In general, Cura has a lot of these kind of "derived settings" where it's somewhat confusing which one is the actual setting and which is an awkward indirect way of setting it.

Wall thickness and line count in Cura, are they redundant, or do they multiply?

# Wall thickness and line count in Cura, are they redundant, or do they multiply?

(Asked by: username_0 on 2022-05-24)

I'm experimenting with larger nozzles and large objects. I thought I had left the default wall count at 3 and that's why the print was turning out much sturdier and much heavier than a smaller nozzle, even though it took 1/3 - 1/2 as long to print it.

Well, I have a 1 mm nozzle, `wall thickness` set to 2 mm, and `wall line count` at 2. I expected that `wall thickness` was to be multiplied by `wall line count` to arrive at the final wall width. However, I don't think that's the case, the two values seem to be interrelated and redundant. [This forum post](https://community.ultimaker.com/topic/25607-cura-360-understanding-wall-thickness/) from a few years ago tries to say as much. I now think that `wall thickness` is extrusion width (`line width`?) multiplied by `wall line count`.

The problem that I saw that made me dig into this, is that the `wall thickness` is set to double the line width, leading me to believe that I'm getting 2 walls of double-width walls, which means 4 mm thick walls. I don't think it's doing that, but I may have confused myself in the process. Looking at the line view, I think the walls are 2 mm.

How are these two variables related?

No, the `Wall Thickness` is the width of the complete wall, not of a single extrusion line, that is `Wall Line Width` which is a sub option of the `Line Width` property. Note that `Wall Line Width` itself is split up into `Outer Wall Line Width` and `Inner Wall(s) Line Width`

`Wall Thickness` is "`Line Width`" multiplied by the `Wall Line Count`

Note the `Wall Thickness` is calculated when you change the `Line Width`/`Wall Line Width` or greyed out, further more, when you set the wall width to a specified width, the amount of lines are calculated.
