1 edition of CAD Geometry Data Exchange Using STEP found in the catalog.
With increasing demand for data exchange in computer integrated manufacturing, a neutral connection between dissimilar systems is needed. After a few national and European attempts, a worldwide standardization of product data has been developed. Standard ISO 10303 (STEP - STandard forExchange of Product data) produced in its first version those parts that arerelevant for CAD geometrical data. A European consortium of 14 CAD vendors and users was supported by the ESPRIT programme to influence the emerging standard and implement early applications for it. Over the years 1989-1992, project CADEX (CAD geometry data EXchange) worked out application protocols as a contribution to STEP; developed a software toolkit that reads, writes, and manipulates STEP data; and, based on this toolkit, implemented data exchange processors for ten different CAD and FEA systems. This book reports the work done in project CADEX and describes all its results in detail.

To create a "smart" product involves a lot more than simply slapping together some sensors on a physical product. It takes knowledge of the product, different mechanisms that actuate it, engineering behind it, sound understanding of manufacturing failure modes, electronics, sensor selection and placement, embedded systems, software and so much more. I want to access general geometry data from previously created step files. How do I access this information without using ion? I would want to return geometry data such as volume, edge line coordinates as well as vertex intersection coordinates. Is this possible to do, and in that case how? Now I have attempted: FreeCADGui.
The Wolfram Language supports import and export of 3D geometry from all standard formats\[LongDash]with its symbolic representation of 3D objects allowing immediate faithful interchange. Once the CAD Data is in a geodatabase you can always export the feature class to a shapefile, just know that if your CAD line work has curves in it you will lose some curve data converting it to a shape file. This is because an advantage to geodatabases is that they store mathematical s: 3.
How to deal with cad-geometry In general hexahedra-elements perform better than tets but if the mesh should be derived from a cad-geometry it is often more convenient to create a tetrahedra mesh as to modify or rebuild the geometry to make it meshable with hexahedra-elements. The following section gives some hints which alternatives are available. CAD SEEK is an innovative technology that captures the geometry of CAD and other digital shapes in a form that is both accurate and readily comparable. Imagine being able to classify an entire CAD database by shape automatically, and being able to search simply by selecting one model to find all others like it without worry about synonyms or.

The Product Data Technology Advisory Group, short PDTAG, was established on 30 September under the auspices of the ESPRIT CIME Division of the Directorate General XIII of the European Commission. Its goals include promoting European cooperation and improving the European infrastructure in CAD Geometry Data Exchange Using STEP.

Over the yearsproject CADEX (CAD geometry data EXchange) worked out application protocols as a contribution to STEP, developed a software toolkit that reads, writes, and manipulates STEP data, and, based on this toolkit, implemented data Cited by: CAD data exchange is a modality of data exchange used to translate data between different Computer-aided design authoring systems or between CAD and other downstream CAx systems.
Many companies use different CAD systems internally and exchange CAD data with suppliers, customers and subcontractors. Transfer of data is necessary so that, for example, one organization can be.
This assures that the translated geometry and PMI data is the same as the native geometry was. In addition, CADIQ can be used as a component in DEXcenter, which automates data exchange through a Web interface.
(See figure 5.). The STEP file format  also clearly presents the geometric feature data in a structured manner that is easy to interface with. The STEP data model for each part of the standard conforms to a.
STEP method still loses some data related to design intent. A well-known issue of STEP method is that this method is limited to exchange product geometry, where those nongeometric data related to.
Smart object snapping tool to capture geometry shape's vertex, edge, edge center, edge quadrant and face center. Support DWG, DXF, OBJ, VRML, STL and glTF formats. STL is de-facto standard in 3D printing.
Import and export 3D parts and assemblies in /5(). CAD Open Data Exchange (ODX) Libraries is a set of CAD-independent API for reading and writing native CAD files. File formats supported include Catia V4, Catia V5, CATIA V6, CATShape, Unigraphics, SOLIDWORKS, JT, PDF, Parasolid, IGES and STEP.
STEP encodes 3D geometry data in the Boundary Representation (B-Rep) form. Rep is a graph data structure with each of the nodes representing the faces/edges/vertices and the links between the nodes contains the adjacency relationships.
For instan. STEP-NC is a machine tool control language that extends the ISO STEP standards with the machining model in ISOadding geometric dimension and tolerance data for inspection, and the STEP PDM model for integration into the wider enterprise.
The combined result has been standardized as ISO (also known as AP). STEP-NC was designed to replace ISO /RSD G. The fact that geometry models from a CAD system are inexact may surprise some people.
But the explanation provided here by guest authors Benjamin Urick and Benjamin Marussig may be one of the most concise explanations of that fact I've seen.
They illustrate the reason I say geometry modeling is to mesh generation as turbulence. CAD and Model Requirements. The Geometry Tools are available for all Parasolid- and Acis-based geometry models as well as for Pro/Engineer geometry that has been launched using Granite. The Geometry Tools are not available for Pro/Engineer launched with the Mechanica method.
This is because the Geometry Tools change the underlying geometry. During the course of engineering analysis there are many information flows which would benefit from the availability of neutral file exchange.

CAD data exchange 1. Data Exchange Between CAD/CAM Systems 2. • Design projects require data to be shared between suppliers • Different companies often used different CAD systems • All CAD systems have their own database formats • They are mostly proprietary and often confidential • Data is stored in different ways e.g.or X,Y,Z, etc.
• Data conversion between. PDES (Product Data Exchange Standard) (then Product Data Exchange Using STEP) • to support any industrial application such as mechanical, electric, plant design, and architecture and engineering construction • to include all four types of data which is relevant to the entire life-cycle of a product: design,File Size: 6MB.
Therefore, exchanging data between different CAD programs requires neutral files that drop proprietary information and reproduce only the essential geometry. In this article, we looked at several formats such as STEP, IGES and Parasolid neutral files.
In my experience, the STEP format is the most robust with the highest fidelity transfer. CAD-geometry and solid modelling concepts (CSG, B-rep) as well as current CAx exchange formats (STEP, IGES, DXF, SET). Special attention is devoted to STEP; the ISO STandard for the Exchange of Product data (ISO) which addresses industry needs for data sharing between CAx applications and storage of product Size: 28KB.
This book uses the latest technology to address the basic theories involved in solving descriptive geometry problems. By incorporating the practical use of computer-aided drafting and design software into the theories and solutions, Descriptive Geometry: An Integrated Approach Using AutoCAD, 2E gives readers an edge that traditional descriptive geometry textbooks don't provide/5(4).ISO or STEP.
The STandard for the Exchange of Product model data (STEP) is the acronym for the full ISO standard. STEP consists of parts each having a distinct function within the formalization of exact data exchange within a predefined set of business activities (the scope).
