Every symbol instance was measured as its transform applied to the 20 × 20 square around the origin, which symbols made in the app keep their art in. The SVG and DXF importers keep symbol art as drawn, so the box of an instance of an imported symbol did not match its art. The SVG Star instance at x 20, y 30 draws from (20, 30) to (40, 50) and was measured from (10, 20) to (30, 40). Align moved such an instance by the wrong amount, clicks and marquees beside its art selected it, and the canvas, exports and prints left it out when its art reached the view or the page and the square did not. An instance is now measured by its symbol's art, which Document::symbol_boxes looks up in the document each time (Node::geometric_bounds_with, visual_bounds_with and reach_bounds_with). With Use Preview Bounds on, the strokes in the art count at their own weight, as the canvas draws them, and object.setBounds counts them at that weight when it sizes an instance or an object that holds one. When strokes do not scale and a width or height of 0 or more is smaller than what a path's stroke adds, object.setBounds now gives the path no width or height, as it does for an instance whose art has strokes; before, it mirrored the path. With Use Preview Bounds on, object.setBounds now measures the margins that strokes add object by object, the members of groups and the objects in symbol instances' art included, and solves for the width, height and reference point asked for when the width and height are 0 or more. Before, it measured the margins of the whole selection and could miss the size or the reference point asked for when strokes did not scale and the objects' strokes added different margins, and when strokes scaled and the width and height were out of proportion, even for one path. A clip group, a Shaper Group, a compound path, type, and a group or instance with effects or an opacity mask of its own are each measured as one object, and so is an instance in perspective or one turned or slanted relative to the bounding box, other than by quarter turns. When the selection holds more than 4,096 objects to measure this way, each selected object is measured as one. Instances inside symbol art are measured by their own symbol's art. An instance is measured as the square when its symbol is missing, when its symbol or a symbol nested in its art holds an instance of itself, and when symbols nest 32 deep in its art. Align and Distribute, the Transform panel, the bounding box and the selection outline, clicks, the marquee, document.inspect and document.node, Fit to Artwork Bounds and Fit to Selected Art, canvas culling, thumbnails, the SVG filter region of an instance with a raster effect, raster effect images, Export Selection, the SVG of an artboard, printing, and the PDF, EPS, EMF/WMF and DXF writers use the new box. The renderer also culls an instance by the effects and brushed strokes in its art, and it culls a blend, envelope or repeat by the brush art of what it holds and the effects in the art of the instances in it. It culls an instance with geometry effects of its own by the effects in its art after those geometry effects reshape the art. It measures the effects in a symbol's art once for each symbol and linear part of the transform that places it. For symbols whose art holds instances, it measures at most 4,096 placements a frame, and at most 4,096 more for each pattern tile it rasterizes and each placed document it draws. Past that, it estimates the reach from the symbol's reach with no transform, which it measures once. When the drawn document's symbols change, the renderer drops the cached bounds of the instances and of the objects that hold them. The PDF and EPS writers, the SVG of an artboard and Skip Blank Artboards grow the box of an instance whose art holds brushed strokes by 16 times the widest stroke (at least 1 pt) of the objects in that art that have a brushed stroke, plus 8 pt, as the renderer grows the cull bounds of a brushed path. They keep an instance whose brush art reaches the page. The SVG of an artboard also keeps an object that holds an instance when what the canvas paints for it, the effects in the symbol's art and the instance's own included, reaches the artboard. Not yet: other commands that measure objects, such as Select › All on Active Artboard, Transform Each and Convert to Artboards, still measure an instance by the square.
