In Draw three layers are always present by default: Layout, Controls, and Dimension
Lines. Layout is the default layer when you create a new drawing.
To change to a layer, click on its tab. Everything that is drawn will be placed on the
currently selected layer. The Controls layer is for control elements such as icons and
pull-down menus and is not usually used for ordinary drawing elements. The
Dimension Lines layer is used whenever you insert a dimension line on a drawing
(unless the layer is made invisible). Use Insert > Layer to insert a new layer into a
drawing (Figure 183).
On the Insert Layer dialog you can specify the following properties:
• Visible: If this property is not activated, the layer will not be shown (the layer
is removed from the stack).
• Printable: If this property is not activated, the layer will not be printed. This is
useful if you use a ‘draft’ layer for guides or annotations that you use in
making the drawing but should not appear in the final output.
• Locked: All objects on this layer are protected from deletion, editing, or
moving. No additional objects can be added to a protected layer. This property
is useful when a base plan is to be protected while adding a new layer with
other details.
Right-click on a layer tab to bring up a menu where you can insert or delete a layer,
rename an existing layer, or modify a layer. You can change the names of the user-
defined layers; the default layer names cannot be changed.
If you choose Modify the dialog is similar to Figure 183, but you cannot edit the
Name. You can edit the Title and Description and change the properties of the layer
(Visible, Printable, Locked).
