calculate area of a block refere..if not possible can we get vertices of block

Hi,

I am very new to programming autocad through .net.

Question : Is it possible to compute area of a block reference.If we are not able to get the area directly

may be through coordinate system will use the below formula to compute the area

In order to use the above formula..i should get all the vertices of the block reference..

can any explain,any of the above specified things is possible..

Hi,

Basically, a block reference is a transformed geometric representation of a block definition inserted in some space (or another block definition).

A block definition is a collection of entites, which may or may not not have an "area".

So, the" area of a block reference" does not make sense.

The area of some entity (or entities) contained in the block definition can be computed.
