MTEXT in dxf

[macbain]

I hope someone can help me with the dxf specification and requirements. I'm trying to use an MTEXT entity in a "manually" created dxf file. I have no problem with other basic entites (LINE, CIRCLE, TEXT, ...) but there seems to be some undocumented requirement(s) for MTEXT. I'm not using HEADER, CLASSES, TABLES, or anything that isn't required for basic entities mentioned above. Following is an example (which works fine as TEXT entity).

Thanks for your help.

 This is text in the MTEXT entity.

Never tried it but could you create some mtext in a drawing and dxf it out and see what gets output? I would assume something like text style definitions would need to reside in the file also.

Yes, thanks but I already tried that. Unfortunately there is a huge amount of "extra" info that also appears (HEADER, CLASSES, TABLES, ...). I call it "extra" because it isn't required for other entities (e.g., LINE, CIRCLE, TEXT, ..) In fact, some "extra" things like $ACADVER don't really even apply when I'm not creating it using acad.

I've tried to sort out the "extra" stuff before, but even with a simple LINE entity I found that you can't delete just some of it. Apparently the "extra" stuff isn't really extra; at least some of it is required.

Perhaps if I knew exactly what the minimum requirements are.
