issue of importing dwg file

[ironwan7789-cyber]

Hello~
I'm using the provided functions well, but there's an issue when loading a specific DWG file.
I'm curious about the reason.
I've attached the problematic DWG file.

Hi @ironwan7789-cyber,

The file fails because there is a BookColor that doesn't follow the name structure which is "bookName$ColorName" I'll check if this is mandatory or it can be changed, if so, I'll open a branch to fix it.

Otherwise I'll see if I can find a solution for invalid color names.
