Part and Assembly IGES Files
Assembly IGES Files
When exporting assembly files to IGES, the system generates an IGES file with the suffix _asm appended to the name of the file. This is to prevent overwriting a part file with an assembly file of the same name, as illustrated.

Part IGES Files
You can tailor part IGES files to the requirements of the receiving system. For example, you need not give surface information to a system that can only process curve geometry.
