layerling 1.74.0

• Snap grid: the dragged face lands on the grid: Dragging the height handle snapped the change of the height by whole grid steps, so a body 0.5 mm high on a 1 mm grid went to 1.5 mm. Now the face you drag (the top, or the bottom for the lower handle) lands on the grid of the workplane, so it goes to 1.0 mm, and the lift arrow puts the bottom of the body on the grid the same way. A tilted selection keeps the old step. Reported by @rondlh (#329).
• A double click on a slider sets it back to its default: The small arrow next to a changed value in a shape's settings was the only way back. Now a double click on the slider does the same, there and for seven sliders of the workspace settings (shadow strength and softness, the light's direction and height, shade contrast, overhang angle, zoom speed). The sliders of the small tool windows (edge tool, simplify, split) have no default to go back to and stay as they are. Suggested by @AD3DStuff (#361).
• The guide shows how to set an exact angle between two faces: There is no tool for it, but Align faces, then the rotation pivot on the edge where the faces meet and the angle typed in the Rotation card does it. The chapter on selecting and arranging now says so, in the section on laying flat on a face. Asked in #360.
• A new name in the STL export asks for a new file: In Chrome and Edge the first STL export asks where to save, and every later one writes into that file again. The file name field at the top of the export window then did nothing: a model and its liner exported one after the other with two names ended up in the same file. A name typed there that is neither the one the window started with nor the linked file's own now asks where to save, and the line under the window says so ("Asks where to save ..."). The guide says in the STL row that overlapping bodies are joined into one mesh in an STL, and that 3MF keeps them as parts. Reported by mail.
• Framing square: every number counts to the edge or the middle on its own: Beside each green number of the framing square sits a small switch, so a standing cylinder can be placed by its middle in the two arms and by its bottom in height, and a lying one by its middle across and an end along. The button at the handle still switches all three at once and shows the middle only when all three count to it. Typing a width, depth or height with the square follows the same switch. Suggested by DrJones in the forum.
• The height dimension stands outside the body: The height of a selected body was drawn through its middle, where its number sat on the shape. It now runs along the vertical edge that stands furthest right on the screen, with the number outside. Reported by DrJones in the forum.
• A cut that stays open says so: Cutting a part that has a gap-ridden surface - a STEP part whose mesh has a few cracks, say - gave a body that was open inside, because the clean cut refuses such a mesh and the fallback takes the material away without closing the cut face. The notice after grouping now says that the cut face is open, how many open edges the surface has, and that importing the part as STL or 3MF may give a closed mesh. Reported by @dsptech11-prog (#346).
• Align and Snap to Grid stand under Arrange: The two tools sat in the Modify group of the ribbon beside Chamfer, Fillet and Hollow, but they place a shape, they do not change it. They now head the Arrange group, next to Drop to workplane, Lay flat, Mate faces and Center on workplane, and take its colour; the command search lists them there as well. Nothing else moved. Suggested by @AkiraNorthstar (#357).
• The object list stays open: It started closed every time a design was opened or the page was loaded. Open or closed now stays as you left it, for every design, in this browser. Suggested by @grmonsey (#356).
• A revolve can be built from a line with a width: In a revolve sketch the Stroke button is back. Draw the wall of a vase or a cup as one open line to the left of the axis, tick the stroke and set the width: the revolve turns that band into a thin wall, as in Tinkercad. Closed outlines work too (a frame); what reaches across the axis is cut off at it. The body keeps the drawn line, so Edit sketch goes on from there. Suggested by @hlmodtech (#347).
• The lift arrow keeps its distance: On a thin body the arrow that lifts the selection sat only 2 mm above the middle handle, a few pixels on the screen, and covered it. It now stays at least 30 pixels away, whatever the zoom and the view. Reported by @Mycraftymama (#353).
• Russian: The whole interface, the 16 chapters of the guide and the guide's own pages are in Russian, with the language list and the guide's language switch. It is picked automatically for a browser set to Russian. Made by @CjCrash with an AI assistant (pull request #124); a second Russian reader is still welcome, wrong words are fixed with a small pull request. Along the way the guide builder learned two things any language profits from: a language without pictures of its own points at the English pictures instead of carrying a copy of them, and a heading in Cyrillic gets an id of its own instead of an empty one.
