Does anyone know anything about what the purpose of this is? How does it work? I get some really odd results with it.
I use it for multiple stretch actions. Lets say you have some lines... you want to stretch some of those line to the left and at the same time you want to stretch some of those lines up but only half the distance of the the one to the left.
Sooooo...
You add a linear parm. to each set. The upper set you will turn off grips and turn on chain action...and set the distance multiplier to 0.5
The left set set the grip to 1
Now you add a stretch action the the upper lines...
Next add a stretch action to the left line, after selecting those lines with the bounding box select the upper stretch and the upper linear parm.
Save the block.
when you insert that block and use the left grip stretch, the upper line will now stretch 1/2 the distance upward.
I use it for urethane headpieces. I have the insertion point in the center and when I stretch one side, the other side stretches in the opposite direction.
I believe that the main purpose for it is so that you can do multiple actions at once, based from one single action... Clear as mud??
Here is an example of a head piece.
