Converting STEP format
I downloaded from the site GrabCad model in STEP format. I opened the file in SolidWorks. In the parts the properties of the material is missing. Tell me if there is an opportunity to learn the parameters of the material, or STEP format does not have such data?
I apologize for my bad english...
Thank you in advance for your help!
Coverage of STEP Application Protocols (AP)
The STEP APs can be roughly grouped into the three main areas design, manufacturing and life cycle support.
AP 201, Explicit draughting. Simple 2D drawing geometry related to a product. No association, no assembly hierarchy.
AP 202, Associative draughting. 2D/3D drawing with association, but no product structure.
AP 203, Configuration controlled 3D designs of mechanical parts and assemblies.
AP 204, Mechanical design using boundary representation
AP 207, Sheet metal die planning and design
AP 209, Composite and metallic structural analysis and related design
AP 214, Core data for automotive mechanical design processes
AP 235, Materials information for the design and verification of products
AP 236, Furniture product data and project data
AP 242, Managed model based 3d engineering (under development)
Connectivity oriented electric, electronic and piping/ventilation:
AP 210, Electronic assembly, interconnect and packaging design. The most complex and sophisticated STEP AP.
AP 212, Electrotechnical design and installation.
AP 227, Plant spatial configuration
AP 215, Ship arrangement
AP 216, Ship moulded forms
AP 218, Ship structures
AP 225, Building elements using explicit shape representation
AP 232, Technical data packaging core information and exchange
AP 233, Systems engineering data representation
AP 237, Fluid dynamics
AP 219, Dimensional inspection information exchange
AP 223, Exchange of design and manufacturing product information for cast parts
AP 224, Mechanical product definition for process plans using machining features
AP 238 - Application interpreted model for computer numeric controllers
AP 240, Process plans for machined products
Life cycle support APs:
AP 239, Product life cycle support
AP 221, Functional data and schematic representation of process plants
AP 241, Generic Model for Life Cycle Support of AEC Facilities (planned)
The AP 221 model is very similar to the ISO 15926-2 model, whereas AP 221 follows the STEP architecture and ISO 15926-2 has a different architecture. They both use ISO-15926-4 as their common reference data library or dictionary of standard instances. A further development of both standards resulted in Gellish English as general product modeling language that is application domain independent and that is proposed as a work item (NWI) for a new standard.
The original intent of STEP was to publish one integrated data-model for all live cycle aspects. But due to the complexity, different groups of developers and different speed in the development processes, the splitting into several APs was needed. But this splitting made it difficult to ensure that APs are interoperable in overlapping areas. Main areas of harmonization are:
AP 214, 203 and 242 in the area of 3D mechanical design. AP 214 took over all of the functionality of the earlier AP 203 edition and then extending the capabilities significantly. The second edition of AP 203 (to be published in 2010/2011)[dated info] took over bigger parts of AP 214 by adding again new functionality. The upcoming AP242 will formally replace AP 203, 214 and other mechanical design APs
AP 201, 202, 212, 214, 221 and now AP 203 ed 2 for technical drawings with extension in AP 212 and 221 for schematic functionality
AP 214, 224 and 238 for machining features.
AP 203ed2, 210, 214, 224, 238 for Geometric dimensioning and tolerancing
For complex areas it is clear that more than one APs are needed to cover all major aspects:
AP 212 and 214 for electro-mechanical products such as a car or a transformer
AP 203/214, 209 and 210 for electro/electronic-mechanical products
AP 212, 215, 216, 218, 227 for ships
AP 203/214, 224, 240 and 238 for the complete design and manufacturing process of piece parts.
The whole scope of AP214 covers : (SOLIDWOIRKS HAS IT)
Products as mechanical parts , assemblies, tools used by manufacturing (in principle applied to description of cars),
Information for process plan, configuration control, applied to design phase
Data related to the documentation of design change process, approval, security classification,
Geometrical data as : wireframe, surfacic models, faceted models, manifold surfaces and solids (BREP), constructive solid geometry, hybrid models
References to product data represented in an other format than STEP
Tolerance data, Surface conditions.
In regard of this scope, limitations apply. These domains are in practice not covered :
Parametric representation of shapes,
Continous kinematics simulations over time,
Data related to finite element analysis (see AP209),
Data related to particular technologies such as pneumatic, hydraulic, electric, or electronic.
A second edition of AP214 has been issued in 2003, it introduces various corrections, but no change in the scope.
A third edition of AP214 is in preparation, to be harmonized with Object Management Group specifications on PLM services - as well as coming update of AP203 (E2).
SO STEP 214 CAN MANAGE THAT DATA , but depends on the cad application that the material information is passed to the file or not. You can see the capacity to manage material using the STEP format in the following link:
Here is possible to understand the code of STEP and how it works in the file.
A library of examples of the STEP code:
Thank jmiliani, for your detailed response!
From your answer, I learned a lot about the format of STEP.
I downloaded the files by clicking the link http://www.cax-if.org/library/index.html.
Once I discovered them in Solid Works. But just have not found any information about the material (he is listed as "not selected").
Maybe there exists some special tool that allows you to get all information about an existing file STEP? Or need to configure the correct settings for import into SolidWorks?
By the way, here's a model from which I would like to receive information on all materials:
Maybe someone can convert this file to SolidWorks with preservation of all available parameters and characteristics of the model?
Forgive me for stupid questions.
I have checked the file to import to Solidworks, this does not have information about material, you can open the file using "notepad" in accessories and search the word "material". In this case, the file doesn't have data about materials so Solidworks or any CAD software will never open it with this information.
I will check if I modify the file adding material information , Solidworks can used this information on its model.
I will tell you later!!!. By the way , try to ask Aratrum to attach its original format and We can get all the information .
Thank you jmiliani!
I wrote the owner of the file Aratrum,his name on site is Maas, but he did not answer me. Unfortunately, I can not find his e-mail. This is the policy of the site. Details of the materials would be very important to me ... Thank you very much for your help!
