What is an IDCL file? An IDCL file is a library file used by Autodesk Inventor, an application utilized to design three-dimensional prototypes. It stores tables of numerical data that represent parts, such as screws, nuts, pins, and bolts that can be inserted into Inventor assemblies ( .IAM files) as parts ( .IPT files) by Inventor users.

More Information IDCL files may store various types of parts, such as steel shapes, shaft parts, and fasteners. Different types of standard content include ANSI, DIN, GOST, ISO, JIS, and GB. You can view the location of IDCL libraries for a project in Inventor by selecting "Projects" in the "Get Started" ribbon, click the "Configure Content Center Libraries" and click the "Location of Libraries" hyperlink to go to the location of the IDCL files. Typically, IDCL files are located in the following directory: C:\​ProgramData\​Autodesk\​Inventor [version]\​Content Center\​Libraries NOTE: You can install IDCL libraries in Inventor from the Installer landing page by clicking "Autodesk Inventor Content Libraries," then selecting the IDCL files.
