Notes about the S12 file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to
scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The S12 file type is primarily associated with 'SPIRIT' by STI International, Inc.. SPIRIT offers a toolset available to architects, planners and designers across industries. It does this with a hybrid approach; including, an ability to produce documentation that is architectural in nature and not mechanical and use of smart parametric building objects (walls, windows, doors etc.).
