About

Vexio3D

Read full description

Vexio3D is a focused 3D CAD modeling workspace for designing mechanical parts, sketches, solid models, prototypes, and printable objects on tablet, phone, and desktop. Create precise CAD sketches, shape 3D models, build solid geometry, and export files for fabrication or 3D printing. Vexio3D gives makers, students, engineers, hobbyists, and designers a practical CAD workflow for modeling parts directly on their device. Start with a sketch, turn it into a solid, refine the shape, organize the project, and export your model when it is ready. Vexio3D is built for hands-on 3D design, mechanical modeling, product ideas, brackets, fixtures, housings, gears, concept parts, and 3D printable components. Use Vexio3D to: - Create 2D CAD sketches with lines, rectangles, circles, arcs, trim, extend, offset, mirror, and constraints. - Shape 3D models from sketches using solid modeling tools. - Build solids with box, extrude, revolve, loft, sweep, fillet, chamfer, boolean tools, patterns, and more as supported by your device. - Design mechanical parts, brackets, fixtures, enclosures, gears, mounts, prototypes, and printable models. - Organize components, sketches, bodies, and modeling steps in a clear project browser and timeline. - Save and reopen Vexio3D project files. - Export OBJ and ASCII STL files for 3D printing, fabrication, and downstream modeling workflows. - Learn CAD modeling through guided tutorials and sample projects. Vexio3D supports a practical CAD workflow for people who want to model real shapes and parts. Sketch a profile, extrude it into a 3D solid, cut holes, add fillets or chamfers, combine bodies, and prepare the design for export. The app is designed to make CAD 3D modeling approachable while still giving you tools for structured mechanical design. Use it as a 3D model maker for functional parts, a CAD sketching tool for early ideas, or a compact solid modeling app for turning simple shapes into usable designs. Vexio3D helps you move from concept to geometry with tools that feel direct and focused. For 3D printing, Vexio3D helps you move from idea to model to export. Create printable shapes, check your design, save your work, and export STL or OBJ files for use with slicers, fabrication tools, or other 3D modeling workflows. It is useful for designing replacement parts, simple enclosures, workshop fixtures, mounts, hobby projects, and printable prototypes. For learning CAD, Vexio3D provides a clear path into sketch-based modeling. Tutorials and sample projects help you understand how sketches, constraints, solids, bodies, components, and timelines work together in a modern CAD workspace. Students and beginners can practice core 3D CAD concepts while experienced users can quickly build and edit part geometry. For makers and designers, Vexio3D is useful when you need to quickly shape a part, test a design idea, create a simple mechanical object, or build a model that can become a 3D print. It is designed for focused modeling sessions without unnecessary clutter. Vexio3D is a CAD and 3D modeling app for: - Mechanical part design - 3D printable models - Product concepts and prototypes - Sketch-based solid modeling - Parametric CAD workflows - STL and OBJ export - Maker projects - Engineering and design practice - CAD learning and tutorials - Shape modeling and object design - Tablet CAD and mobile CAD workflows - Hobby, workshop, classroom, and prototype design Whether you are learning CAD, designing a 3D printable part, shaping a mechanical idea, building a prototype, or creating models for fabrication, Vexio3D provides a focused workspace for CAD 3D modeling from sketch to solid to export. Vexio3D Pro removes ads and unlocks premium workflow limits and export capabilities. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Features
Read full description

Inspect CNC toolpaths and CAD models locally on your iPhone or iPad. Open files from Files, explore geometry in 3D and review machining programs without an account or cloud conversion. SLDPRT PART VIEWING • View SLDPRT parts in 3D, including saved solid bodies, surfaces and sketch curves. • Show or hide individual bodies and surfaces. • Rotate, pan and zoom, or switch between standard views. • CAD files are opened for viewing; the original CAD file is not modified. G-CODE REVIEW • Explore 3D toolpaths with axes, a grid and view presets. • Play back a program and adjust playback speed. • Review cutter names and diameters from CAM comments, tool numbers, feed rates, spindle speed and estimated run time. • Check X, Y and Z trajectory dimensions, including rapid moves. • Collapse the program information panel to make more room for the toolpath. • Edit feed and spindle values, then explicitly save the file or export a copy. CAD AND 3D MODELS • Open STEP, IGES, BREP and DXF exchange files. • Inspect mesh and scene formats including STL, OBJ, PLY, USD/USDZ, Alembic, DAE and SCN. • View model dimensions, geometry counts and available body information. • Additional previews are available for Parasolid, DWG and CDR, with partial format coverage. FILE COMPATIBILITY SLDPRT viewing uses geometry stored in the part file. Compatibility with native formats depends on the file version and available data. SLDASM assembly import is not supported. For unsupported files, export to STEP, IGES, STL or DXF in the authoring application. LOCAL WORKFLOW Selected files are processed on your device. No sign-in or upload to a conversion service is required. Privacy information and third-party licenses are available from the information button inside the app. Estimated CNC run time is an approximation. Review any edited program before using it on a machine.
