What is an S12 file?

S12 files mostly belong to Fresco CAD. The S12 file is a CAD drawing file that uses the Microsoft Compound file format to store design data in a structured, binary container.
It is primarily used for creating and sharing engineering drawings.

This file type embeds complex vector graphics and metadata.

It is linked with Fresco software for CAD designs.

It is also known as the MicroStation Redline File in systems from Spirit.

FilExt.com note: Use a CAD program that supports the compound file structure to open and view these files.
