Insert block and set the attribute，clone the entity and the style

[kjz1997]

Hello, first of all, I would like to insert a block into a layer that already has a DWG file and set its properties. How do I do this. Secondly, I want to copy other entities inside to another DWG file. How can I do this? I have traversed the entities and used clone, then written them into another DWG file. However, the text is garbled and all layers are incorrect. How can I ensure that the original attributes and styles of all entities are copied to another DWG file

Hi @kjz1997,

Any object in a document can be moved using the Clone() method, just clone the block added into the new doc and create an Insert from it.

For what you are describing the result should be fine, it seems that it may be an issue with the clone method, can you give some more details of the properties or differences between the entities?

For the text, is more complicated, if you are using special characters that may affect the re-write of the entities, are you using the package? there has been some PRs that help with that but they haven't been released yet.
