Описание

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.

Применение

  1. Select the Utilities → New Layer option from the menu, or from the Tree View or 3D View context menu.
  2. If it does not exist the layer container is created first.
  3. A layer is created and put in the layer container.
  4. Optionally change the properties of the layer.
  5. 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 ДанныеGroup property of the layer.
  6. Optionally activate the layer.

Context menu

Layer container options

For a Draft LayerContainer these additional options are available in the Tree View context menu:

  • Add New Layer: adds a new layer to the current document.
  • Reassign Properties of All Layers: removes overrides from objects in all layers by reassigning the properties of the layer they are in. introduced in 1.1
  • Merge Layer Duplicates: merges all layers with the same base label.
The base label of a layer is its ДанныеLabel stripped of trailing digits and spaces. All layers with the same base label are merged into a single layer with the ДанныеLabel set to that base label.

Layer options

For a Draft Layer these additional options are available in the Tree View context menu:

Drag and drop behavior

introduced in 0.21

If you drop an object from a Std Group, or a group-like object such as an Arch BuildingPart, on a layer in the Tree View, it is not removed from the group, and vice versa. To remove an object from a layer it must be dropped on another layer or on the document node. There is no need to hold down the Ctrl key when dragging from or dropping on a layer.

Overrides

introduced in 1.1

Objects inside a layer can have overrides. The following logic applies:

  • When an object is put in a layer it always adopts the properties of that layer.
  • A property of the object that is subsequently changed is considered an override.
  • When a property of the layer, or the object in the layer, is then changed so that they match again, there is no longer an override, and the property is synced again.

The layer container and all layers have a context menu option to reassign properties and thereby remove overrides.

Примечания

Свойства

See also: Property View.

A Draft Layer object is derived from an App FeaturePython object and inherits all its properties. It also has the following additional properties:

Данные

Layer

  • ДанныеGroup (LinkList): specifies the objects that are inside the layer.

Вид

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, ВидLine Color and ВидShape Color, this behavior is optional.

  • ВидDraw Style (Enumeration): specifies the draw style of the layer: Solid, Dashed, Dotted or Dashdot
  • ВидLine Color (Color): specifies the line color of the layer.
  • ВидLine Width (Float): specifies the line width of the layer.
  • ВидOverride Line Color Children (Bool): specifies if changes to the ВидLine Color of the layer are propagated to the objects inside the layer.
  • ВидOverride Shape Appearance Children (Bool): specifies if changes to the ВидShape Appearance of the layer are propagated to the objects inside the layer. introduced in 1.0
  • ВидShape Appearance (MaterialList): specifies the shape appearance of the layer. introduced in 1.0
  • Вид (hidden)Shape Color (Color): specifies the shape color of the layer. It is kept synchronized with the Diffuse Color of the ВидShape Appearance.
  • ВидTransparency (Percent): specifies the transparency of the layer. It is kept synchronized with the Transparency of the ВидShape Appearance.

Print

  • ВидLine Print Color (Color): specifies the line print color of the layer.
  • ВидUse Print Color (Bool): specifies if the ВидLine Print Color of the layer is used when a TechDraw DraftView is created from the objects inside the layer.

Программирование

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(line_color=(1.0, 0.0, 0.0, 0.0),
                         shape_color=(1.0, 1.0, 0.0, 0.0))

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()
