Make a Chair on SketchUp

A chair is a good project for beginners because it teaches many of the basic strategies used in SketchUp.

Steps

Open Google SketchUp. Google SketchUp 6 can be downloaded for free at the SketchUp website. This is not hard to do.
Create a rectangle and use the PUSH/PULL tool to create a 3D rectangle.
Using the Line tool, draw a side-view 2D chair on one sides of the object.
Use the Push/Pull tool to remove the blocks and shape the chair.
Change your view to under the chair and create a rectangle for the front leg.
Use the Push/Pull tool to push that part away and shape the front legs of the chair.
Repeat steps 5 and 6 for the back legs of the chair.
Increase the height of the backrest of the chair and create an arc near the top using the Arc tool.
Use the Push/Pull tool to shape the final form of the chair.

You could also make a square in the centre of the chair seat which is almost as big as the seat itself. Pull it up slightly to make a seat cushion
The strategy of making shapes and pushing/pulling them out can be used to make many things.
You can make this chair in a smaller size as well.
