EASYSKETCH requires a copy of Trimble SketchUp version 2013 upwards to be installed on your desktop computer. Choose either SketchUp 'Make' or the SketchUp 'Professional'. If you are a design professional we would recommend you use the 'Professional' version to take full advantage of all application features. The Professional version also comes with SketchUp Layout a superb standalone application for documenting your drawings.
Please note whilst EASYSKETCH will function under SketchUp v8 we recommend at minimum version as SketchUp 2013.
