Aggregated entity layer conversion system and method

The invention relates to a two-dimensional graphic design system and method, in particular to an aggregate entity layer conversion system and method.

In the field of two-dimensional graphic design, some related primitives are combined into one whole, called an aggregate entity. Sometimes it is necessary to convert an already drawn aggregated entity from the original distributed source layer to the target layer. The conventional aggregated entity layer conversion method is that the designer searches for the primitives contained in the aggregated entity, and manually modifies the layers by the primitives included in the aggregated entity. For a complex aggregate entity, it is difficult to search all the primitives of the aggregated entity, and it is easy to miss the primitives in some aggregated entities, and it takes a lot of manpower and time to modify the layers one by one. If the layer is locked, the locked element layer must be unlocked before modifying the layer. After the modification, the unlocked layer is re-locked, which makes the operation more complicated.

In view of the above, it is necessary to provide an aggregated entity layer conversion system and method, which can quickly and easily convert the primitives contained in the aggregated entity from the source layer to the target layer.
