STP Viewer is an application which allows users to view 2D or 3D CAD models. Stl files as well as other formats.STP Viewer. The software has a user-friendly interface that makes it easy to view. Based on our own core, it provides quick import and export of the STL format, measuring and section tools. Try a brand-new STL viewer for macOS. 2D/3D Viewer CAD Viewer STEP Viewer SLDPRT Viewer Parasolid Viewer.
![]() .Stp Viewer Software Has ASTL files are used for 3D printing and additive manufacturing.A spreadsheet simplifies analyzing information from the STEP file at an entity and attribute level. In the spreadsheet, each entity type is a worksheet, each row is an entity instance where the columns are the entity attributes. Reports can be generated for PMI Representation, PMI Presentation, and Validation Properties based on Recommended Practices defined by the CAx Implementor Group. Nested assemblies are supported where one STEP file contains the assembly structure with external file references to individual assembly components that contain part geometry.Examples: Box assembly, Part with graphical dimensions and tolerances, AP242 tessellated part geometry, AP209 finite element analysis modelsThe viewer can also convert an ASCII STL file to STEP AP242 tessellated geometry. Compare the differences between STEP AP203 vs AP214 vs AP242.The free STEP File Viewer supports part shape, annotations for dimensions and tolerances, sketch geometry, supplemental geometry, datum targets, and finite element models that is displayed in a web browser. PMI consists of annotations and attributes that define product geometry and product specifications including annotations (callouts) to specify Geometric Dimensioning and Tolerancing (GD&T).STEP AP242, AP203, AP214 and others are supported. Validation properties are quantities related to features of a CAD model that are computed by the native CAD software used to validate the import of those quantities. STEP-File-Analyzer-sfa.xlsx - The spreadsheet was generated from an AP203 file that contains Validation Properties and PMI Presentation (also known as graphical PMI). PMI Representation is computer-interpretable to facilitate automated consumption by downstream applications for manufacturing, measurement, inspection, and other processes. Results are color-coded based on one of the NIST CAD models. PMI Representation includes all information necessary to represent GD&T without any graphical presentation elements. Creating a macos mojave vm for virtualbox mac hostThe Coverage Analysis worksheet shows coverage of PMI Representation concepts from the STEP file and CAx-IF Recommended Practices. Results are color-coded based on one of the NIST CAD models.The software includes a syntax checker that checks for basic syntax errors and warnings in the STEP file related to missing or extra attributes, incompatible and unresolved entity references, select value types, illegal and unexpected characters, and other problems with attributes. Syntax checking might help you diagnose errors when importing STEP files into CAD software. STEP file errors should be fixed to ensure that the file conforms to the STEP schema and can interoperate with other software. There are other validation rules defined by STEP schemas (where, uniqueness, and global rules, inverses, derived attributes, and aggregates) that are not checked.The CAx Interoperability Forum (CAx-IF) tests software implementations of AP242 and tested AP203 and AP214 in the past. The CAE Interoperability Forum (CAE-IF) tests software implementations of AP209. The CAx-IF and CAE-IF are joint testing activities between PDES, Inc. (U.S.), prostep ivip (Germany), and AFNeT (France).To test how well your CAD system implements STEP AP242 PMI, download the NIST PMI CAD models, open one of the models, export an AP242 file with PMI, and process it with the STEP File Analyzer and Viewer. The PMI Representation Summary worksheet will indicate how well the AP242 PMI matches the expected PMI in the NIST PMI CAD model test case definitions. Differences might be due to how some PMI was modeled in the CAD system or how the PMI was exported to the STEP file. The File Summary worksheet shows the distribution of STEP entities across all of the files. STEP-File-Analyzer-Coverage.xlsx - The spreadsheet was generated when processing multiple STEP AP242 files. PMI Presentation is not intended to be computer-interpretable and does not carry any representation information, although it can be linked to its corresponding PMI Representation.
