells on an elliptical and rectangular plan are given. Research methods include geometric algorithms: modeling of 2nd order curves passing through 3 predetermined points in advance and having tangents at the start and end points
