FAQ
CT1 to IGS Conversion
What are CT1 files?
CT1 is a raster image file extension used for CALS Type 1 files, defined by the U.S. Department of Defense Computer-aided Acquisition and Logistic Support (CALS) initiative in the MIL-R-28002 specification, and later incorporated into MIL-STD-1840 for the exchange of technical documentation. A file of this type contains a single black-and-white page, stored as a bilevel image compressed with the CCITT Group 4 (ITU-T T.6) method, which made it well suited to scanned engineering drawings, manuals, and archival paper documents. The page is preceded by a fixed-length text header that identifies the source document, the figure, the document class, the pixel dimensions, the page orientation, and the scanning density. The format supports no color or grayscale, and remains in use in legacy technical document archives.
What are IGS files?
The IGS (Initial Graphics Exchange Specification) file format is a standardized CAD data exchange format used to transfer 2D and 3D model data between different CAD systems. Developed in the 1980s, IGES ensures compatibility across various engineering and design software by storing geometric data, annotations, and structure in a neutral ASCII or binary format.
