SVG’s are the way to do it (they aren’t the only way to do it, but they are probably the best way).
You can copy this into a text file, save it as a .svg file and then drag it onto your view, this will give you a blank SVG.
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<svg
xmlns:svg="http://www.w3.org/2000/svg"
xmlns="http://www.w3.org/2000/svg"
width="50mm"
height="50mm"
viewBox="0 0 50 50"
version="1.1">
</svg>
From there it is just a matter of understanding how to work with SVG’s in general and in Ignition.
Here is an excellent resource for SVG’s - Pocket Guide to Writing SVG
This will allow you to understand what all the cryptic information in an SVG is actually doing and you’ll be writing (drawing?) you’re own SVG’s before you know it. Any thing that gets really complex it might be worth downloading an app like Inkscape, but for simple things understanding how to do it will make it pretty quick.
For instance if you want an svg with a line and a circle that can be done very easily. Drop in the blank svg, then add the following structure under the elements property:
The result will be this:
