Sometimes during the nesting through the ATP if Shapes have Open Contours involved, the nesting will make a terrible yield of the material because the Shapes will behave like they are rectangles.

Example: ShapeMaster creating a Two Triangular shapes, with Flaps around the outside, the Two Shapes will nest like Rectangles in EzyNest, instead of Shapes.

Firstly Nesting in EzyNest with the <NestOpenContour> set to "2" using a 5Deg Rotation.

Secondly Nesting in EzyNest with the <NestOpenContour> set to "0" using a 5Deg Rotation.

In the EnRoutePreferences.xml file there is a choice called <NestOpenContour>
