DrawVibe vs Digit 3D CAD

DrawVibe is designed for architecture and interior design, integrating 2D layout planning and 3D spatial modeling into a unified workflow: you can quickly sketch freely in space just like drawing drafts, refining proportions and mass relationships. You can also use tools such as snapping, orthogonality, dimension marking and precise transformation to define key dimensions with high-precision controllable presentation. It supports free creative design in the early scheme stage, and in the final design stage, it can polish line drafts and models to a precision that is verifiable, renderable and convenient for construction communication, without frequent switching between different software tools. Core Functions ・2D & 3D Integration: Integrate layout planning and spatial modeling in one project; easily switch between top view / elevation / perspective anytime, reducing repeated file transfer between software. ・Freehand & Precision Balance: Support quick spatial sketching for scheme iteration; provide snapping, orthogonality, dimension marking and value editing to realize seamless transition from sketch model to precise model. ・Closed Area Fill with Brush: Fill patterns, proportions and gradient effects in closed areas to express pavement, zoning and conceptual color matching; filled content supports secondary editing and adjustment. ・Layer & Project Management: Classify and manage line drafts, fills and imported content via multi-layers; projects are fully saved in .rjproject format for backup and device migration, and files can be shared with colleagues for direct opening and continuous editing. ・CAD & 3D Asset Interoperability: Import DXF as 2D base drawings; export freehand lines and dimension markings to DXF for further editing and filing in common 2D CAD software. Support importing USDZ, OBJ models as scene decorations; export USDZ for further creation in other 3D design tools. ・Lighting & Material Rendering: Built-in lighting, material and camera angle functions to preview presentation rendering effects and greatly improve design efficiency. ・Lasso Quick Modeling: Use straight line / rectangle / circle / ellipse lasso to outline contours, extrude walls, plates and columns by setting height; support opening holes and special-shaped contour modeling. ・Dual Scenes of Plan & Elevation: The lasso tool can be flexibly used on ground or elevation working plane, realizing integrated workflow of 2D layout and elevation modeling design. ・Contour Extrusion for Special Shapes: Enclose any closed contour with polyline / lasso, extrude height along normal direction to quickly create buttress walls, bay windows, special-shaped columns and other forms. ・Elevation Molding & Line Profile: Directly extrude contours on elevation working plane to create cornices, line profiles, dado and other shapes; texture coordinates adapt to corner and narrow surface details. Import & Export ・Project Package（.rjproject）: Fully save all scene contents including lines, fills, layers, markings, models, lighting, etc., support cross-device migration; accessible via system files, AirDrop, email and other ways. ・Export CAD（DXF）: Export freehand lines and dimension markings as standard DXF files with coordinates adapted to common 2D CAD habits, convenient for secondary editing and filing. ・3D Model: Support importing USDZ, OBJ as scene decorations; support exporting USDZ for further design in other 3D tools.（Only import supported for OBJ, export not available.） ・Import CAD（DXF）: Select DXF floor plans and module materials as design base maps / references, synchronously saved and managed with freehand lines, 3D models and layer contents.

Digit 3D is parametric 3D CAD for iPhone and iPad: sketch, model, assemble and make drawings. Sketch • Lines, circles, arcs, splines, ellipses, polygons and slots, with dimensions and constraints • Mirror; linear, circular and along-curve patterns; trim, extend, chamfer and fillet • Apple Pencil support for precise drawing Model • Extrude, revolve, sweep, loft, shell, fillet, chamfer, hole, thread, pattern and mirror • Auto boolean: cuts when it overlaps, joins when it touches, new body when apart • Direct editing: move, rotate and copy faces, with adjacent fillets following along • Surfaces, 3D curves and 3D splines • Parametric history: edit any step at any time, and replay how the model was built Assembly and drawings • Assembly lives in the modeling workspace: new parts, move parts, auto-detected mates, clash check • 2D drawings with standard views, sections and dimensions; 3D annotations export with STEP Two interfaces • Full: every command, with customizable side rails • Simple: tap a face and drag the arrow, easy for beginners Files • Import STEP, IGES, STL, OBJ, 3MF, 3DM, Parasolid (X_T) and DXF drawings • Projects are saved as encrypted .d3d files Privacy Policy: https://digit3d.top/privacy.html Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
