DrawPad Pro.stl

DrawPad Pro.stl turns your 2D sketches into 3D-printable models right on iPad. Draw a shape, tap Extrude, and watch the canvas itself tilt into a live 3D view — then export a watertight binary .stl file ready for your slicer. Built for makers, not five-year-olds. A precise outline pen, shape snap for exact primitives, layered text in any system font, and a real polygon triangulator that handles holes through your model. Designed from the ground up for Apple Pencil on iPad. — SKETCH TO 3D — • Draw closed outlines with a precision pen built on PencilKit • Shape Snap auto-cleans rough freehand into exact rectangles, circles, triangles, stars, polygons and more • Insert Shape — stamp clean primitives (circle, square, triangle, pentagon, hexagon, octagon, star, heart) by dragging their bounding box on the canvas • Layers for stacking multiple outlines, each of which becomes a separate 3D body in the exported model • Mirror & Pattern tool with vertical, horizontal, four-way and radial symmetry (2–16 slices) — draw one cog tooth, get the whole cog • Bucket fill for coloring your 2D designs, without breaking the vector strokes underneath — REAL 3D EXTRUSION — • Tap Extrude and the canvas tilts into a live SceneKit 3D view • Scrub the height slider to change the extrusion depth in real time • Orbit the model freely with a drag — fully-lit, physically-based shading, no loading screens • Holes through the model: draw a cog outer and a circle for the axle and the extruder produces a hollow body, not a filled disc • Smooth cylindrical walls — adaptive segment count means round shapes render as real cylinders, not faceted prisms — 3D TEXT — • Drop in text boxes using any system font installed on your iPad • Glyphs are extruded as true 3D letters with correct holes in O, A, B, D, P, R — powered by SceneKit's glyph tessellator • Drag to reposition, two-finger edit content, pick from a searchable font picker with live preview — EXPORT STL — • Writes industry-standard binary STL files • Compatible with Cura, PrusaSlicer, Bambu Studio, OrcaSlicer and every mainstream 3D printer • Share directly to Files, AirDrop, email, or any installed slicer app • The geometry you see on screen is exactly what ends up in the file — PRO TOUCHES — • Built exclusively for iOS 16 and later on iPad and iPhone • Apple Pencil support with pressure-aware strokes and palm rejection • Autosave catches you if the app is swiped away mid-sketch • No subscription, no ads, no in-app purchases, no analytics, no tracking • Works completely offline — your designs never leave your device DrawPad Pro.stl is a one-time purchase. Your first 3D print starts with a sketch.
