hmmm, seems quite difficult to understand for me....

according to the wiki...
A Block is a group of entities. Blocks can be inserted into the same
graphic more than once with different Attributes and different locations,
scaling factors and rotation angles (see Figure 2). Such an instance of a
block is usually called an Insert. Inserts have attributes just like
entities and layers. An Entity that is part of an Insert can have its own
attributes or share the attributes of the Insert. Once created, Inserts are
still linked to the Block they instantiate. The power of inserts is, that
you can modify the Block once and all Inserts will be updated accordingly.

how can layers in a tree structure substitute this entity... (i thought
with a tree structure we could only achieve grouping objects)?

Message:
No need of block is needed for PythonCAD
The Layer structure of the program (Not olready present in the user
interface) will have a tree structure.
So with this tree structure you do not need the layer as in autocad.
As soon we will deliver the layer interface it will be more clear how it
works.

Matteo
