I have been fighting with this for some time now:
In a drawing that containes blocks with attributes, blocks with blocks with attributes AND xrefs with blocks with attributes. I need to extract some attributetags AND the X, Y and Z-coordinate. With ATTEXT and a filterfile I have got it working, BUT...
Sometimes the ATTEXT-file that is created displays some strange values in the coordinates. Sometimes numbers are very small or very large, but the XREF-drawing shows no entities on that coordinates. For example 3.277566e-99 of 4.19987e125. These numbers cannot be transferred and used for the rest of the program.
How can I fix this so it reads the real coordinates from the XREF/block and not some strange 'mutant'-code???
