Ansys SpaceClaim vs ExtendSim

Ansys SpaceClaim is a Windows 3D modeling application for engineers who want direct modeling without learning a complex traditional CAD system. It can create, edit, repair, and simplify geometry, including CAD models prepared for simulation, and it supports assembly design, sheet-metal tools, and surface modeling. For reverse engineering, it can autosurface mesh data and convert STL geometry to CAD. Manufacturing workflows include model preparation, jig and fixture design, and sheet-metal design and unfolding. STL tools can repair faceted files and prepare models for 3D printing. SpaceClaim also provides bidirectional geometry linkage with Ansys Workbench. Import formats include .dsco, .sat, .sab, .asat, .asab, .pdf, .igs, .iges, .ipt, .iam, .msh, and .tgz; export includes .dwg, .dxf, .CATPart, .CATProduct, .cgns, .xls, .xlsx, .msh, and .tgf. It is paid, pricing is on request, and a 30-day Discovery trial includes SpaceClaim.

ExtendSim is process simulation software for decision-makers assessing improvement opportunities and system configurations. It supports customizable modeling logic, hierarchical subsystems, interactive user interfaces and exploration of design options. Features include reusable custom blocks, model hierarchies, simulation animation, 35 built-in distributions and statistical analysis tools. Data exchange options include Excel, ODBC and ADO databases, FTP and text files; Scenario Manager can export results to JMP or Minitab. ExtendSim Pro adds discrete-rate and reliability block diagramming capabilities to DE, while DE adds message-based discrete-event architecture to CP. It is a Windows application, with web also listed as a platform. Standard licenses require 64-bit Windows 10 or Windows 11; ARM configurations are not officially supported. Mac use requires installing Windows with an emulator such as Parallels or Boot Camp. The trial lasts 30 days from first launch and is limited to the downloader; it disables Multicore Analysis, watermarks models and cannot run on virtual machines. Individual license options are one-time purchases, with first-year Maintenance & Support included; CP costs $995, paid once, DE $3,495, paid once and Pro $4,995, paid once.
