Hi, You're right, the method was a little to simplistic. I've added method DxfInsertBase.ApplyBasicBlockInsertionTransformationToAttributes which applies the complete BasicBlockInsertionTransformation to each attribute. - Wout

Thanks Wout. After a lot of hair pulling, I finally got it merged and working with our code base. I was losing my mind with really odd behaviour in the production code versus the snippets posted here. Eventually I figured out that our production code, deep down, was using the parameterless "new DxfModel()" constructor which defaults to DxfVersion.27. But this produces entirely different results for the multilines than DxfVersion.32. I assume this is because v27 of the DXF specification doesn't support them, eh? Anyway, thanks for all your work bouncing this back and forth. Glad to finally have it working.

Hi, Yes, R27 doesn't support multiline attributes indeed. I'll change the DxfModel constructor to default to R32 in the next version, that makes more sense. - Wout
