Create a custom shape

[Cosmic0921]

Hello! I recently found this, and I wanted to work on a project. I wanted to create a custom shape, and I followed the document, but I couldn't get an svg file to show up.

First, the circuit which is to be represented by a special shape is opened. Then an SVG template is created for this circuit.

I didn't get a template for this. Anything that I can do to get it to do this? Anything is appreaciated!
