WORKING BY LAYERS

Various auxiliary lines will be needed in order to draw the part. Since these auxiliary lines must not appear in the final drawing, they will be in a layer apart from the one used for the finished model.

Creating two new layers

1. Open the layer management
   window, which is found in the Utilities Layers menu.

2. Create two new layers called "aux" and "ok". Enter the name for each layer in the Layers window (Figure 1) and click New.

3. Choose "aux" as the activated layer. To do this, click on "aux" to highlight it and then click on the Layer To Use button. (The name of the activated layer will appear next to the button, "aux" in this case.) From now on, all the entites created will belong to this layer.
