How to highlight a path in Calibre?

[[email protected]]

Hello,

I would like to highlight a path using Calibre? I have the DEF or
GDSII file, and list of nodes which makes a complete path from a FF/Q
to FF/D.

Can anyone would be kind enough to enlighten me for pressing the
appripriate buttons in Calibre for highlighting the complete path?
Thanks in advance. With kind regards?
