The panel's Trap is one undo step and groups the traps above the topmost selected object, selected; with no adjoining edges of different colours it says so and changes nothing.

   - Effect › Path › Outline Object has no options. Type that carries it is drawn, exported (PDF and SVG as paths, with no font) and expanded as its glyph outlines while it stays editable, and the effects after it reshape those outlines. Paths and images draw as before. With Use Preview Bounds on, type is measured by its glyph outlines. Public reference: [Summary of effects](https://web.archive.org/web/20210901011839/https://helpx.adobe.com/illustrator/using/summary-effects.html) (archived copy).
   - With Use Preview Bounds on, the bounding box, the Transform panel, Align, Distribute, Distribute Spacing and `object.setBounds` measure each object after its geometry effects. A path is measured by its effected shape, and a fill or stroke with geometry effects of its own is measured by the shape it paints. Type, images, live objects and symbol instances are measured by their reshaped art, and a symbol instance is also measured by its reshaped art when its symbol's art has geometry effects. A group or layer with geometry or Pathfinder effects, or with a fill or stroke of its own that has geometry effects or paints members with geometry effects, is measured by its evaluated art. A blend, envelope or repeat whose objects have geometry effects is measured by its evaluated art, with those objects measured after their effects. A 100 pt square without a stroke, with Offset Path 10, measures 120 pt, and type with Outline Object aligns and sizes by its glyphs. Raster effects are not measured.

Cap is on by default with continuous curved vector rims; shading uses vector gradients automatically, with sharp profile corners, uniform caps and round seam joins. One light and approximate visibility remain ([revolve.md](revolve.md)).
