Working with Objects 137
• Click/unclick the Locked column to allow/prevent objects on the
layer from being moved, deleted, or resized. (Clicking
on the
Layer's entry locks the layer, which will then shown as
).
• To set a Selection colour, double-click the layer's name. From the
dialog, click the colour swatch (e.g.,
) and choose a colour from the
dialog. Assigning different colours to layers means that you can
quickly verify that a pasted object has gone to the correct layer, i.e. the
box surrounding the object on a layer always adopts the Selection
colour assigned to the layer. The layer shows its current selection
colour as a thin colour strip under the layer property icons.
Managing objects on layers
A useful feature of the Layers tab is that you can see objects or even groups of
objects, under the layer on which they were created. This gives you the option of
selecting an object or group from the tab as opposed to from the page itself.
Either group or object can be named, and once named, located on your page.
To add objects to a particular layer:
• When drawn, objects are added to the selected layer automatically.
This is why it is a good idea to check which layer you are currently
working on!
To select objects on a particular layer:
• In the Layers tab, if the Edit All Layers button is disabled, click
the chosen layer and either:
• Click the layer's object on the page.
- or -
• In the Layers tab, click the
Expand icon on the chosen layer
entry to reveal all associated objects. You'll see objects named
automatically, e.g. "Curve, 2 Nodes", "Closed Curve, 5 Nodes",
"Quick Rectangle", etc., each with their own preview. The front-
most object in your drawing always appears at the top of the
layer's listed objects (the order reflects the Z-order).
