Sketch an idea in 3D, shape it with precise CAD tools, and see a photorealistic render update beside it as you work. uMake is the 3D design app for architects, interior designers and product designers, on iPad, iPhone and Mac. NEW IN UMAKE 10 • AI Design Partner: describe a vase, a mug or a room with furniture, or give it a reference image, and it builds an editable 3D model on your canvas. Keep refining in plain words. • Floor plans: give the Design Partner a plan image, and it builds it in 3D, up to three stories with stairs. • Live AI Preview: a photorealistic render sits beside your model and updates after each change. Switch its look, place your model in a photo, or render four views at once. • Scene Studio uses AI to turn a picture into a short film, one change at a time. Move the camera, set the time of day or recolor the sofa, and each change becomes a short clip. • Flows: connect AI cards such as Sketch to render to a picture. Change the picture, and one tap updates every result. SKETCH AND MODEL IN 3D • Three ways to draw: Precision for exact lines and arcs, Pen for one smooth curve, Freestyle for loose strokes in 3D space. • Draw on a sketch plane or right on a model’s surface. • Lift curves into NURBS surfaces and reshape them by their control points. • Extrude, Push & Pull, Revolve, Loft, Extrude Along Path, Mirror, Array, Offset, Fillet & Chamfer. • Combine: union, subtract or intersect solids, with a 3D preview before you apply. • Project Shape wraps a logo, grille or pattern onto a curved surface. • Component: change one copy, and every linked copy follows. • Mesh Editing: fix imported or AI-made meshes by face, edge or vertex. • Dimensions in real units: mm, cm, m, inches and feet. • Apple Pencil Mode on iPad: Apple Pencil draws while one finger orbits the view. SPACES: ONE BOARD FOR THE WHOLE PROJECT • An infinite board for sketches, notes, photos, videos and live 3D designs. • Layers and layer groups, with an underlay for tracing a plan or a photo. • AI tools work on what you select: Compose a Scene, Variations, Apply Style, Save as Style, Presentation Set, and Split into Layers with Make Whole. • Turn a photo into a 3D model. • Generate images, color palettes, textures and short videos from a description. RENDER, PRESENT AND SHARE • Render with soft shadows, sun studies by time of day and season, and styles like Architectural Clay, Technical Ink and Blueprint. • PBR materials with roughness, metallic and emissive controls. • View in AR places your design on a real table or wall, on iPhone and iPad. • Present with Slides and Full Screen, and write notes over a slide with Markup Mode. WORKS WITH YOUR FILES • Import OBJ, STL, STEP, IGES, USDZ, GLB, DAE, SketchUp (SKP) and SVG. • With a plan, export STEP and IGES for CAD, STL and OBJ for 3D printing, USDZ for AR, and Hi-Res PNG. • Sketching and modeling work offline. A free account backs up and syncs your designs. MADE FOR HOW YOU WORK • One app for iPad, iPhone and Mac with Apple silicon. • Supports iPhone Duo: open the phone, and you get the iPad workspace. • 14 languages. • 2015 iPad Pro App of the Year, Best of App Store 2015, Editors’ Choice.
