E-Links - Supported Model Formats

The following model formats are supported by the E-links feature in the Autodesk Fabrication products.

File Name	Description
*.CAJ	*.CAJ (Archived Job File - Autodesk Fabrication Products) Similar to *.ESJ, this is also a format for saving jobs but includes much more information about the job, as it includes the Autodesk Fabrication products database, and therefore will also save all the settings that can be found in File Setup Main Database. This is often required if you need to send the job file to a technical support representative, or transfer the job from one location to another, as the settings at different sites may be different.
*.MAJ	*.MAJ (Global Job File - Autodesk Fabrication Products) *.MAJ File is a Manufacturing Job File that is created in an Autodesk Fabrication product (CADmep, ESTmep, or CAMduct). This file contains the all fittings in the job, along with connector and seam information. If a MAJ is opened in a copy of the s that it was not created in, it will try to match connectors, seam, and Sspecification information, if it cannot match, or is redeveloped in the other software, it will use the specification rules relevant to that copy of the software.
*.ESJ	*.ESJ (Archived Job File - Autodesk Fabrication Products Similar to *.MAJ,. This is also a format for saving jobs but includes much more information about the job, as it includes the database, and therefore will also save all the settings that can be found in File Setup Main Database. This is often required if you need to send your job file to technical support representative, or transfer the job from one location to another, as the settings at different sites may be different than yours.

Introduction to (Industry Foundation Class - IFC)

Introduction to (Industry Foundation Class - IFC) - The Industry Foundation Classes (IFC) data model is a neutral and open specification that is not controlled by a single vendor or group of vendors. It is an object-oriented file format with a data model developed by the International Alliance for Interoperability (IAI) to facilitate interoperability in the building industry, and is a commonly used format for Building Information Modeling (BIM). The IFC model specification is open and available. Because of its focus on ease of interoperability between software platforms, the Danish government has made the use of IFC format(s) compulsory for publicly aided building projects.

Autodesk Fabrication Products Supporting IFC Model Formats

File Name	Description	Read	Write
*.Bix	*.Bix (Industry Foundation Class - IFC): This is a binary IFC Xml format, therefore the advantages are that this file fomat is fast and small both for reading and writing model data.	Yes	Yes
*.ifcZIP	*.ifcZip (Industry Foundation Class - IFC): This is a compressed format of the IFC model types. This is a lot smaller, faster writing, but as slow as *.IFCXML for reading. The reason for this is because it is decompressed to one buffer in memory first.	Yes	Yes
*.ifcXML	*.ifcXML (Industry Foundation Class - IFC): This is a format of the IFC model types. The actual file sizes are huge compared to the various types available, but one of the advantages is that the data is more structured, or "token-ized".	Yes	Yes
