DWG to FITS: what to expect from the conversion

DWG 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 FITS afterwards will not recover the sharpness. Set the output dimensions or DPI before converting, not after.

"If you work with AutoCAD, Autodesk, or similar CAD software, you’ve likely faced format compatibility issues. Every developer seems to insist on their own proprietary formats, making conversions a real challenge. The solution? reaConverter. This tool effortlessly handles two-way conversion between dozens of specialized formats!"

DWG to FITS Conversion: FAQ

What are DWG files?

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. DWG files contain complex design structures including several layers, which can be 2-dimensional or 3-dimensional.

What are FITS files?

The FITS (Flexible Image Transport System) format is a standard format used particularly for storing, transferring and processing scientific images from fields such as astronomy. FITS was first launched as an open standard in the early 1980s and has gone through several subsequent upgrades.
