I have several drawings that were submitted to an outside party to make modifications. He used a program (LodeData, telecom mapping software) that created custom objects. Funny thing is they appear to be copies of the blocks I sent to him, only now with proxy data attached. Is there a way to remove the proxy data without removing the objects? I figure if EED or XDATA can be removed, the proxy data might be as well. I thought about writing a program to replace all the existing blocks in the drawing with blocks that don't have the custom data, but that seems cumbersome. Anyone have some code they can pass on?
