Dynamic Block - Getting it Right!

I am trying to get this block to be dynamic where the cut moves fro the center making the two cut lines equal on either side. What am I doing wrong? I've tried all combinations and can't figure it out. Can someone help...thanks!

Try it with a "linear stretch pair" whose linear parameter runs the entire length of the break symbol (from one end to the other).  The basepoint of this parameter should be set to Midpoint.  You will have two stretch actions associated with that parameter.  One will stretch the upper point, the other will stretch the lower point.  On the one you want to be the "master" stretch, set the Distance Multiplier property to -1.

Have fun.

I don't think I am understanding exactly.

I did a linear parameter.

Created the action to stretch from top to mid of line below cut symbol.

Set the dynamic properties to midpoint.

Dist. multplier does not allow -1 unless I was in the wrong area.

 

Need assistance again. thanks!

Here's a demo, (although different than what was previously described.)
