Draft

Description

The Draft Mirror command creates mirrored copies, Part Mirror objects, from selected objects. A Part Mirror object is parametric, it will update if its source object changes.

The command can be used on 2D objects created with the Draft Workbench or Sketcher Workbench, but also on many 3D objects such as those created with the Part Workbench, PartDesign Workbench or BIM Workbench.

Mirroring an object

Usage

See also: Draft Snap and Draft Constrain.

1. Optionally select one or more objects.
2. There are several ways to invoke the command:
   • Press the Mirror button.
   • Draft: Select the Modification → Mirror option from the menu.
   • BIM: Select the Modify → Mirror option from the menu.
   • Use the keyboard shortcut: M then I.
3. If you have not yet selected an object: select an object in the 3D view.
4. The Mirror task panel opens. See Options for more information.
5. Pick the first point of the mirror plane in the 3D view, or type coordinates and press the Enter point button.
6. Pick the second point of the mirror plane in the 3D view, or type coordinates and press the Enter point button.
7. The mirror plane is defined by the selected points and the normal of the Draft working plane.

Options

The single character keyboard shortcuts available in the task panel can be changed. See Draft Preferences. The shortcuts mentioned here are the default shortcuts.

• To manually enter coordinates enter the X, Y and Z component, and press Enter after each. Or you can press the Enter point button when you have the desired values. It is advisable to move the pointer out of the 3D view before entering coordinates.
• Press R or click the Relative checkbox to toggle relative mode. If relative mode is on, the coordinates of the second point are relative to the first point, else they are relative to the coordinate system origin.
• Press G or click the Global checkbox to toggle global mode. If global mode is on, coordinates are relative to the global coordinate system, else they are relative to the working plane coordinate system.
• Press S to switch Draft snapping on or off.
• Press Esc or the Close button to abort the command.

Notes

• Mirrored copies of Draft Lines, Draft Wires, Draft Arcs and Draft Circles can be turned into independent editable Draft objects by using Draft Downgrade and then Draft Upgrade.
• The Part SimpleCopy command can be used to create a copy of a mirrored object that is not linked to its source object.

Properties

See also: Property editor.

A Part Mirror object is derived from a Part Feature object and inherits all its properties. It also has the following additional properties:

Data

Base

• VeriSource (Link): specifies the object that is mirrored.

Plane

• VeriBase (Vector): specifies the base point of the mirror plane.
• VeriNormal (Vector): specifies the normal direction of the mirror plane.

Scripting

See also: Autogenerated API documentation and FreeCAD Scripting Basics.

To mirror objects use the mirror method of the Draft module.

mirrored_list = mirror(objlist, p1, p2)

• objlist contains the objects to be mirrored. It is either a single object or a list of objects.
• p1 is the first point of the mirror plane.
• p2 is the second point of the mirror plane.
• If the Draft working plane is available the alignment of the mirror plane is determined by its normal, else the view direction of the camera in the active 3D view is used. If the graphical interface is not available the Z axis is used.
• mirrored_list is returned with the new Part::Mirroring objects. It is either a single object or a list of objects, depending on objlist.

Example:

import FreeCAD as App
import Draft

doc = App.newDocument()

place = App.Placement(FreeCAD.Vector(1000, 0, 0), App.Rotation())
polygon1 = Draft.make_polygon(3, 750)
polygon2 = Draft.make_polygon(5, 750, placement=place)

p1 = App.Vector(2000, -1000, 0)
p2 = App.Vector(2000, 1000, 0)

line1 = Draft.make_line(p1, p2)
mirrored1 = Draft.mirror(polygon1, p1, p2)

Line2 = Draft.make_line(-p1, -p2)
mirrored2 = Draft.mirror([polygon1, polygon2], -p1, -p2)

doc.recompute()
