PolyWorks|Modeler vs Shapr3D

PolyWorks|Modeler is Windows desktop software that extracts CAD entities from polygonal models of digitized parts. It creates polygonal models from point clouds in real time and repairs geometry by filling holes, smoothing surfaces, cleaning boundaries, recovering sharp edges, and making surfaces watertight. Editing includes boundary extrusion, surface offsetting, fillet reconstruction, and Boolean operations with CAD models. A NURBS workflow combines interactive curve creation with automatic surfacing to produce editable CAD-friendly models. Users can create constrained parametric 2D sketches with arcs, lines, circles, and splines, then use listed import add-ins for CATIA V5-6, NX, Creo, Inventor, and SolidWorks. Supported polygonal formats include POL, PQK, JT, Nastran NAS, OBJ, PLY, STL, and VRML 2.0; CAD formats include IGES and STEP. NURBS surfaces export to IGES, JT, and STEP, while sketches export to PWSF or IGES. Windows 10 Pro or 11 Pro 64-bit is required, with an x64 quad-core CPU, 8 GB RAM, and a professional OpenGL card with 1 GB memory. Pricing is on request; a free demo is available by request.

Shapr3D is a 3D CAD application for direct and history-based parametric modeling. It has a built-in render engine and supports 3D-print export, while sculpting and animation tools are not included. The Free plan allows two projects and includes 20 generations. Pro costs $299/user/yr, billed annually and excluding VAT, and allows unlimited projects. Shapr3D runs natively on Windows, macOS, iPadOS and visionOS, works offline, saves designs locally and syncs them to Shapr3D Cloud when connected. It imports and exports native CAD formats, including XT, STEP, IGES, DWG, STL and 3MF. Browser-based Review Links let people view and comment on models, drawings and visualizations. Pro supports shared team projects, contributors, centralized storage and secure review links. Its 14-day Pro trial gives access to all features, but requires a credit card and charges on day 14 unless canceled at least 24 hours before. Listed requirements include Windows 10 version 2004 or later, macOS Sonoma 14.0 or later, and iPadOS 17 or later.
