Description

The Draft Scale command scales or copies selected objects around a base point. In subelement mode the command scales selected points and 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, PartDesign Workbench or Arch Workbench.

Scaling an object around a base point

Usage

See also: Draft Snap and Draft Constrain.

Optionally select one or more objects, or one or more subelements of Draft Lines or Draft Wires.
There are several ways to invoke the command:
- Press the Draft Scale button.
- Select the Modification → Scale option from the menu.
- Use the keyboard shortcut: S then C.
If you have not yet selected an object: select an object in the 3D view.
The Scale task panel opens. See Options for more information.
If subelements have been selected: check the Modify subelements checkbox to switch on subelement mode.
Pick the base point in the 3D view, or type coordinates and press the Enter point button.
Enter the X, Y and Z scale factors.
Press Enter or the OK button to finish the command.

Options

First task panel

The single character keyboard shortcuts mentioned here can be changed. See Draft Preferences.

To manually enter the coordinates for the base point 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 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
The other checkboxes in this task panel, displayed in FreeCAD version 0.19 and earlier, are ignored by the command.
Press S to switch Draft snapping on or off.
Press the Close button to abort the command.

Second task panel

Enter the X, Y and Z factors to define the scaling. The values must be larger than zero.
Check the Uniform scaling checkbox to lock the X, Y and Z factors to the same value. In FreeCAD version 0.19 and earlier for this setting to take effect one of the scale factors has to be changed.
If the Working plane orientation checkbox is checked the scale factors are relative to the working plane coordinate system, else they are relative to the global coordinate system.
If the Copy checkbox is checked a scaled copy of the original object is created. This only works for Draft objects that have a VeriPoints property, such as Draft Wires.
If the Modify subelements checkbox is checked the command will use the selected subelements instead of the whole objects. The subelements must belong to Draft Lines or Draft Wires.
If the Create a clone checkbox is checked scaled clones of the original objects are created. This works for all object types. For objects that are not Draft objects, or for Draft objects that do not have a VeriPoints property, this option must be selected.
Press the Pick from/to points button and pick two additional points in the 3D view to calculate the scale factors. This will automatically check the Uniform scaling checkbox. The X, Y and Z scale factors will therefore be equal and will be set to the distance between the base point and the 'from' point, divided by the distance between the base point and the 'to' point.
Press Esc or the Cancel button to abort the command.

Notes

The command can also scale Image Planes, but not in clone mode.

Preferences

See also: Preferences Editor and Draft Preferences.

To change the number of decimals used for the input of scale factors (introduced in version 0.20) and coordinates: Edit → Preferences... → General → Units → Units settings → Number of decimals.
To change the number of decimals used for the input of scale factors (version 0.19 and below): Edit → Preferences... → Draft → General settings → General Draft Settings → Internal precision level.
To reselect the base objects after copying objects: Edit → Preferences... → Draft → General settings → Draft tools options → Select base objects after copying.

Scripting

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

scaled_list = scale(objectslist, scale=Vector(1,1,1), center=Vector(0,0,0), copy=False)

objectslist contains the objects to be scaled. It is either a single object or a list of objects.
scale is the vector that specifies by the X, Y and Z scale factors.
center is the center point of the scaling operation.
If copy is True copies are created instead of scaling the original objects.
scaled_list is returned with the original scaled objects, or with the new copies. It is either a single object or a list of objects, depending on objectslist.

Example:

import FreeCAD as App
import Draft

doc = App.newDocument()

pts = [App.Vector(0, 0, 0), App.Vector(500, 500, 0), App.Vector(600, 0, 0)]
wire1 = Draft.make_wire(pts, closed=True)
doc.recompute()

scale1 = App.Vector(2.3, 0.75, 0)
wire2 = Draft.scale(wire1, scale1, copy=True)
doc.recompute()

scale2 = App.Vector(-2, -1.5, 0)
wires = Draft.scale([wire1, wire2], scale2, copy=True)
doc.recompute()

 ==Description==
-The Scale tool scales or copies selected objects around a base point.
+The [[Image:Draft_Scale.svg|24px]] '''Draft Scale''' command scales or copies selected objects around a base point. In subelement mode the command scales selected points and edges of [[Draft_Line|Draft Lines]] and [[Draft_Wire|Draft Wires]].
+The command can be used on 2D objects created with the [[Draft_Workbench|Draft Workbench]] or [[Sketcher_Workbench|Sketcher Workbench]], but also on many 3D objects such as those created with the [[Part_Workbench|Part Workbench]], [[PartDesign_Workbench|PartDesign Workbench]] or [[Arch_Workbench|Arch Workbench]].
-The Scale tool can produce a copy or a [[Draft Clone|Draft Clone]] at a defined scale. Use [[Draft Offset|Draft Offset]] to produce a scaled copy of a wire set at a certain offset. A simple copy with no scaling can be produced with [[Draft Move|Draft Move]].
+[[Image:Draft_Scale_example.png|400px]]
-This tool can be used on 2D shapes created with the [[Draft Workbench|Draft Workbench]] but can also be used on many types of 3D objects such as those created with the [[Part Workbench|Part Workbench]] or [[PartDesign Workbench|PartDesign Workbench]].

+#* Use the keyboard shortcut: {{KEY|S}} then {{KEY|C}}.
+# If you have not yet selected an object: select an object in the [[3D_view|3D view]].
+# The {{MenuCommand|Scale}} task panel opens. See [[#Options|Options]] for more information.
+# If subelements have been selected: check the {{MenuCommand|Modify subelements}} checkbox to switch on subelement mode.
+# Pick the base point in the [[3D_view|3D view]], or type coordinates and press the {{Button|[[Image:Draft_AddPoint.svg|16px]] Enter point}} button.
+# Enter the X, Y and Z scale factors.
+# Press {{KEY|Enter}} or the {{Button|OK}} button to finish the command.
 ==Options==
+===First task panel===
-* To enter coordinates manually, simply enter the numbers, then press {{KEY|Enter}} between each X, Y and Z component. You can press the {{Button|[[Image:Draft_AddPoint.svg|16px]] [[Draft_AddPoint|add point]]}} button when you have the desired values to insert the point.
-* Fill in the X, Y and Z factors to define the scaling along that direction.
+The single character keyboard shortcuts mentioned here can be changed. See [[Draft_Preferences|Draft Preferences]].
-** Click the "Uniform scaling" checkbox to lock the X, Y and Z factors to the same value.
-** Click the "Working plane orientation" checkbox to lock the X, Y and Z scaling along the current [[Draft SelectPlane|Working Plane]]; otherwise, global X, Y and Z directions are used.
+* To manually enter the coordinates for the base point enter the X, Y and Z component, and press {{KEY|Enter}} after each. Or you can press the {{Button|[[Image:Draft_AddPoint.svg|16px]] Enter point}} button when you have the desired values. It is advisable to move the pointer out of the [[3D_view|3D view]] before entering coordinates.
-* Three options control the result of the scaling operation:
+* Press {{KEY|G}} or click the {{MenuCommand|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 [[Draft_SelectPlane|working plane]] coordinate system. {{Version|0.20}}
-** Create a clone. A [[Draft Clone|Draft Clone]] of the original object will be created. This will work for all object types.
+* The other checkboxes in this task panel, displayed in FreeCAD version 0.19 and earlier, are ignored by the command.
-::{{Emphasis|Note:}} even if the scaling factors are left at their default values (1.0, 1.0, 1.0), once the clone is created you will be able to change these factors manually in the [[property editor|property editor]].
+* Press {{KEY|S}} to switch [[Draft_Snap|Draft snapping]] on or off.
-:* Modify original. The original object will have its size modified. This will only work with [[Draft Workbench|Draft]] objects and non-parametric [[Part Workbench|Part]] shapes.
+* Press the {{Button|Close}} button to abort the command.
-:* Create a copy. A scaled copy of the original object will be created. This will work for all object types, but only the copies of [[Draft Workbench|Draft]] objects will be parametric.
-::{{Emphasis|Note:}} a copy is a completely different object from the original shape; it will be created at the specified scale, and then will have its own set of properties. On the other hand, a [[Draft Clone|Draft Clone]] is linked to the original shape and the only property that can be changed is the scale.
+===Second task panel===
+* Enter the X, Y and Z factors to define the scaling. The values must be larger than zero.
+* Check the {{MenuCommand|Uniform scaling}} checkbox to lock the X, Y and Z factors to the same value. In FreeCAD version 0.19 and earlier for this setting to take effect one of the scale factors has to be changed.
+* If the {{MenuCommand|Working plane orientation}} checkbox is checked the scale factors are relative to the [[Draft_SelectPlane|working plane]] coordinate system, else they are relative to the global coordinate system.
+* If the {{MenuCommand|Copy}} checkbox is checked a scaled copy of the original object is created. This only works for Draft objects that have a {{PropertyData|Points}} property, such as [[Draft_Wire|Draft Wires]].
+* If the {{MenuCommand|Modify subelements}} checkbox is checked the command will use the selected subelements instead of the whole objects. The subelements must belong to [[Draft_Line|Draft Lines]] or [[Draft_Wire|Draft Wires]].
+* If the {{MenuCommand|Create a clone}} checkbox is checked scaled [[Draft_Clone|clones]] of the original objects are created. This works for all object types. For objects that are not Draft objects, or for Draft objects that do not have a {{PropertyData|Points}} property, this option {{Emphasis|must}} be selected.
+* Press the {{Button|Pick from/to points}} button and pick two additional points in the [[3D_view|3D view]] to calculate the scale factors. This will automatically check the {{MenuCommand|Uniform scaling}} checkbox. The X, Y and Z scale factors will therefore be equal and will be set to the distance between the base point and the 'from' point, divided by the distance between the base point and the 'to' point.
+* Press {{KEY|Esc}} or the {{Button|Cancel}} button to abort the command.
+==Notes==
+* The command can also scale [[Image_CreateImagePlane|Image Planes]], but not in clone mode.
+==Preferences==
+See also: [[Preferences_Editor|Preferences Editor]] and [[Draft_Preferences|Draft Preferences]].
+* To change the number of decimals used for the input of scale factors ({{Version|0.20}}) and coordinates: {{MenuCommand|Edit → Preferences... → General → Units → Units settings → Number of decimals}}.
+* To change the number of decimals used for the input of scale factors ({{VersionMinus|0.19}}): {{MenuCommand|Edit → Preferences... → Draft → General settings → General Draft Settings → Internal precision level}}.
+* To reselect the base objects after copying objects: {{MenuCommand|Edit → Preferences... → Draft → General settings → Draft tools options → Select base objects after copying}}.

+scaled_list = scale(objectslist, scale=Vector(1,1,1), center=Vector(0,0,0), copy=False)
 }}
-* Scales the objects in {{incode|objectslist}} by the factors specified by the components of {{incode|delta}}, defined as a {{incode|FreeCAD.Vector}}, and using {{incode|center}} as base point.
+* {{incode|objectslist}} contains the objects to be scaled. It is either a single object or a list of objects.
-** {{incode|objectslist}} is either a single object or a list of objects.
+* {{incode|scale}} is the vector that specifies by the X, Y and Z scale factors.
-* If {{incode|copy}} is {{incode|True}} copies are created instead of modifying the original objects.
+* {{incode|center}} is the center point of the scaling operation.
-* If {{incode|legacy}} is {{incode|True}}, direct copy mode is used (outdated), otherwise a parametric copy is made.
+* If {{incode|copy}} is {{incode|True}} copies are created instead of scaling the original objects.
-* {{incode|scaledlist}} is returned with the original scaled objects, or with the new clones.
+* {{incode|scaled_list}} is returned with the original scaled objects, or with the new copies. It is either a single object or a list of objects, depending on {{incode|objectslist}}.
