The drafting of polygons is done in the same way as for polylines, except that you have to indicate a minimum of 3 vertices at this point. Each side can be assigned a specific length or angle.
Regular polygons, on the other hand, are drafted by indicating the centre and radius of the circumcircle and the number of sides (from 3 to 99) as well as the angle of rotation.
All polygons can have the double line attribute enabled, so that a parallel-sided polygon can be added at a given distance. It is also possible to hatch the polygon.
