A Bill of Materials (BOM) of part and assembly information can also be generated. Reports can be generated for PMI Representation, PMI Presentation, and Validation Properties based on Recommended Practices defined by the CAx Implementor Group. This research compares STEP, STL, and other 3D printing formats.Ī spreadsheet simplifies analyzing information from the STEP file at an entity and attribute level. In a spreadsheet, each entity type is a worksheet and each row is an entity instance where the columns are the entity attributes. The viewer can also be used convert STL files, that are used for additive manufacturing and 3D printing, into STEP AP242 tessellated part geometry. Cloud of points for geometric validation and Point clouds.Bracket assembly with Bill of Materials.Part with graphical annotations for geometric dimensioning and tolerancing (GD&T), including saved view viewpoints, datum targets and annotation placeholders.The STEP File Viewer displays many features of a STEP file in a web browser. Compare the differences between STEP AP203 vs AP214 vs AP242. STEP AP242, AP203, AP214 and others are supported. NIST has been involved with the development of STEP since the 1980's. PMI consists of annotations and attributes that define product geometry and product specifications including annotations to specify Geometric Dimensioning and Tolerancing (GD&T). STEP files are used to represent parts, assemblies, and Product and Manufacturing Information (PMI) that is used for data exchange and interoperability between Computer-Aided Design (CAD), Manufacturing (CAM), Analysis (CAE), and Inspection (CMM) software. STEP ( ISO 10303 –STandard for Exchange of Product model data) files are also known as Part 21 files with a file extension of. The Analyzer generates a spreadsheet of all entity and attribute information reports and analyzes any semantic PMI, graphical PMI, and validation properties for conformance to recommended practices and checks for basic STEP file format errors. And the practical side is that I can upload an item I need to be manufactured, and share it with the team, a machinist, or other departments.The free STEP File Viewer supports parts and assemblies, dimensions and tolerances, supplemental geometry, datum targets, and point clouds. It doesn’t require that you sign up with eMachineShop or even use their product or services. What it is, is free, simple viewing and sharing of 3D models, STEP files specifically. They do allow the option to ‘Delete from server’ or ‘Request Takedown’ but that is the extent of the protection. The STEP file can be downloaded by anyone, anywhere it is shared, whether you intend to or not. You can see many, many examples in their STEP File Viewer Gallery. Is it high quality? As you can see in my duct example above the surfaces are extremely tessellated for curved surfaces but machined parts look much better. You simply visit the site, upload your model (from your computer, Google Drive, Dropbox, or URL) and click Share to grab a link, QR Code, or embed code to share it with whomever you like. Now, they’re complementing their free product and paid services with a simple viewer that breaks the barrier of sharing 3D models quickly online.
