Blocks, which layer to use?

[Husky]

Thanks Andrew - I think with this information I understand now how it currently works in QCAD.

However ...

You have to choose between using layer 0 or using the By Block approach for your block contents.

... after doing a little research regarding this topic in the www it seems to me that other programs don't have to chose between "Layer 0" and "By Block" - they can use both feature in the same block. It makes sense to me and I'm wondering why that isn't (for compatibility reason) is implemented the same way in QCAD Pro ...

Yes, that's what the preference "Layer 0 behaves differently" does.

What I meant is that you have to choose for your block contents, i.e. each entity inside your block if you want to use the layer 0 "magic" or use "By Block" attribute values.

I'm pretty sure the layer 0 behaviour is a backwards compatibility / legacy thing that was invented before there were "By Block" attribute values. Personally, I stick with the "By Block" attributes as I find that much more concise and deliberate.
