Drawing a Shielded Wire

Schematic
1

I am creating an aircraft schematic. When annotating the mic jacks and headphone jacks I need to show the wire is shielded. On other schematics I use it is a dotted circle around the wires to denote that they are shielded or gounded. Can this be done in KiCAD schematic? I have been learning the software for about 2 weeks now and really like its functionality for simple aircraft avionic applications.
Thank you in advance!

I believe you are trying to draw the airframe wiring diagram rather than an equipment schematic.

I’m not aware of a feature to draw a shielded wire, like coax. There is a lib symbol for a coax conn but you may need to create your own for shielded multi pin.

You can use the dashed line to draw shields, but that will be tedious.

This is from KiCad 6.0

Can you post an image (example) of what you are trying to draw? That would clarify the issue.

Oh very good. I did ever look for that!

@BobZ

Where is that window for “Line, Wire & Bus Properties”?

Select a line and press E. Or right click and select Edit Properties or something similar.

Thankyou.
I knew it could be accessed via Edit Text and Graphics in the Edit menu, but that way there is no box with examples of different lines, etc.
Never thought to hover then E over a line.
Now I just have to find the other eight ways to get to the same result :slightly_smiling_face:

There are 3*pi methods. (or is it pi^e methods?) I use a trackball with swapped buttons, so for me I select the wire and do a left click.

Folks,
I am trying to draw an airframe wiring schematic. So I am trying to replicate the outside shielded wire for grounding things in a radio schematic such as the phone/mic jacks. I will try to upload a pic of the schematic I am trying to replicate for our WWII fighter.

Around the Mic In and Phone GND you see the dashed lines. I may have to draw them in the symbol editor first, but since I am new at KiCAD I was wondering if this was already done somewhere.

Thanks all for replying!!
