Gcmc is a front-end language for generating G-code, SVG, and DXF for CNC mills, lathes, laser cutters, and other numerically controlled machines employing G-code, SVG, or DXF. The language is a context-free grammar created to overcome the archaic format of G-code programming, but can be used more generally for many targets. Gcmc aims to be more readable and understandable than G-code and enable programmatic designing. Gcmc makes extensive use of vector mathematics to support the 3D nature of CNC machining. It handles units as millimeters, mils (inch), degrees, and radians and performs automatic conversions where necessary.
F-Engrave generates g-code tool paths for CNC machines using CXF fonts, true type fonts (TTF), or a 2D DXF file. It can generate tool paths for engraving or v-carving text or a DXF design. The output of F-Engrave can be imported into EMC2, MACH3, or other machine controllers. F-Engrave output can be reopened by F-Engrave for later editing. F-Engrave designs can also be exported as SVG files.
DXF2papercraft converts a polygonal 3D model stored as a DXF file into a plain drawing in the form of a 2D DXF file. This requires the program to "unfold" the 3D model. The result is a flattened pattern of connected polygons. All edges of a polygon which are unconnected get a so-called glue tab in addition. This pattern is called a papercraft model, and it can be used to build a shape that resembles the original 3D model from paper or cardboard. After all pairs of tabs have been glued together, the paper model corresponds to the 3D object. The final model can be reinforced by fiber glass and resin to obtain a rigid, resilient structure.
DXF Export Java is a Java library for exporting CAD entities, along with their properties, to stream or AutoCAD DXF files at high speed and with ease. Creating a new DXF file takes only one call of the exporter class, provided that user data has been prepared and loaded to the required fields beforehand. The library handles all major entities, including Arc, Bezier, Circle, Ellipse, Hatch Pattern, Line, Multi-line Text, Pixel, Polyline, Rectangle, and Text. It also supports layers, colors, line styles, and other important properties. Source code and working demos are included.
