Description
The Draft Layer command creates a Draft Layer. A layer is a special kind of group with a number of visual properties. These properties, and any changes to them, are propagated to the objects placed inside the layer. The layers themselves are put in another special group: the Draft LayerContainer.
This command has replaced the Draft VisGroup command in FreeCAD version 0.19.
Usage
- There are several ways to invoke the command:
- Press the Draft Layer button.
- Select the Utilities → Layer option from the menu.
- If the layer container already exists: right-click it in the Tree view and select the Add new layer option from context menu.
- If it does not yet exist the layer container is created first.
- A layer is created and added to the layer container.
- Optionally change the properties of the layer.
- Optionally put objects in the layer by drag and dropping them on the layer in the Tree view. Objects can also be put in a layer by editing the DataGroup property of the layer.
- Optionally activate the layer.
Layer container options
For a Draft LayerContainer these additional options are available in the Tree view context menu:
- Merge layer duplicates: this option currently does not work.
- Add new layer: adds a new layer to the current document.
Layer options
For a Draft Layer these additional options are available in the Tree view context menu:
- Activate this layer: makes the selected layer the active layer.
- Select layer contents: selects the objects inside the selected layer.
Notes
- A new layer can also be created with the Draft AutoGroup command.
- The BIM Workbench offers a complete layer manager tool which will eventually be included in the Draft Workbench.
Properties
See also: Property editor.
A Draft Layer object is derived from an App FeaturePython object and inherits all its properties. It also has the following additional properties:
Data
Layer
- DataGroup (
LinkList
): specifies the objects that are inside the layer.
View
Layer
The properties in this section are applied to objects that are put inside the layer. And any changes to these properties are propagated to them. For two properties, ViewLine Color and ViewShape Color, this behavior is optional.
- ViewDraw Style (
Enumeration
): specifies the draw style of the layer:Solid
,Dashed
,Dotted
orDashdot
- ViewLine Color (
Color
): specifies the line color of the layer. - ViewLine Width (
Float
): specifies the line width of the layer. - ViewOverride Line Color Children (
Bool
): specifies if changes to the ViewLine Color of the layer are propagated to the objects inside the layer. - ViewOverride Shape Color Children (
Bool
): specifies if changes to the ViewShape Color of the layer are propagated to the objects inside the layer. - ViewShape Color (
Color
): specifies the shape color of the layer. - ViewTransparency (
Percent
): specifies the transparency of the layer.
- ViewLine Print Color (
Color
): specifies the line print color of the layer. - ViewUse Print Color (
Bool
): specifies if the ViewLine Print Color of the layer is used when the objects inside the layer are placed on a TechDraw page.
Scripting

To create a Draft Layer use the make_layer
method of the Draft module. To add objects to, or remove objects from, a layer change its Group
property.
import FreeCAD as App
import Draft
doc = App.newDocument()
layer = Draft.make_layer()
lay_vobj = layer.ViewObject
lay_vobj.LineColor = (1.0, 0.0, 0.0, 0.0) # red
lay_vobj.ShapeColor = (1.0, 1.0, 0.0, 0.0) # yellow
polygon1 = Draft.make_polygon(5, radius=1000)
polygon2 = Draft.make_polygon(3, radius=500)
polygon3 = Draft.make_polygon(6, radius=220)
layer.Group = [polygon1, polygon2, polygon3]
doc.recompute()
