A 3D effect on a group built its solids from the members' paths and
paint and left out each member's opacity mask, and the mask of a group
inside the 3D group. Clipping groups, blends and symbol instances
resolved for the effect lost their masks the same way.
A member, or a group inside the 3D group, with an opacity mask now
gets a scope like one with its own opacity or blending mode, and the
mask goes on the group that holds that member's surfaces. Revolve
applies it with the member's opacity and blending mode; Extrude &
Bevel, Extrude & Bevel (Classic), Inflate and Rotate draw each solid
on its own when a mask is present and put the masked members' solids
in a group with the mask. A resolved clipping group, blend or symbol
instance keeps its mask. A disabled mask is ignored.
The check that refuses a symbol instance before its art is placed
counted only the symbol's own objects. Placing art through 9-slice
guides can make up to 28 objects of each one, and an instance's
dynamic-symbol overrides can turn a path that would be cut at the
guides into clip groups in every cell it reaches. Such an instance
passed the check, and its art was placed in full before the work
limit refused it.
The check now counts the symbol's own objects first, then the most
objects placing makes (NineSliceMap::most_placed) of the art with the
instance's overrides applied, and refuses the instance with the same
message before anything is placed.
A 3D effect on a symbol instance placed a copy of the symbol's whole art
before counting it against the effect's work limit, so a symbol far past
the limit was copied in full on every check and redraw before it was
refused. The symbol's objects are now counted first, and a symbol that
would pass the limit is refused with the same message without being
placed.
Inside a clipping group, the fills of a shape were cut into one piece in
the top fill's place. Rotate turns every fill, so with a fill, a stroke
and a fill, the lower fill was drawn above the stroke. With Rotate, each
fill now becomes its own piece in its own place. Extrude & Bevel, Inflate
and Revolve build from the top fill and keep one piece there, also when
an object changes from Rotate to another 3D type.
A clipping path nested past the depth limit, and a group at the limit
that holds further groups, are refused before they are walked, instead
of being followed to any depth. The clipping path's check follows the
members its outline is built from: the first member of a nested
clipping group and the shown members of other groups. The group check
skips hidden members and treats a compound path as one shape, as the
solid builder does.
An image in a clipping group whose bounds lie wholly outside the clipping
path's bounds draws nothing, so a 3D effect leaves it out instead of
refusing it. An image with effects, fills or strokes of its own, or one in
a group with effects inside the clipping group, is still refused, since
those can draw it inside the clip.
- When a group's geometry effects reshape its members inside a clipping
group, each member's piece goes back into groups with the opacity and
blending mode of the groups it was in.
- A clipped shape's pieces (its fills and each stroke) are counted against
the 4,096-object and work limits before they are cut.
- Resolving the symbol instances, blends and clipping groups a 3D effect
builds from counts every object it visits or makes and stops past
262,144 with an error. Nested symbol instances that end in hidden art
are refused instead of being expanded at every level. Each object is
visited once; a group is no longer walked again for each level above it.
- A symbol instance, blend or clipping group inside a 3D group keeps its
appearance, so its geometry effects reshape the art it shows. A nested
group's geometry effects now reshape its members inside a 3D group too,
and inside a clipping group they apply before the clip cuts the art.
- Hidden members and guides of a group inside a clipping group build no
solid.
- Tests cover an empty clipping group, a blend set to no steps, an
instance of an empty symbol, a symbol holding a clipping group, the
paint-copy budget across resolved art, and art past the limits drawing
as it does without the effect.
Extrude & Bevel, Extrude & Bevel (Classic), Inflate, Rotate and Revolve
now apply to a clipping group (or a layer with a clipping mask), a blend
or a symbol instance, alone or inside a group or layer. The solid is
built from the art the object shows: the art inside the clipping path
(fills cut to the clip, strokes as their outlines cut to the clip), the
blend's keys and steps, and the symbol's art where the instance places
it. Validation, the canvas, bounds, Expand Appearance, Rasterize and
assets.add3D read the same art from the document.
An image is refused, alone or in a group, with a message to trace it
first with Object > Image Trace > Make. A missing symbol, a symbol that
holds an instance of itself, art nested more than 64 levels deep and
more than 4,096 objects are refused. The refusal messages change, and
their rows change in every catalog.
