If you want to learn more about SVG syntax, an excellent place to start is. For example, Scheme-It wasn’t lining up my nets and terminals perfectly-so I just cleaned things up in Inkscape, and exported to PNG from there. If you’re having a hard time getting Scheme-It to do exactly what you need it to do, you could manually tweak your diagram by exporting it to SVG, and then editing in a tool like Inkscape or Adobe Illustrator. For example, when searching for capacitors, I was able to find 19 different symbols. It’s easy for me to add or omit labels for components, and find symbols that convey the appropriate level of detail for my diagram. Since it’s an EE-centric schematic tool, it’s pretty quick and easy to pull together circuit diagrams. One tool that I’ve had some success with is Digi-Key’s Scheme-It. If I’m drawing something for a report, article, or blog post, my focus is more on a presentation with a clean, professional look that doesn’t necessarily include details required to simulate or build the circuit. I’ve created schematics for a variety of reasons, and the tools I use depend on the type of schematics I’m drawing. Or, if you want to create a schematic for a published paper, you’ll need something polished, with the appropriate trade-off between detail and abstraction. If you need to create a schematic for a simulation, then the devil is in the details-you’ll need to be clear about power supplies, signal sources, component values, etc. If you’re just trying to convey a high level concept, a napkin schematic might do the trick.

When creating a schematic, it’s important to make sure you’re illustrating your circuit with the proper level of abstraction. A schematic usually omits all details that are not relevant to the information the schematic is intended to convey, and may add unrealistic elements that aid comprehension … In an electronic circuit diagram, the layout of the symbols may not resemble the layout in the circuit.” I like the definition of schematic in Wikipedia: “A schematic, or schematic diagram, is a representation of the elements of a system using abstract, graphic symbols rather than realistic pictures. Before you start learning Ohm’s law, superposition theorem, and delta-wye transforms, you need a basic understanding of how to read (and draw) a circuit schematic. One of the most essential skills for an electrical engineer is the ability to read and create schematics. There seems to be a limitless amount of information that can be learned in the field of electrical engineering. The Schematic Diagram: A Basic Element of Circuit Design
