.ASM File Extension

Assembly source code file created by Microsoft Visual Studio, a Windows software development program; contains low-level source code that can be translated directly into machine code; typically used only for optimizing small segments of application code.

Since assembly code is typically more difficult to write than C or C++ code, ASM files are often combined with C or C++ files that handle the majority of the application logic.

Assembly file created by Pro/ENGINEER, a program used for designing three-dimensional products; contains one or more design parts (.PRT files) and their assembly specifications; used to combine parts together into an assembled component.

An ASM file may also be an assembly file created by Siemens Solid Edge, a CAD application used to create and manage assembly designs. It contains information about how different parts fit together in an assembly, which may include multiple components. Solid Edge uses these files to simulate and document product assembly.

Engineers and designers may use ASM files to prototype and simulate assembly lines and product configurations. They are an integral part of the product development cycle, providing insights into potential issues that may arise during the manufacturing stage.

ASM files are generated within Solid Edge when users assemble multiple parts to visualize the complete design. The files typically reside in directories where design projects are stored, often alongside Part files (.PAR) and draft files (.DFT).

You can open ASM files with Siemens Solid Edge in Windows. To open an ASM file with Solid Edge, select File → Open.
