Troubleshoot (Autodesk Alias)

If the files you import contain unsatisfactory data, change the following import options in Autodesk Alias: Default Trim Curves Specifies the trim curves that the processor uses. You can select parameter space curves, model space curves, or use the flag that is present in the IGES file. By default, the preference flag in the IGES files is used.

Shrink Surface When turned ON, Alias detects trimmed surfaces with trim boundaries that are the same as, or isoparametric to, the natural boundaries of the untrimmed surface. It then converts these surfaces into Alias surfaces by shrinking the untrimmed surface to the trim boundaries. When turned OFF, Alias converts all trimmed surfaces of this type to Alias trimmed surfaces.

Types of data imported

The DirectConnect for IGES translator imports ASCII format IGES files with or without linefeed characters at the end of each record. The software does not support Binary IGES files.

Granite ➤ A CAD technology platform for design collaboration using solid models.

IAM (.iam) A file format in the Autodesk Inventor software represent an assembly.

IGES (Initial Graphics Exchange Specification) A file format for transferring graphics data between CAD/CAM systems. A neutral file format that can be imported into any number of CAD or modeling packages.

50 | Glossary IPT (.ipt) A file format in the Autodesk Inventor software to represent a part.

IV (.iv) A file format in the Open Inventor software.

JT JT is a DirectModel file format that is developed and supported by the JT Open Program for the visualization of 3D models.

NX ➤ NX is a solid modeling package based on the Parasolid kernel. The package contains many (mostly optional) modules: for example, CAD, CAM, CAE, sheet metal applications, knowledge bases, quality control, and rapid prototyping. The files structure is binary.

Open Inventor™ Open Inventor is a legacy 3D file format from Silicon Graphics, Inc. Open Inventor is not related to Autodesk Inventor software. Open Inventor is an object-oriented 3D toolkit that describes complete 3D scenes, which can be made interactive and that are optimized for OpenGL. It is an ASCII or binary file format.

PCRE The Perl-compatible regular expressions is a library of functions to support regular expressions, with syntax and semantics as close as possible to the syntax and semantics in the Perl 5 language.

STEP (.step) An international standard for the exchange of geometric product definitions. STEP formats that are relevant to Autodesk products are AP203 (general mechanical CAD) and AP214 (automotive CAD).

STL An STL (StereoLithography) file is a triangular representation of 3D surface geometry. The surface is tessellated, or broken down logically into a series of small triangles (facets). A perpendicular direction and three points representing the vertices (corners) of the triangle describe each facet.

STP (.stp) A file format used in STEP (Standard for the Exchange of Product Data) for transferring graphics data between CAD/CAM systems.

V3Rx A file format generated by a version of CATIA that is older than V4.

ZPR ZPrint CAD format (ZPR) is a proprietary file format developed by Z Corporation. It is used with ZPrint and ZEdit for printing on high definition color 3D printers. Autodesk Direct lets you export files in ZPR (*.zpr) format to use in the Autodesk Rapid Prototyping solution.
