Legacy 2D CAD. Full featured, including "snap to" drawing tools, user programmable active symbols, automatic dimensioning, sheets, layers, double lines. Includes templates for AEC, Electrical, Site, Org Chart, Welding. Includes tutorials.
Very good user interface designed for quick ease of use. Features are more than adequate for part time or hobbyist use and fast "prototyping" - hence "Sketch". GUI control is menu and mouse (or pad) driven, not text driven like all professional CAD programs; some text commands are available and more can be added as well as subroutines and macros with VB but that is not the primary purpose of this application.
Includes raster graphics import and import for other standard drawing formats; however the importer does not work correctly with all formats.
Exports to html and graphical formats.
