Just trying to make some sense of dashed lines:
Found some dash methods here:

https://threejs.org/docs/#api/en/materials/LineDashedMaterial.scale

Stroke = the Line segment portion of a Dash.
Dash = Stroke plus Gap.

User adjustable Default values, where the size is an index of the length, to be determined:
dashSize = 3
gapSize = 1
So stroke would equal 2, and gap would equal 1.

The total number of Dashes: dashNum = 100. (Plus one final Stroke?) User adjustable.

??? Scale = 1 ???
LineWidth = 1. (Just regular line segment MoI width?) (Fatlines?)
LineCap choices: butt???, round, square. Might be relevant for Fatline dashes?

(And use the previously described Flow method to transfer to curved line)
A la chainmaker script.

FatLines script works for multiple curve segments.

Suggestion, Add LineCap choices to FatLines, (Fillet)

Here is a very good essay on "Data Visualization Using Lines, Dashes, Dots & Arrows".

It is for Canvas, but the ideas could be applied to NURBS, IMHO.

lineDashOffset property

Picture examples are given of LineCap properties Round, Square, and Butt.

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!
