Description

The Draft Rotate command rotates or copies selected objects around a center point by a given angle. In subelement mode the command rotates selected points and edges, or copies selected edges, of Draft Lines and Draft Wires.

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 or Arch Workbench.

Rotating one object using a center reference point, from one reference angle to another angle

Usage

See also: Draft Snap and Draft Constrain.

  1. Optionally select one or more objects, or one or more subelements of Draft Lines or Draft Wires.
  2. There are several ways to invoke the command:
    • Press the Draft Rotate button.
    • Select the Modification → Rotate option from the menu.
    • Use the keyboard shortcut: R then O.
  3. If you have not yet selected an object: select an object in the 3D view.
  4. The Rotate task panel opens. See Options for more information.
  5. Pick the first point, the center of rotation, in the 3D view, or type coordinates and press the Enter point button.
  6. Pick the second point in the 3D view, or enter a Base angle.
  7. Pick the third point in the 3D view, or enter a Rotation.

Options

The single character keyboard shortcuts and the modifier key mentioned here can be changed. See Draft Preferences.

  • To manually enter the coordinates for the center of rotation 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.
  • The Relative checkbox has no purpose for this command.
  • 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. introduced in version 0.20
  • Press T or click the Continue checkbox to toggle continue mode. If continue mode is on, the command will restart after finishing. This mode really only makes sense if copy mode is switched on. Depending on the Select base objects after copying preference, either the original objects are selected for the next command call or the copies that were created last. See Preferences.
  • Press P or click the Copy checkbox to toggle copy mode. If copy mode is on, the command will create rotated copies instead of rotating the original objects.
  • Press D or click the Modify subelements checkbox to toggle subelement mode. If subelement mode is on, the command will rotate the selected subelements instead of the whole objects. The subelements must belong to Draft objects with a DataPoints property, such as Draft Wires.
  • If copy mode and subelement mode are both on, and edges of Draft Wires are selected, new wires will be created from those edges.
  • Holding down Alt after entering the Base angle will also toggle copy mode. While Alt is held down multiple points can be picked for the Rotation. Release Alt to finish the command and see the created copies.
  • Press Esc or the Close button to abort the command.

Notes

  • An Object that is attached cannot be rotated with the Draft Rotate command. To rotate it either its DataSupport object has to be rotated, or its DataAttachment Offset has to be changed.

Preferences

See also: Preferences Editor and Draft Preferences.

  • To change the number of decimals used for the input of coordinates and angles: Edit → Preferences... → General → Units → Units settings → Number of decimals.
  • To store and reuse the same copy mode setting across commands: Edit → Preferences... → Draft → General settings → Draft tools options → Global copy mode.
  • To reselect the base objects after copying objects: Edit → Preferences... → Draft → General settings → Draft tools options → Select base objects after copying.

Scripting

See also: Autogenerated API documentation and FreeCAD Scripting Basics.

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

rotated_list = rotate(objectslist, angle, center=Vector(0,0,0), axis=Vector(0,0,1), copy=False)
  • objectslist contains the objects to be rotated. It is either a single object or a list of objects.
  • angle is the angle of rotation in degrees.
  • center is the center point of rotation.
  • axis is the direction of the axis of rotation.
  • If copy is True copies are created instead of rotating the original objects.
  • rotated_list is returned with the original rotated objects, or with the new copies. It is either a single object or a list of objects, depending on objectlist.

Example:

import FreeCAD as App
import Draft

doc = App.newDocument()

polygon1 = Draft.make_polygon(3, radius=300)
Draft.move(polygon1, App.Vector(1000, 0, 0))

# Rotation around the origin
angle1 = 45
rot2 = Draft.rotate(polygon1, angle1, copy=True)
rot3 = Draft.rotate(polygon1, 2*angle1, copy=True)
rot4 = Draft.rotate(polygon1, 4*angle1, copy=True)

polygon2 = Draft.make_polygon(3, radius=1000)
polygon3 = Draft.make_polygon(5, radius=500)
Draft.move(polygon2, App.Vector(2000, 0, 0))
Draft.move(polygon3, App.Vector(2000, 0, 0))

# Rotation around another point
angle2 = 60
cen = App.Vector(3100, 0, 0)
list2 = [polygon2, polygon3]
rot_list2 = Draft.rotate(list2, angle2, center=cen, copy=True)
rot_list3 = Draft.rotate(list2, 2*angle2, center=cen, copy=True)
rot_list4 = Draft.rotate(list2, 4*angle2, center=cen, copy=True)
