Convert ASM to another file type
To convert ASM Assemblies to another format, you need Solid Edge or other Cad software.
Convert a file to ASM
To convert other file formats to the "3D Assembly / Code" file type, you need software like Solid Edge or a similar tool.
About ASM files
The .ASM file extension serves two entirely distinct purposes. Primarily, it is a proprietary 3D CAD assembly file used by software like Siemens Solid Edge and Siemens NX. Alternatively, it functions as a plain text file storing low-level Assembly language source code for architectures like x86, MIPS, RISC-V, or the Intel 8051 microcontroller. The main challenge with CAD .ASM files is that they are structurally restricted. They do not store actual 3D geometry; they only store the coordinates, relationships, and constraints of external part files (such as PAR or PRT). If you send an .ASM file to a client without the referenced parts, it will load empty. Furthermore, these proprietary CAD files require expensive, specialized software licenses to open natively. For source code .ASM files, the limitation is readability. While any text editor can open them, non-programmers cannot easily interpret the machine-code mnemonics. To overcome these barriers, you must convert the file. For CAD assemblies, converting to universal formats like STEP or IGES is best for cross-platform editing in other 3D software. For archiving or client review, convert the assembly to a 3D PDF. For Assembly code files, convert to standard TXT or PDF to ensure formatting is locked and easily viewable by anyone. Drag and drop your file to analyze and convert it - free, online, and without installing software on convert.guru.
Convert.Guru analyzes your ASM file, detects the exact format, and lets you read the text inside.
If you want to convert ASM file to C, PDF, HEX, STEP, OBJ, BIN, TXT, EXE, STP, DWG, DXF or DGN, you can use Solid Edge or similar software from the "CAD Assembly or Source Code" category. In the File menu, look for Save As… or Export….
To convert SLDASM, DGN, PRT, IAM, X_B, CATPRODUCT, SLDPRT, RVT, DWG, CATPART, DXF or X_T files to ASM, try Solid Edge or another comparable tool in the "CAD Assembly or Source Code" category.
The ASM Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our ASM converter.
