Axialmark vs ModelLens

Axialmark is a high-performance 3D CAD and engineering model viewer for iPhone and iPad. With on-device geometry processing and Apple Metal rendering, Axialmark delivers precise inspection and fluid navigation for STEP assemblies, STL meshes, PLY point clouds, and other 3D engineering models. Whether you are in the workshop, preparing a client presentation, traveling, or working at your 3D printing desk, Axialmark helps you inspect and present 3D designs wherever you are. Key Features: • Precise CAD Geometry Inspect solid and surface models with clear feature edges and Hidden Line Removal (HLR) for technical viewing. • Metal-Accelerated Rendering Orbit, pan, and zoom through complex models with responsive, high-quality rendering. • Product Assembly Structure Tree Browse hierarchical assemblies, expand or collapse branches, isolate components, and see selections reflected in the viewport. • ViewCube and Camera Controls - Tap or drag the interactive ViewCube for standard orthographic and isometric views. - Switch between orthographic and perspective projection. - Use multi-touch orbit, pan, pinch-to-zoom, and Fit All framing. • Professional Display Styles Choose Shaded, Shaded with Edges, Wireframe, or Hidden Line Removal views. A reference grid supports spatial orientation. • Model Information Review bounding-box dimensions, triangle and face counts, file size, and unit information. • Private, On-Device Processing Open models from Files, iCloud Drive, AirDrop, and shared documents. Processing and rendering stay on your device. Supported Formats: - STEP / STP / STEPZ / STPZ - IGES / IGS - STL, PLY, OBJ - glTF / GLB - BREP, XCAF, VRML / WRL Download Axialmark to inspect, review, and present 3D engineering models on the go.

ModelLens is an offline 3D model viewer for iPhone and iPad. Open CAD parts, 3D-print meshes and scan point clouds the moment they arrive — no account, no upload, no network. WHY MODELLENS • 100% offline and private — no sign-in, no servers, no analytics, no tracking • Open models straight from Messages, Mail, WeChat, cloud drives or the Files app • Built for real-world sizes: smoothly loads 590k-triangle meshes and 500k-point clouds (performance varies by device) FORMATS • STL (ASCII & binary) — 3D printing meshes • STEP / STP — B-rep CAD geometry with adaptive tessellation and true topology edges (Open CASCADE kernel) • OBJ — meshes with materials • PLY — meshes and point clouds, including vertex colors FOUR RENDER MODES • Shaded — smooth solid surfaces • Wireframe — see the underlying structure • Shaded + Edges — surfaces with crisp feature edges: topological edges for CAD, triangle edges for meshes • X-Ray — translucent look-through COLORS THAT FIT YOU Seven macaron palettes (mint, matcha, peach, lemon, taro, sky, coral) drive both the interface and the 3D canvas, in light and dark mode. The default model material follows your theme. MODEL INSIGHT Live statistics: triangle and vertex counts, point counts, bounding-box dimensions, and format detection. BUILT ON OPEN SOURCE STEP support is powered by Open CASCADE (LGPL-2.1). License details are available in the app's About screen. ModelLens does not collect or transmit any data. What you open stays on your device.
