An .ad_asm file is an Alibre Design assembly file used to create and work with assemblies in the CAD application. It stores the assembly structure and the placement of its components.
An assembly can include references to component part and subassembly files created in Alibre Design. Those referenced files may be required to display the complete design correctly.
The format is a native Alibre Design format rather than a general-purpose CAD exchange format. It is used by Alibre Design Professional on Microsoft Windows and is intended to be opened and edited in Alibre Design.
Open the file on Microsoft Windows with Alibre Design Professional. Use the program's Open command or open the file from Windows if Alibre Design is associated with the .ad_asm file extension.
Keep any part or subassembly files referenced by the assembly in their expected locations so that Alibre Design can load the complete design.
An .ad_asm file is not normally converted by renaming its extension. Open it in Alibre Design and use the program's available export or Save As options to create a supported CAD exchange file.
Conversion may export the assembly geometry without preserving all native Alibre Design features, relationships, or references. The available results depend on the target format and the export functions provided by the installed version of Alibre Design.
