Objekte mit ungültigem Symboltyp

Invalid symbol type means that an objects is assigned to a symbol but object and symbol types are different.

Objects with invalid symbol type are display gray.

An invalid symbol type can occur for example if you change symbol sets of a map. If the new symbol has the same symbol number as the old one but the symbol type is different (e.g. an area symbol instead of a point symbol), OCAD cannot display corresponding point objects on the map anymore.

Or objects with invalid symbol type can occur if you delete a symbol (e.g. a line symbol) which is used on the map and then create a new symbol of different type (e.g. a point symbol) with the same symbol number.
