Note
The ANIPATH command has several severe limitations: it is not possible to asso-
ciate an existing camera to create the animation, it is not possible to control the
camera's parameters, such as lens length or field of view, and it is not possible
to control output quality, such as selecting an animation codec.
Connecting to other programs
Often we need to import or export our model to other programs, such as 3ds Max or
Revit. As we are dealing with different types of files, some care must be taken.
Typical 3D import and export formats
It is quite simple to connect to AutoCAD. Besides the AutoCAD DWG file type that
most CAD systems can export or import, the program accepts several 3D file types:
• SAT : These are the ACIS solid modeling files
• FBX : These are the 3D standard files that allow sharing 3D models
between Autodesk software, such as Revit
• DGN : These are the Microstation files
• IGES and IGS : These are the standard neutral files
• STL : These files are only for exporting stereo lithography files, which are
used for prototyping machines
Additionally, AutoCAD can import the following file types:
• 3DS : These are the old files of 3D Studio (MS-DOS versions)
• IPT and IAM : These are the Autodesk Inventor parts and also the as-
sembly files
• MODEL, SESSION, EXP, DLV3, CATPART, and CATPRODUCT : These
are the CATIA files
• IJ : These are the JT solid modeling files
• X_B, X_T : These are both Parasolid binary and Parasolid text files
• PRT, ASM, G, and NEW : These are the Pro/Engineer files
• 3DM : These are the Rhino files
