Hi, the attached DWG-file contains the layer "SITECO SL 11 micro 3000K" which contains inserts of blocks called "LP_SL11_mini". If I resolve DxfInsert.Block.Entities I get the following structure: block in layer "SITECO SL 11 micro 3000K" consists - block "LP_SL 11_mini" - layer "SITECO SL 11 mini 3000K" - block "LP_SL 11_mini" - layer "SITECO SL 11 mini 3000K" - circle - layer "SITECO SL 11 mini 3000K" - block "LP_SL 11_mini" - layer "SITECO SL 11 mini 3000K" - circle - layer "SITECO SL 11 mini 3000K" - circle - layer "SITECO SL 11 mini 3000K" Finally all of the circles have the same coordinate. But the block definition of "LP_SL11_mini" only contains one circle. Why does DxfInsert.Block.Entities contains two additional inserts of "LP_SL11_mini"? Is the object part of layer "SITECO SL 11 micro 3000K" or "SITECO SL 11 mini 3000K"? Or is CadLib misinterpreting something in the DWG file? Also if I open the file with TrueView it shows only one circle in layer "SITECO SL 11 mini 3000K". I'm using CadLib 4.0.30319. Best regards, Gerd

Forget my post. The file contains a block "LP_SL 11_mini", which only contains a circle and a second block ""LP_SL11_mini", which contains two "LP_SL 11_mini" and circle.
