IsBlock on Nested Blocks

[djnelson75]

Here is the issue I ran into, I am trying to find blocks that are nested inside other blocks. In the attached file blocks "Part 1" and "Part 2" are nested inside "SubAssembly 1". If I do the follow nothing is returned.

Block='SubAssembly 1'

BlkObj = rs.BlockObjects(Block)
for e in BlkObj:
    if rs.IsBlock(e);
     print (e)

but if I do this then it returns 4096 which are block objects.

BlkObj = rs.BlockObjects(Block)
for e in BlkObj:
     print (rs.ObjectType(e))

What am I missing here.

Hi Dennis,
I can see where this is confusing. There are two functions
IsBlock and IsBlockInstance
IsBlock refers to the single block definition in the definition table. IsBlockInstance refers to the individual RhinoObjects that point back at the instance definition.
