"I needed to convert DWG to DXF for a laser cutter, and reaConverter did it flawlessly. The geometry remained intact, and the line weights were preserved. I've tried free tools, but they always mess up arcs. This is the only one I trust."

DWG to STL 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 STL files?

STL is the proprietary format for a computer-aided design (CAD) program developed by 3D Systems. STL is an acronym for Stereolitography, which is a type of technology used for creating prototypes or patterns through 3D printing. An STL file contains a surface representation of such a model, without detailed specifications of aspects such as colours. STL files can only be opened with a limited number of programs.
