Okino licenses the ProE/Creo software from PTC Corp. and embeds it directly into Okino software for use in importing complex native ProE/Creo datasets. This is one of the most demanded, used and refined of all Okino CAD conversion pipelines.
You would either want to import the top-level ProE/Creo .asm assembly file, or ask your client for "ProE/Creo Neutral files" and import the top-level .neu assembly file. Contrary to what some people initially try to do, please do not import every .prt file in a directory; rather, what you do with ProE/Creo datasets is only import the single, top-level assembly file. The name of that file must be provided to you from the client provider. NOTES-END STEP | .stp, .step, .ste | AP203 and AP214 NOTES-START STEP AP203 allows users to exchange geometry, topology and configuration data of a part or the whole product assembly. The user can exchange wireframe models, surface models and boundary representation of exact or faceted three-dimensional solids. STEP AP214 is a super set of AP-203 to define core data for automotive mechanical design processes.
STEP (which is short for STandard for the Exchange of Product model data and is also known as ISO 10303) is a standards-enabled technology for manufacturing developed by the International Organization for Standardization (ISO) to improve the exchange of data to meet a variety of industrial needs. This data includes design solids, product structure, product management and kinematics.
STEP AP203 and AP214 (which are supported in the Granite STEP importer) allow organizations to exchange 3-D solid, surface and wireframe geometry between heterogeneous CAD systems. These two APs can exchange a complete assembly of parts together with configuration management data and more, instead of just a single part.
STEP AP203 allows users to exchange geometry, topology and configuration data of a part or the whole product assembly. The user can exchange wireframe models, surface models and boundary representation of exact or faceted three-dimensional solids.
STEP AP214 is a super set of AP-203 to define core data for automotive mechanical design processes. NOTES-END PTC IGES (all variations) | .igs or .iges | Various NOTES-START IGES, or the Initial Graphics Exchange Specifications, is by far one of the most openly accepted and implemented neutral file formats used to transfer CAD data between dissimilar modeling programs and applications. The file format specification is over 300 pages and over 1" thick; however, most IGES files only use a subset of the full specification.
We consider there to be 3 main types of IGES files:
This importer handles all variations of IGES files in a very robust and time tested manner.
Parasolid | .xmt, .xmt_txt, .xmt_bin,
.xmt_neu, .x_t, .x_b, .x_n | Various NOTES-START The Parsolid .x_t importer is written by PTC and does not use the Siemens Parasolid modeling toolkit to import and handle the .x_t file.
Parasolid is a common, popular and well established 3D solids modeling toolkit. It forms the basis, or is used, with many 3D modelers, including Unigraphics/NX, SolidWorks and Solid Edge. The native file format is the Parasolid ".x_t" format.
Through decades of experience, we at Okino have found that the 'STEP AP214' file format is the most stable and mathematically sound method to source CAD data from UG NX. We would recommend using STEP over Parasolid format. STEP AP214 is also the preferred method to source files from Solid Edge, if and when you do not wish to import native Solid Edge files.
If you are importing from SolidWorks, and don't have native SolidWorks files available to you, then ask your client or vendor for 'IGES solids' files. NOTES-END Okino IGES (surfaced data) | .igs, .iges | 5.3 NOTES-START The Okino IGES import importer has been bundled together with the Granite/Pack license as a complement to the PTC IGES importer and other CAD importers. In general you will always want to import your files with the PTC IGES importer, although the Okino IGES importer is written for, and very fast to process, "Trimmed Surface" IGES file variations. NOTES-END SAT (ACIS) | .sat | Various NOTES-START The ACIS .sat importer is written by PTC and does not use the native Spatial ACIS toolkit to import and handle the .sat file. Please refer to the Okino/Spatial SAT/SAB importer which is the defacto method to import ACIS models for all past and current versions of the file format.
"SAT" is the native ASCII based file format of the industry standard "ACIS" 3D solids modeling toolkit developed by Spatial Corp. Programs which are based upon the ACIS 3D solids modeling toolkit will naturally import and export this file format.
It is extremely rare when a customer will use the SAT file format in this day and age. NOTES-END Granite "g-plugs" | .g | Various NOTES-START This is an expansion mechanism that allows 3D data to be imported from other vendors by way of their own dynamic "g-plug" plug-in modules. NOTES-END Pro/DESKTOP | .des | Current PTC version NOTES-START This is the native file format to import solids data from the PTC Pro/DESKTOP modeler. A free version of this solids modeler (Pro/DESKTOP Express) can be downloaded from the PTC WEB site. NOTES-END VDA-FS | .vda, .vdafs | v2 or older NOTES-START VDA-FS is similar in concept to IGES files, but of a much more limited nature. It conveys NURBS 3D surface geometry data only, and no information about colors, layers or text annotations. It was meant to move 3D surface data from one CAD system to another, with the fewest number of problems and with the least amount of work. You should consider using all of the other Granite converters first (or even VRML, XGL, etc) before using VDA to transfer CAD data.
VDA-FS is a German standard for transferring CAD geometric data amongst various CAD systems. It was developed by the German Automobile Manufacturers Association, the Verband der Automobilindustrie E.V (VDA, "http://www.vda.de"), as the German national standard, DIN 66301. NOTES-END
