What is SketchUp ?
SketchUp is useful from the earliest stages of design to the end of construction. Programming, diagramming, design development, detailing, documentation, RFIs-wherever you need drawings, SketchUp pro comes in handy. Find a 3D model of anything necessary for your design work, turn models you have created into documents and customize your own add on tools to take away 3D modeling issues that may occur in other programs.
