New • Assembly is now part of modeling: create, move and edit parts in one place, with mates detected automatically • Move sketches in 3D by dragging the axes, or copy them; bodies built from them follow • Sketch ellipses; polygons are now one piece with editable side count, and even-sided ones show the across-flats size • One Import 3D File entry: bring files in as components or merge them into solids • Customizable modeling rails and interface colors • Projects are saved as encrypted .d3d files; older .mcad files still open Improved • Auto boolean: cuts when it overlaps, joins when it touches, new body when apart • Previews keep a translucent ghost of the original and tint only the faces that change • Adjacent fillets and chamfers follow when resizing holes or moving faces • Steadier sketch dimensions: no more flipping or jumping • Easier arrows in the Simple interface; tap one to type a value Fixed • Dragging dimensions on phones jumped and lagged behind your finger • Constraints lost after trimming or extending sketch curves • Some .3dm files crashed on open; some STEP circles showed as squares • Buttons squeezed in longer languages such as English

New • Replay steps: tap play at the top of the modeling tree and the model rebuilds itself step by step from scratch, with each step's new faces flashing briefly. Pause, step back and forth, set how long each step stays, and rotate the view at any time while it plays. • Synchronous modeling gains Copy face, Mirror face and Pattern face: a whole boss or hole moves as one piece and seats onto the body. Resize fillet gives a fillet face a new radius. • Command panels have an Apply button that does one step and keeps the panel and its settings open. • 3D annotations: view the annotations in STEP files and add your own. STEP and 3DM exports carry them, so they show up in other CAD software, and you can bring them into drawings. • The model tree gains layers, renaming and invert visibility; STEP export carries part names and layers, and STEP import reads layers. • In the Full interface, tap a face, edge or body and choose Edit to jump to the step that made it. • Sketch gains Slot, with five ways to draw it, and two picked points (centres, midpoints or line ends) can be made horizontal or vertical to each other. • In Simple modeling, tapping a face shows a smart dimension: thickness between parallel faces, hole or boss diameter, or fillet radius. • Plane grid in the display menu; new Rotation style (Free / Turntable) and edge pick range settings. Improved • On iPad, rotating the view follows your finger more closely and sketches open and close without dropping frames; dragging previews is smoother. • A softer selection glow; editing a model-tree step remembers more of its settings. • The built-in Camera sample has been updated and now includes 3D annotations. Fixed • A batch of shell and sweep fixes, a body flickering after confirming a command, stylus double taps not selecting a body, and top-bar filter labels squeezed out at larger font sizes. • On iOS 17, after dragging an arrow or slider, taps in the viewport stopped selecting and one-finger drags panned instead of rotating.

• Split body, trim body and mirror: clearer picking rules. The highlighted box decides what you can pick, the cutter and mirror plane options now sit in the box title, and the command no longer picks a face for you. • In booleans, a body hidden behind another body can now be picked. • The concave edge around the base of a cylindrical boss can now be picked. • Fixed subtracts failing on some older projects. • Rotating or scaling about a body's centre no longer shifts after the project is rebuilt. • Intersection curves and threads no longer modify the original body. • The fillet preview now respects the body's transparency. • 3D text is one step smaller in languages other than Chinese, so labels feel less cramped.
