Need help in creating a box around an actor

I am trying to do a selection box around a building, meaning that I want a box around some structure with lines, tried using collision box in blueprint went well but I need it to be other color and if possible the lines need little bigger.

Thanks for any help.

Never mind found a way to change the color in shape within the box, and just added my own box with cubes and changed the size of the cubes in the cunstructor event.
