I am new to Qcad, so I don't know if I misunderstood something.
If you create a block with entities, then the entities in the block have their own layer and pen attributes. When you make a insert from that block on your drawing, the insert has it own properties (such as layer and pen attributes).
I have tried to change the attributes from the insert (other layer and/or pen attributes), but the insert always displays with the pen attributes from the block. Is this the normal behaviour or am I wrong? Can an insert be made with different properties than the block it is made from?
