Technical note

How IGS and DCM differ in practice

A 3D model has no front of its own, so the DCM shows it from one viewpoint: the angles you set on the X, Y and Z axes, or a preset such as the isometric view. Whatever faces away from that viewpoint is not in the picture, so a part with features on several sides needs several images, which the multiple-frames option renders in one run. IGS describes geometry rather than pixels, so it has no inherent resolution. The conversion renders it at whatever size you choose, and that choice is final: enlarging the DCM afterwards will not recover the sharpness. Set the output dimensions or DPI before converting, not after.

FAQ

IGS to DCM Conversion

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.

What are DCM files?

A DCM file is a DICOM file, meaning it follows the Digital Imaging and Communications in Medicine (DICOM) standard for storing, transmitting, and managing medical imaging data. This standard ensures interoperability between medical imaging equipment and software, allowing images to be shared across scanners, servers, workstations, and network systems. DCM files are most commonly used in hospitals, clinics, and private medical practices that rely on medical imaging equipment such as CT, MRI, and ultrasound devices.
