Graphics and Annotations

Use schematic graphics and text to explain circuit intent, group related sections, and record design constraints. They support documentation but do not create an electrical connection unless the selected tool is explicitly electrical.

Choose the correct tool

Tool Use it for
Line, rectangle, circle, arc, polygon Visual grouping or explanatory shapes
Text Notes, limits, test points, and design intent
Harness Supported grouped connection notation
Junction Explicit electrical meeting point

Do not use a graphic line as a wire. If two pins must be electrically connected, use the Wire tool and verify the result with net highlighting or ERC.

Create and edit an annotation

  1. Select the graphic or text tool.
  2. Place its points or bounds on the sheet.
  3. Press Esc when the shape is complete.
  4. Select it and use Properties to set content, color, line width, fill, position, or size when available.
  5. Save and inspect the PDF result if the annotation is part of release documentation.

Video review needed

Record 15–20 seconds in v1.5.47 showing a text note and rectangle added, edited through Properties, then selected as ordinary graphic objects. Replace older media if tools or handles differ.

Annotation guidelines

  • State measurable constraints, not vague comments.
  • Keep notes outside symbol pins and wires.
  • Use consistent font size and restrained color.
  • Include voltage, current, tolerance, or test conditions when relevant.
  • Avoid duplicating information that is already controlled by a component property.
  • Confirm that release-critical notes remain readable in exported PDF.

Dimensions

Do not rely on a schematic dimension tool unless it is visible and verified in the release build. Record required distances as clear text or in the relevant PCB/mechanical workflow instead of documenting experimental or programmatic features.

Image — Documented schematic block

Image needed

Capture one functional block with a clean grouping shape and a concise constraint note. Keep electrical wires visually distinct from annotations.
