How It Works

Technical note

How FIT and IGES differ in practice

FIT is made of pixels and IGES stores geometry, so the conversion traces the image into real lines, arcs and polylines. The result is editable in CAD: entities can be selected, snapped to and measured, rather than a bitmap wrapped inside a IGES container, which is what a viewer or a lightweight converter usually produces. It is still derived geometry, so expect contours rather than a structured drawing. Dimensions, blocks and meaningful layer names were never in the FIT to begin with. One FIT file can hold several pages or frames, while IGES holds one image each. reaConverter writes a separate output file per page and numbers them, so a single input can produce a whole folder of results.
