'Make a pattern from combinations of transformations' - The {{Button|[[Image:PartDesign_MultiTransform.png|16px|link=PartDesign_MultiTransform]] [[PartDesign_MultiTransform|MultiTransform]]}} tool takes one (or a set of) part 'features' as its input, and allows the user to apply multiple transformations to that feature (or set of features) progressively, in sequence - creating a combined or compound transformation.
The [[Image:PartDesign_MultiTransform.svg|24px]] '''PartDesign MultiTransform''' tool creates a pattern of one or more features. The pattern can include multiple transformations where each subsequent transformation is applied to the result of the previous transformation.

For example, to produce the flange with a double row of holes as pictured below, the user:
<!--T:42-->
#selected the hole as the 'feature' (base) in the Model tree
The available transformations are: [[Image:PartDesign_Mirrored.svg|16px|link=PartDesign_Mirrored]] [[PartDesign_Mirrored|Mirrored]], [[Image:PartDesign_LinearPattern.svg|16px|link=PartDesign_LinearPattern]] [[PartDesign_LinearPattern|LinearPattern]], [[Image:PartDesign_PolarPattern.svg|16px|link=PartDesign_PolarPattern]] [[PartDesign_PolarPattern|PolarPattern]] and [[Image:PartDesign_Scaled.svg|16px|link=PartDesign_Scaled]] [[PartDesign_Scaled|Scaled]]. The first three are also available as separate tools.
#clicked on the {{Button|[[Image:PartDesign_MultiTransform.png|16px|link=PartDesign_MultiTransform]] [[PartDesign_MultiTransform|MultiTransform]]}} icon
#added a linear pattern with two occurrences in the X direction

==Usage== <!--T:10-->
==Usage== <!--T:22-->
Before beginning any of the methods below, make sure the necessary {{Button|[[Image:PartDesign Body.png|16px|link=PartDesign_Body]] [[PartDesign_Body|Body]]}} object is [[PartDesign_Body#Usage_Notes|active]]; if not, you will receive a pop-up error message stating you need an active {{Button|[[Image:PartDesign Body.png|16px|link=PartDesign_Body]] [[PartDesign_Body|Body]]}} object before using the {{Button|[[Image:PartDesign_MultiTransform.png|16px|link=PartDesign_MultiTransform]] [[PartDesign_MultiTransform| MultiTransform]]}} tool.


===Standard Method=== <!--T:11-->
=== Create === <!--T:43-->
This method starts with no existing transformation features and no selections in the viewport or the Model object tree.<BR>When initiated and completed with this method, the {{Button|[[Image:PartDesign_MultiTransform.png|16px|link=PartDesign_MultiTransform]] [[PartDesign_MultiTransform | MultiTransform]]}} should correctly become the "Tip" of the Body object.


<!--T:12-->
<!--T:44-->
# Optionally [[PartDesign_Body#Active_status|activate]] the correct Body.
# Click on the {{Button|[[Image:PartDesign_MultiTransform.png|16px|link=PartDesign_MultiTransform]] [[PartDesign_MultiTransform| MultiTransform]]}} icon to initiate the operation.
# Optionally select one or more features in the [[Tree_view|Tree view]] or the [[3D_view|3D view]].
# You will be prompted with the '''Select feature''' window.<BR>From the list, select one initial feature to be used for the transformations and click OK to proceed.<BR>You may add additional features in the next step.[[Image:PartDesign-MultiTransform-Select_feature.png|center|300px]]
# There are several ways to invoke the tool:
# The '''Transformed features messages''' and '''MultiTransform parameters''' window will appear.<BR>You will see the label of the feature you selected in the feature list view, below the {{Button|Add feature}} and {{Button|Remove feature}} buttons.[[Image:PartDesign-MultiTransform-General.png|center|300px]]<BR>If you want to include additional features for the transformations, follow these instructions:
#* Press the {{Button|[[Image:PartDesign_MultiTransform.svg|16px]] [[PartDesign_MultiTransform|Create MultiTransform]]}} button.
## Click the {{Button|Add feature}} button in the transform tool
#* Select the {{MenuCommand|Part Design → Apply a pattern → [[Image:PartDesign_MultiTransform.svg|16px]] Create MultiTransform}} option from the menu.
## Switch to the Model tree view (Click on '''Model''' tab)
# If there is no active Body, and there are two or more Bodies in the document, the {{MenuCommand|Active Body Required}} dialog will open and prompt you to activate one. If there is a single Body it will be activated automatically.
## Select the feature you want to add, and make it visible(spacebar, '''''or''''' right-click and toggle visibility).<BR>'''Note:''' This will hide the previously visible feature.
# If no features were selected the {{MenuCommand|Select feature}} [[Task_panel|task panel]] opens: select one or more (hold down the {{KEY|Ctrl}} key) from the list and press the {{Button|OK}} button.
## Click on anything in 3D view (viewport).
# The {{MenuCommand|MultiTransform parameters}} [[Task_panel|task panel]] opens. See [[#Options|Options]] for more information.
## Click on '''Tasks''' tab in Combo View to return to '''MultiTransform parameters''' window.
# Press the {{Button|OK}} button at the top to finish.
## You should see the label of the recently selected feature appear in the feature list view.
# Below the feature list view is the '''Transformations''' list view. Within you should see the text, "''' ''Right-click to add'' '''".
# Add a transformation by right-clicking in the '''Transformations''' list view to display the options list.[[Image:PartDesign-MultiTransform-Transformations_Right_Click.png|center|300px]]
## Add the desired transformation by selecting it in the options list.
## The new transformation entry will appear in the '''Transformations''' list with corresponding settings appearing below the list.[[Image:PartDesign-MultiTransform-Transformations-add_linear_pattern.png|center|300px]]
## Adjust the settings for the new transformation. (''You will see the preview in the viewport.'')
## Click the {{KEY|OK}} button underneath these settings to save the new transformation.
# Continue to add transformations in the order you wish to apply them using Step 5 above.
# You may also edit, delete, and move (change the order of) the transformations as needed by right-clicking on a transformation in the '''Transformations''' list and selecting the corresponding option.
# When you are finished adding and editing the transformations, click the {{KEY|OK}} button at the very top to save the {{Button|[[Image:PartDesign_MultiTransform.png|16px|link=PartDesign_MultiTransform]] [[PartDesign_MultiTransform | MultiTransform]]}} and exit.


===Alternate Method 1=== <!--T:13-->
=== Edit === <!--T:45-->
This method starts with one existing transformation feature in the {{Button|[[Image:PartDesign Body.png|16px|link=PartDesign_Body]] [[PartDesign_Body|Body]]}} object.


<!--T:14-->
<!--T:46-->
# Do one of the following:
# In the Model tree, within the active Body object, select the existing transformation to be included.
#* Double-click the MultiTransform object in the [[Tree_view|Tree view]].
# Click on the {{Button|[[Image:PartDesign_MultiTransform.png|16px|link=PartDesign_MultiTransform]] [[PartDesign_MultiTransform| MultiTransform]]}} icon to initiate the operation.
#* Right-click the MultiTransform object in the [[Tree_view|Tree view]] and select {{MenuCommand|Edit MultiTransform}} from the context menu.
# In the feature list view, you will see the label(s) of the feature(s) from the existing transformation you included.<BR>To add additional features, see '''Step 3''' in the [[PartDesign_MultiTransform#Standard_Method|Standard Method]] above.
# The {{MenuCommand|MultiTransform parameters}} [[Task_panel|task panel]] opens. See [[#Options|Options]] for more information.
# Below the feature list view is the '''Transformations''' list view. Within you should see the label for the existing transformation you included.
# Press the {{Button|OK}} button at the top to finish.
# Finish using '''Steps 5-8''' in the [[PartDesign_MultiTransform#Standard_Method|Standard Method]] above.
When initiated and completed in this way, the {{Button|[[Image:PartDesign_MultiTransform.png|16px|link=PartDesign_MultiTransform]] [[PartDesign_MultiTransform | MultiTransform]]}} usually fails to become the "Tip" of the Body object. To correct this:
# Right click on the newly created {{Button|[[Image:PartDesign_MultiTransform.png|16px|link=PartDesign_MultiTransform]] [[PartDesign_MultiTransform | MultiTransform]]}}.
# Choose "'''Set tip'''".


===Alternate Method 2=== <!--T:15-->
=== Combine existing transformations === <!--T:47-->
This method starts with multiple existing, independent feature transformations in the {{Button|[[Image:PartDesign Body.png|16px|link=PartDesign_Body]] [[PartDesign_Body|Body]]}} object - with the idea of combining them. '''NOTE:''' to combine existing transformations, they must be within the same Body object and should all use the same feature or feature set in each.


<!--T:16-->
<!--T:48-->
It is possible to create a MultiTransform object from existing [[PartDesign_Mirrored|Mirrored]], [[PartDesign_LinearPattern|LinearPattern]] and [[PartDesign_PolarPattern|PolarPattern]] transformations.
# In the Model tree, within the active Body object, select one of existing transformation of those you wish to include.
# Click on the {{Button|[[Image:PartDesign_MultiTransform.png|16px|link=PartDesign_MultiTransform]] [[PartDesign_MultiTransform| MultiTransform]]}} icon to initiate the operation.
# Click the {{KEY|OK}} button at top to save and exit.
# In the object tree, select the newly created {{Button|[[Image:PartDesign_MultiTransform.png|16px|link=PartDesign_MultiTransform]] [[PartDesign_MultiTransform| MultiTransform]]}}.
# In the ''Property View'' window, locate the '''Transformations''' property in the ''Data'' tab.
# Edit the '''Transformations''' property by clicking on its value, then click on the ellipse box that appeared to open the '''Links''' window for this property.
# Select all existing feature transformations that should be included. Multiple selections are permitted using CTRL-click.
# Click {{KEY|OK}} to save and close the '''Links''' window.
# Click the {{Button|[[Image:Std_Refresh.png|16px|link=Std_Refresh]] [[Std_Refresh|Refresh]]}} button if activated.
When initiated and completed in this way, the {{Button|[[Image:PartDesign_MultiTransform.png|16px|link=PartDesign_MultiTransform]] [[PartDesign_MultiTransform| MultiTransform]]}} might fail to become the "Tip" of the Body object. If you need it to be the "Tip":
# Right click on the newly created {{Button|[[Image:PartDesign_MultiTransform.png|16px|link=PartDesign_MultiTransform]] [[PartDesign_MultiTransform| MultiTransform]]}}.
# If available, choose "'''Set tip'''".


===Usage Notes=== <!--T:17-->

A sketch modelling the full part with a single extrusion and no mirroring would be a lot more complex and all later changes would be more complicated.

Limitations

See PartDesign PolarPattern.

Example

You can use this tool to create a fully parametric part that is symmetrical about two axes from a sketch.

This could be a 150x100x10mm large mounting plate for a motor with symmetric holes.

  1. Create a Body and add a sketch on one of its base planes.
  2. In the sketch create geometry for one quadrant of the part (i.e. the upper right quadrant).
    • Note that the constraints must also only cover a quarter of the part, e.g. instead of the full dimension of 150mm enter 150/2mm or 75mm.
    • Make sure the sketch is closed by adding lines along the vertical and horizontal axes.
  3. Extrude the part with PartDesign Pad.
  4. Select PartDesign MultiTransform.
  5. The task dialog opens.
  6. The last feature of the Body is already selected. Since we want to mirror that feature we can ignore the Add feature and Remove feature buttons.
  7. Right-click in the Transformations field and select Add mirrored transformation from the context menu.
  8. For the Plane select Vertical sketch axis.
  9. If the Update view checkbox is checked, you should now see the part mirrored about one axis.
  10. Again select Add mirrored transformation from the context menu of the Transformations field.
  11. Now for the Plane select Horizontal sketch axis.
  12. Press the OK button to finish.
  13. To remove the edges along the axes of symmetry in the final result, set the DataRefine property of the new feature to true in the Property editor.

To verify that the part is fully parametric open the initial sketch with the quarter part and change one dimension, say a hole diameter. After closing the sketch the three other holes will have changed accordingly. This works with all other dimensions as well. A sketch modelling the full part with a single extrusion and no mirroring would be a lot more complex and all later changes would be more complicated.
