Draft Layer

Description
The Draft Layer creates a special kind of group that controls the visual properties of objects placed inside of it. By changing the properties of the Layer, such as line width, line color, shape color and transparency, the changes are propagated to the objects that make use of the Layer property.

This tool replaces Draft VisGroup starting from FreeCAD 0.19.

Note: The BIM Workbench offers a complete layer manager tool, which will eventually be included in Draft.

Usage

 * 1) Go to the menu . This adds a new layer. If it is a the first layer, a Layers object will be created too, which contains all the layers.
 * 2) To add objects you can drag them into the layer. This will remove the objects from there original layer. If you want to have an object in several layers, e.g. to control the visibility of different sets of objects, you have to edit the Group property of the layer. Click the button occurring to the right and select/deselect the objects you want to have in or out of the layer.
 * 3) Change the desired view properties of the Layer.
