Feature Log: External References

External references are specifically marked in the feature log. The type of the external reference will be distinguished, in particular with regard to whether it is actually used: If a feature log contains an external reference which is currently used by the part, this is indicated by an e in the icon, otherwise an a appears.(The property Use external references can be changed in the context menu of the feature log.)

External References
	Point option	Mid point or end point of an edge, centre point of a circle etc. Given, e.g., for positioning points of standard bores.
	Edge	For example, an edge which is filleted or rotated about a surface.
	Surface	For example, a surface which is rotated or to which a part is trimmed.
	Plane	The plane can be a real plane in a part, but also be defined via 3 points or 2 straight edges.

The symbol does not appear when generating the processing, but only after the first Feature recalculation.
