## What is self intersecting?

Self-intersecting polygons, crossed polygons, or self-crossing polygons are **polygons some of whose edges cross each other**. They contrast with simple polygons, whose edges never cross. Some types of self-intersecting polygons are: the crossed quadrilateral, with four edges.

## How do I repair a sketch in Solidworks?

## How do you determine if an intersecting polygon is self?

To determine if a polygon is self-intersecting using MapObjects, **simply intersect the polygon with its own Extent**. If the result is Nothing (nil), then the polygon is self-intersecting.

## How do you find self-intersection?

A self-intersection will be a singular point of the curve, and the singular points can be found by **solving the system of equations [; f(x,y) = f_x(x,y) = f_y(x,y) = 0 ;]** , which can again be done with Gröbner bases.
