BricsCAD Shape is a Free SketchUp Alternative for Ubuntu
Anyone looking for a free #SketchUp alternative for Linux desktops may want to check out BricsCAD Shape.
BricsCAD shape is designed for quickmockups, models and buildings rather than overly detailed or fastidious design word. It comes with a well-stocked library of materials, textures and ready-made 3D components that can be easily resized, grown, etc (it also supports creating shapes from scratch, too).
Creations can be exported in the .dwg file format used by leading industry software like DraftSight and AutoCAD, and free applications like FreeCAD, LibreCAD and the Teigha .dwg viewer.
