  How to make Null follow edge of text?

  Posted by Kevin Hickey on January 19, 2021 at 5:11 pm

  Hello

  I’m trying to make nulls follow the edge of a text box, based on the characters within.

  I have the following set up, where the left and right edges of the text box follow the corresponding nulls (using Path follows Nulls). I’m now trying to set up the position of the nulls so that they react to the left and right most sides of the Text layer, so that whatever the City location in the text box, the background layer’s width responds.

  I know the answer will be to do with expressions, can anyone help me figure out the solution to this?

  Thanks!
