Rules for designing with layers

♦ The layers capability is turned OFF by default. To use layers, you must turn on the
Layer Manager in View > Layer Manager. You can change the default setting on the
Tools > Options > View tab.
Note: If you open a plot file with layers and Layer Manager is turned off, the layers still exist
even though you can not see them. If you encounter difficulty viewing or selecting objects
turn on Layer Manager using the View menu.
♦ Each new Composer job opens with one layer known as the Layer 1.
♦ Jobs designed in previous versions of OMEGA open onto a single layer which has the
same name as the plot file.
♦ Click the New Layer button on the Layer Manager or select New Layer in the Layer
Menu to add a layer to the job.
♦ The top layer is the foremost layer in the job and is in front of all other layers.
♦ To design on a particular layer, select the layer to make it active.
♦ It is helpful to position a design at the 0,0 point on the Composer work surface so that
it is also positioned at that location in GSPPlot. To move to the 0,0 location, Select All
and click Shape > Absolute Move. Enter a 0 in the New Location X, Y box and click OK
to move the lower left corner of the selected objects to 0,0 on the rulers.
♦ Rearrange layers by dragging the layer above (in front) or below (in back) other layers
in the Layer Tree.
♦ Hide or display layers by clicking the eye icon or choosing the Show or Hide
commands in the right-click menu. Hidden layers can still be output. Show or Hide all
layers using the Show All Layers or Hide All Layers commands in the Layer Menu.
♦ Lock or unlock layers by clicking the lock icon or by choosing the Lock or Unlock
commands in the right-click menu. When layers are locked, you cannot select or edit
