Visual Tool Name & Description Visual Tool Name & Description
     Select ­ Use this tool to "select" the parts of your model you want to work with.
         3D Text ­ Use this tool to create 3 dimensional geometry from text.
      Paint Bucket ­ Use this tool to assign materials and colors to pieces of your model.
      Push/Pull ­ Use this tool to push and pull surfaces in your model, allowing you to add or subtract volume from the pieces in your model.
       Eraser ­ Use the Eraser tool to delete entities. The Eraser tool can also be used to hide and soften edges.
          Rotate ­ Use this tool to rotate, stretch, distort, or copy entities along a rounded path.
       Rectangle ­ Use this tool to draw rectangular pieces in your model.
          Follow Me ­ Use this tool to duplicate the profile of a face along a path.
       Circle ­ Use this tool to draw circles in your model.
          Scale ­ Use this tool to resize and stretch pieces in your model.
     Line ­ Use this tool to draw edges or lines in your model.
         Tape Measure ­ Use this tool to measure distances, create guide lines or points, or scale a model.
      Freehand ­ Use this tool to draw irregular hand­drawn lines in the form of curves.
      Offset ­ Use this tool to create copies of lines and faces at a uniform distance from the originals.
    Arc ­ Use this tool to draw arcs in your model.
       Move ­ Use this tool to move, stretch and copy pieces of your model. This tool can also be used to rotate components and groups.

       3. SketchUp
       3.1
SketchUp
3D computer program used in architecture, interior design, landscape architecture, civil and mechanical engineering, film and video game design.
       3.2
Advantages of SketchUp
1. It’s easy to draw your design because it’s designed to behave like an extension of your hand.
2. Simple-to-learn 3D drawing tool. 3. SketchUp is accurate and precise.
