SCDOC is an extension given to files that are used by a software called SpaceClaim. It is a CAM type application by SpaceClaim Corporation for the design and modeling of 3D elements. It works under the control of Windows.

SCDOC is a format specially developed for SpaceClaim. The structure of SCDOC files is the same as that of ZIP archives. These files, in turn, store compressed data in XML format used in the project. This is information about individual elements of such a document, e.g. planes or edges.
