Dotgrid works by adding control points and drawing different line-types between them. The tool was created to design logos and glyphs for various Nataniev projects, and made available as a free and open source application.
Choose between 3 types of strokes, lines, arc and 3-points beziers. The application can be entirely operated with the keyboard and can render as both PNG and SVG files. Additional effects like horizontal, vertical and radial mirror are also available - as well as the stroke width and linecap can also be changed. The application menu can be hidden by pressing the tab key.
