MicroStation has a lot of styles for elements: Element Templates, Text Styles, etc..
Due to the style is also a property of the element in the Properties palette but the user which is ultimately can override values then maybe the properties of that style are not applied fully, so there is not full match between properties of the element and the applied style.
This happens for example with Element Templates (Template) property and later the user changes a color or a Text Style and then the user changes the Height from the properties.
So "Full Match" should be a property of any element which has a style.
Full Match property should appear in the Properties palette under the style property.
AutoCAD does not have this either and should have it anyway.
MicroStation has in some cases the property Modified (Text, Level Manager,..) but this is between the local style and its DGN Library comparison.
I have seen that "Text Editor" has a "Revert Style" button.
It is disabled when has "Full Match" (show a gray icon)
and it is enabled when there is not full match. (show a colored icon). If we press this button then applies the properties of the style. It would be if we select again that style in the properties palette.
So the idea would be that MicroStation had a "Revert Style" button next to the Style property in the Properties Palette (show image).
Such as "Text Style" for text elements, "Dimension Style" for dimension elements...
Also "Template" property had a "Revert Style" in the Properties Palette.
