Description

Std LinkMakeRelative.svg Std LinkMakeRelative creates an App Link (App::Link class), just like Std LinkMake.svg Std LinkMake, but it operates on selected subelements first, and sets the DataLink Transform to true.

Usage

With selection:

  1. Select a subelement in the 3D view, this means a vertex, edge, or face, or any combination of these. These subelements must belong to a single object.
  2. Press the Std LinkMakeRelative.svg Std LinkMakeRelative button. The produced object has the same icon as the original object, but has two arrow overlays indicating it is a relative Link.

Without selection:

  • If no object is selected, this command does nothing.
  • If an object is selected in the tree view only, but no subelement is selected in the 3D view, the command does nothing either.

Original body, and three Links created from the subelements of it, including edges and faces.


Properties

This command creates a new App Link; its properties are described in Std LinkMake.svg Std LinkMake.

In particular, DataLink Transform is set to true, so DataPlacement becomes hidden, and instead DataLink Placement controls the position of the Link with respect to the position of DataLinked Object.

Scripting

See Std LinkMake for the general information.

An App Link is created with the addObject() method of the document. To define a relative link, its setLink method is used to pick the source object, and one or more of its subelements. Then the LinkTransform attribute is set to True.

import FreeCAD as App

doc = App.newDocument()
body = App.ActiveDocument.addObject("Part::Box", "Box")

obj = App.ActiveDocument.addObject("App::Link", "Link")
obj.setLink(body, '', ['Edge1', 'Edge6', 'Edge7', 'Edge10', 'Face2', 'Face3'])
obj.LinkTransform = True
obj.LinkPlacement.Base = App.Vector(20, 20, 0)
App.ActiveDocument.recompute()
