Which file format is commonly used for Inventor assemblies?

The file format commonly used for Inventor assemblies is the Inventor Assembly File format, which is denoted as .iam. This format is specifically designed to store the relationships and constraints between multiple parts and subassemblies that are included within a complete assembly model.

By using the .iam format, users can effectively manage and manipulate complex designs, control the assembly process, and analyze the interactions between components within the Inventor environment. The .iam files allow for features such as assembly constraints, which prevent parts from moving inappropriately relative to one another, making it essential for effective 3D modeling and engineering.

In contrast, the other formats listed have different purposes: .dwg is primarily used for 2D drawings, .ipt is for individual part files, and .dxf is a drawing interchange format used primarily for transferring drawings between different CAD software. Each of these formats serves important roles, but none are designed specifically to handle the assembly properties and functionalities that .iam files provide.
