This drawing originated in 1998, trying to update it.  Stuck in 1.5" line width, for dogleg, line or cable tool.  Tried modifying different lines, unlocked document, turned off snaps, turned of ortho, changed layers, closed and reopened.... giving up on this drawing for today.  Wasted an hour. 

This problem seems tied to this series of drawings.

Any ideas?

Thanks,

Linda
