Multi-angle keel automatic typesetting method

The invention discloses a multi-angle keel automatic typesetting method. The method comprises the following steps: S1, compiling a function module; s2, loading a spread function library; s3, setting a width value of the polyline; s4, reading the name of the current layer and assigning a value; s5, inputting a keel number, and assigning txt; s6, inputting layers and keel colors, assigning the colors to color, and distinguishing different keel typesets by using specified colors; s7, calling a layserch module, and establishing a layer by taking the keel number and the specified color as parameters; s8, selecting a size mark for expressing the drawing keel size and the arrangement diagram, and assigning a value to the selection set ss for expressing the relative spatial arrangement of the keel; s9, keel arrangement base points are selected, pt is assigned, pt is used as reference coordinates, and all keel arrangements are expressed through the angle and distance relation between the end points and the relative ba
