Why these are called Reference Geometry? Most matching meaning in the dictionary is below. Is there any other meaning which is most suitable to SWX.
You've pulled up the verb meaning. This is a noun. It is geometry that does not actually exist in the solid/surface body, and is "referred to" by the entities that make up the actual geometry.
And just so you know, dictionaries do not always have the last word. If you want to call planes "whizbangcatchersurfaces", it really doesn't matter as long as others know what you mean.
