I am a Autocad NOOB. I have been using it for a long time. just haven't really used any of the power under the hood.I only use about 25 different blocks over the last 7 or 8 years. I am an electrical geek so the only thing that changes is the arrangement of the blocks. I have tried to build a block that makes things a lot quicker. There is 17 Tags that all need the same value. I might use this same block 30 times in a drawing. The first block would be M1, the second M2, Third M3, etc,etc.  Is ther a way to link tag values to 1 master tag in a block?Please be patient with me I am just starting to explore the power of this software. Using Autocad 2014.Win 7 64 Pro virtualized.
