Inverting normals of surfaces can be executed by selecting <Inverse> from popup menu on selected objects in geometrical structure window.

For non "double sided" surfaces (the <Machining> page of the <Object properties> window), the side of the surface to be machined can be defined by this function. The surface will be machined from that side only, where the normal vector is pointing. To create the correct NC program it is necessary that normal vectors of all its elements have the direction from the detail.

For "double sided" faces (all faces are "double sided" after the import process as default), the direction of the normal is unimportant. Use of the inversion function does not affect the tool movement toolpath.


Attention:        Incorrect direction of the normal vectors for non "double-sided" surfaces may cause faulty results during execution of machining operations.
