I made a simple node to automate converting curves/lines to dashed lines.
open Nodeeditor => load attached node => select lines => update "Selected" node => run

Here's another node method

In the end I trimmed the lines to get things going...time consuming...
I am going to try the node editor as I did not use it yet for anything...

Attached a pic for the way to change it in Pepkura...fast...Change from solid line to dashed and or options.

Tnx!
