Linear Stretch in opposite directions

[Anonymous]

I have a block where I want to stretch the base of it in one direction and have the other side stretch in the opposite direction an equal distance.  I've tried adding a second stretch to it with a distance multiplier of -1.0.  Doesn't seem to work.

How can I get the base linear stretch to also go in the opposite direction on the opposite side.  ACAD file is attached.

Thanks!!

The following screencast shows how to get it working in a couple different ways.  When adding linear parameters that will only have one grip, add the non-moving point first and add the point you would like to move with the grip second.  Be sure to select the correct point to associate with the action.

You're so close to what you want.

Instead of a negative multiplier value look to the next cell down in the action properties, Angle Offset.  Set the angle to 180 to have the action go in the opposite direction of the parameter.

Actually that isn't the issue with their block.  The issue is that they included the left polyline in the selection set for both stretch actions.  With their current selection sets, it will not work correctly with a 180° angle offset or a -1 distance modifier.  If the selection sets are assigned correctly, then the block will work correctly with EITHER a -1 distance multiplier OR a 180° angle offset.
