Issue:

When inserting a drawing file as an external reference in ZWCAD, the command line prompts: ** Error: "XXX" is already a standard block in the current drawing. *Invalid*, and the external reference cannot be inserted.

How to insert this external reference file?

Solution:

This is because the file name of the external reference is the same as the standard block name in the current drawing.

The external reference is inserted into the current drawing as a block in ZWCAD. Blocks and external references have many similarities. They can be edited with in-place editing(REFEDIT) and can be clipped with XCLIP(XC). Because of the many similarities between them, blocks and external references cannot have the same name. If a block exists first, an external reference with the same name cannot be inserted.

Solution: Rename the drawing of the external reference, or rename the block in the current drawing.

The command to rename the block is RENAME.
