   - Extrude & Bevel (both kinds) and Rotate keep the art's curves in the faces they draw, export and expand: caps and the edges of walls and bevels where they meet a cap are cubics with smooth anchors where the art's are, fitted within 0.001 pt in perspective and within the sampling tolerance on a bevel's inset. An edge of a twisted wall that is cut into pieces, a piece of curve that does not fit after 8 halvings, and the curves past 1,048,576 for one solid stay straight (VectorCraft's own values; [three-d.md](three-d.md#what-differs-from-the-public-documentation)). Tests `solid::tests::a_cap_keeps_the_curves_of_the_art`, `a_cap_in_perspective_fits_the_projected_curves`, `a_beveled_cap_and_its_walls_share_their_curves`, `twisted_beveled_tiny_and_degenerate_caps_keep_their_curves`.
   - Export 3D Object (Asset Export's menu): an object with Extrude & Bevel, Revolve, Inflate or Rotate becomes a 3D asset whose Format is USDA (the default), USDZ, glTF or OBJ, and Export writes each of its solids as a mesh with a material in its paint's color (`assets.add3D`, `assets.set3DFormat`, `assets.export3D`; [export 3D vector artwork](https://helpx.adobe.com/illustrator/desktop/special-effects-styles/create-3d-graphics/export-3d-vector-artwork.html)).
   - Export 3D Object builds each Extrude & Bevel (both kinds) and Inflate solid once: the same build gives the faces that count toward the object's limit and the faces of its mesh, and the meshes match those of a separate build bit for bit. Tests `mesh::tests::a_meshed_solid_is_built_once`, `an_extruded_solid_and_its_mesh_match_the_two_built_apart`, `inflated_solids_and_their_meshes_match_the_two_built_apart`, `solids::tests_mesh::one_build_exports_the_meshes_built_apart`, `a_stroke_past_the_limits_is_left_out_of_the_export`.
+  - Checking an Extrude & Bevel (both kinds) or Inflate effect builds each solid the effect draws once, about the bounds the effect draws it about; a shape with no fill still has its profile built on its own. Tests `solids::tests::the_check_builds_each_drawn_solid_once`, `the_check_builds_the_profile_of_a_shape_with_no_fill`.
   - Initial live Revolve (#605, #846): a portable geometry and shading crate (`three-d`), editable path and compound profiles, compact options with artboard rotation and light gizmos, SVG/PDF vector output and Expand Appearance that can trim covered faces. Open ends have continuous caps by default, shading is smooth with one to ten colored lights, and intersecting surfaces' visibility is approximate ([revolve.md](revolve.md)).
   - Revolve takes graphics on its swept side, shaded with the object's light ([the archived reference, page 185](https://web.archive.org/web/20210601162814/https://helpx.adobe.com/pdf/illustrator_reference.pdf#page=185)). By VectorCraft's own rule a graphic wraps around the axis at its own size at every distance from it, narrows toward the silhouette, follows the profile along its length and is hidden where the side faces away (`threeD.mapGraphic`; `revolve::tests_graphics`, `tests::side_faces_lie_on_the_unrolled_surface_and_caps_do_not`, `map_graphic_puts_a_graphic_on_the_side_of_a_revolve`).
   - Revolve takes type, as its glyph outlines, and groups or layers, whose members sweep about one axis as [the help page](https://helpx.adobe.com/illustrator/desktop/special-effects-styles/create-3d-graphics/create-3d-objects.html) describes; a surface can have up to 16,384 profile points, and curves take fewer samples when a surface would pass 163,840 faces (#3617).
