layerling 1.152.1

• STEP import: a file the kernel gets stuck on says so (Discussion #286): A STEP file the CAD kernel could not read - a damaged one, written from a repaired STL - showed "Importing ..." for about half a minute and then nothing for two and a half minutes, until "The calculation took too long. Try fewer or simpler objects" came and went within seconds; whoever looked away saw nothing at all. The message of a STEP import now stays while the file is read, and when the kernel is stopped after 3 minutes it says that the file may be damaged and that importing the same model as STL usually works. A failed import's message stays until it is closed.

• Hover text follows a button's label (Discussion #1449): With LYL picked, the Export button read Save layerling design, but its hover text still said "Export STL". A button without a hover text of its own gets its label as one, but only once, so it kept the first. Now the hover text follows the label as it changes, and a part of the label kept hidden for another format no longer runs into it.

• Grouping or bundling with a locked part says why it does not work (Facebook): With a part locked by Ctrl+L in the selection, Group and Bundle only showed "Object locked", which did not say that the lock was the reason. The message now says that a locked part can't be grouped or bundled and names the two ways round it: unlock it with Ctrl+L, or lock only its shape with Ctrl+Shift+L, which a part can still be grouped with. In all 14 languages.

• Align faces: point to point (Discussion #1491): Align faces has a fourth way, Point to point. Click a point of the part that moves - a corner, a spot on an edge, the centre of a round edge or a reference point - then a point of another part or a reference point, and Align moves the part straight there without turning it. A dot shows which point the pointer would take; the two picked points stay marked in orange and green. Move along switches X, Y and Z on or off: only X and Y puts one point straight above or below the other, only Z brings it to the same height. After Align the panel stays open for up to two more pairs that turn the part instead, like aligning by three points: the first point stays put, marked in blue, and Turn swings the part about it until the line through a second point runs through the point picked on the other part; a third pair turns it about the line through both blue points until a third point faces its partner. Done ends it at any step, and each step is one Undo. layerling_mate_faces takes mode: "point" with point, targetPoint and axes, and point2/targetPoint2 and point3/targetPoint3 for the turns.

• Picking a face from below: the light-blue mark shows through the plate (Discussion #1492): A face behind the plate, such as the underside of a part lifted off it, never lit up while the pointer moved over it in Align faces, Lay flat or the hole pattern, nor when picking faces to delete or for a texture. The plate is see-through but held the mark back. Now the mark shows over the plate at full strength, and a solid part standing in front of the face still hides it.

• Lid, slide-in: a box set down turned takes one too (Discussion #1443, PR #1489): The slide-in lid worked the opening out square to the workplane's axes, so a box standing turned on the workplane, or a straight box with a hole turned by even a fraction of a degree, was refused as not a box. The lid now finds how far the opening stands turned and is worked out with the box turned back square; a turned box gets the grooves and lid a square one gets, and Slides in from picks the wall facing most nearly that way.

• Lid, slide-in: a frame above the lid (Discussion #1443, PR #1497): A slide-in lid always sat flush with the rim, and the wall it slid in through was cut down to the lid. The Lid panel now has Frame above the lid for Slide-in: at, say, 2 mm the lid and its grooves sit 2 mm below the rim, the walls keep their full height round it as a frame, and the wall it slides in through keeps its height too, with a slot just as tall as the lid that the lid's end fills flush with the outside. At 0 the lid is made as before. The box still prints upright, with only a short level bridge over the slot; the panel says when the frame leaves less than 1 mm of wall above it.

• Split, dovetail: no flaps on a part standing turned (Discussion #1451, PR #1494): On a box standing on its edge, the dovetail's tongue reaches a little into its own half below the cut, and where that half narrows towards the corners the ends of this foot stuck out as thin flaps half a millimetre thick. The foot is now trimmed to the half, so nothing hangs out. Reported by @makinglayerschannel, fixed by @marcus040473.

• Surface texture: pick faces for an image pressed on once too (Issue #1462, PR #1495): With Image as the texture and the picture pressed on once, the card hid the button for picking faces, although the image follows picked faces and the guide says so. The button is back. Reported by @MethylBromide, fixed by @marcus040473.

• European Portuguese: 2657 more texts (PR #1496): The European Portuguese translation covers 2657 more texts, and existing wording was brought in line. Contributed by @jcpcustodio.

• Japanese README (PR #1500): The project page has a Japanese README. Contributed by @eltociear.
