There are lots of ways that you can refine this process to improve the look of the tree. You may find that the tree doesn't look quite right and that there autocd gaps in the canopy. This is good drawing practice.

The object behind this exercise is twofold. Once you are quite happy with your tree and you have saved it you can use it hree a block insert in any other drawing. Firstly it is to give you practice with some of the 3D techniques which you have discovered in the tutorials or to introduce you to them if you haven't seen them before.
The illustration on the right shows a tree with a conical shape.
At the end of this exercise you should have something which looks similar to the illustration on the right. However, running a site like CADTutor does cost money and you can help to improve the service and to guarantee its future by donating a small amount.
When you have completed the tree you will have a block which can be used in future drawings.

By changing the colour of the leaf layers you can hint at seasonal changes. Secondly it is to demonstrate a reasonably simple method for constructing a convincing 3D tree. The key is to experiment.
If this is the case just go through the process again and use a different leaf pattern or add more leaves. If you found this tutorial useful, you might like to consider making a donation.
For example you could draw leaves on three different layers and give each layer a slightly different colour to increase the tonal range. Once you have done that you can also remove the layer itself using the Layers command or the PURGE command, see the " Object Properties " tutorial for details.
It is quite difficult to construct convincing looking 3D trees in AutoCAD, however, with a few simple 3D commands at your disposal you should be able to create something which is identifiable as a tree and perhaps hint at a species. The insert base point of this block will be the base of the tree trunk because you drew the tree with the co-ordinate system origin 0,0 in that location. If you do decide to keep your tree for future use it is worth tidying the drawing up a little.

You could draw leaves on both halves of the canopy so that the tree doesn't look too symmetrical when viewed face-on. Follow the sequence below to complete the exercise.
