Problem with blocks and part reference

[SamRol]

Hi,

     Im doing an aspiration pipe drawing.

In one file i have created severals blocks with straight pipes Blocks and bends Blocks... this will be my library of Aspiration blocks. 

Every one of this blocks have 2 part reference, for example, one Pipe Block has a part reference called PIPE and another called RING (used to connect pipes(.

The PROBLEM is that when I copy this blocks on another drawing SOMETIMES, SOME Part reference no work fine. The Auto tool not detect the part references, and looks that use onther reference empty

Please, could yuo help me?

I attach the library file, and the file where the BOM dont works fine.

Hi,

Some of the part references are in the different UCS from others so they cannot be detected. Part refs are still 2D objects in ACM. Suggest make them on the same UCS.
