Walkthrough

The icon design guide was reorganized. It now combines design and style rules, defines monochromatic coloring, and documents updated SVG export and release processes.

Icon design guidelines

Layer / File(s) Summary
Design and style guidance
docs/icons/design-new-icons.md
The guide revises the checklist, color guidance, design-grid structure, clearance exceptions, stroke and fill rules, spacing rules, and filled-variant naming.
Export and release requirements

The guide adds 24×24 SVG specifications, required SVG attributes, and separate internal and project-specific release processes.

Icon authors could produce inconsistent SVG dimensions or misapply the gap rule, but the impact is bounded to documentation clarity and can be corrected locally.

- Line 32: Update the documentation sentences around the icon runtime-coloring
description, the Siemens application guideline, and the title-element warning to
use explicit subjects and active voice, preserving their original meaning.
- Line 47: Update the icon documentation prose to replace curly quotation marks
with straight double quotes around the referenced terms, including “Icon Design
Grid,” “N,” and “No,” while preserving the existing wording.
- Line 24: Update the icon design checklist recommendations, including the item
beginning “Do not create alternatives…”, to use suggestion-oriented “we
recommend” phrasing instead of direct imperatives. Apply the same wording style
to the related checklist items.
- Line 114: Clarify the strike-through spacing guidance in the icon design
documentation by explicitly stating that the 2px gap appears above and to the
right of the diagonal strike-through.
- Line 130: Update the exported SVG requirements in the design-new-icons
documentation to specify exact attribute values: viewBox="0 0 24 24",
width="24", and height="24".
- Line 124: Remove the Oxford commas from the checklist lines describing icon
names, including the lines around “Short, descriptive, and unique icon name” and
the additional referenced checklist entries. Preserve the wording and
punctuation that is not part of the comma-before-“and” or “or” construction.
- Line 107: Update the guidance in design-new-icons.md to define the unsafe gap
pattern precisely, explicitly describing alternating 1px gaps with no gaps
instead of using the vague “set pixel and no pixel” wording.
- Line 138: Update the release-process step describing creation of the GitHub
change request to use “pull request (PR)” instead of “merge request (MR)”.

A few changes. We try not to use "exist" as this is such a uncommon word in English. Also we don't need the ( ) for e.g. And I'm not sure about the periods ( full stops) here. Usually a sentence needs it. Short cut words or lists not. And for iX we dont use periods for dos and don;ts. Either way, it should be the same for one page.

- We recommend using more generic icons instead of creating multiple very specific new ones (e.g., use the generic "add" icon instead of creating an "add-wireless-device" icon)

- Do not create alternatives to existing icons just for the sake of your own look
- Do not create alternatives to existing icons just for the sake of your own taste

Hmm, we had already some iterations on that phrase. And we used this one now, because some designers could say: "Hey, I have a reason to create an alternative, because the existing icon looks ugly." We want to avoid designers use this explanation as excuse to create their own alternative icon set just to look different.
Is there another way to say this?

- In Figma, all layout constraints are set to "Scale" and resizing behavior is tested
- Before you export, set the icon color to #000 to ensure proper visibility in typical SVG preview tools
- The exported SVG must contain viewBox, width and height (24×24)
- The exported SVG must not contain a `<title>` element. It can cause unintended browser tooltips.

@tokyojen, I explicitly used "must not" in terms of "darf nicht enthalten sein". Because some SVG export tools automatically integrate the <title> in the SVG code and this triggers unintentionally tooltips when mouse hovers these icons.
That means in practice, an exported SVG, e.g. from Adobe Illustrator, could contain the <title> but it "strongly" should not.
Is "cannot" then still correct?

Clarify the dimensions for custom icons.

The general requirements apply to the custom or project-specific icon workflow and require exported SVGs to use 24×24. The external icon workflow requires 512×512 for width, height and viewBox. Document whether custom SVGs must be resized or re-exported to 512×512 before handoff to developers.
