ISH to DWG Conversion: FAQ

What are ISH files?

ISH is an archaic bitmap image format associated with Image Speeder and Image System — two image processing programs which have been long discontinued. In case you found such a file on your hard-drive or were sent one, it is probably very old and will be difficult to open. For best results, we recommend converting it to a more widely used format.

DWG (which stands for "Drawing") is a proprietary format of AutoCAD, a program widely used for creating engineering and architectural projects. The format is also a default extension used by several other computer-aided design (CAD) pieces of software, including IntelliCAD, Caddie or DraftSight.
