Description

'Make a pattern from combinations of transformations' - The 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.

For example, to produce the flange with a double row of holes as pictured below, the user:

  1. selected the hole as the 'feature' (base) in the Model tree
  2. clicked on the MultiTransform icon
  3. added a linear pattern with two occurrences in the X direction
  4. added a polar pattern with eight occurrences around the Y axis.

Flange with double row of holes. Hole pattern created with 'MultiTransform' tool.

Usage

Create

  1. Optionally activate the correct Body.
  2. Optionally select one or more features in the Tree view or the 3D view.
  3. There are several ways to invoke the tool:
    • Press the MultiTransform button.
    • Select the Part Design → Apply a pattern → MultiTransform option from the menu.
  4. If there is no active Body, and there are two or more Bodies in the document, the Active Body Required dialog will open and prompt you to activate one. If there is a single Body it will be activated automatically.
  5. If no features were selected the Select feature task panel opens: select one or more (hold down the Ctrl key) from the list and press the OK button.
  6. The MultiTransform parameters task panel opens. See Options for more information.
  7. Press the OK button at the top to finish.

Edit

  1. Do one of the following:
    • Double-click the MultiTransform object in the Tree view.
    • Right-click the MultiTransform object in the Tree view and select Edit MultiTransform from the context menu.
  2. The MultiTransform parameters task panel opens. See Options for more information.
  3. Press the OK button at the top to finish.

Combine existing transformations

It is possible to create a MultiTransform object from existing Mirrored, LinearPattern and PolarPattern transformations.

  1. Check the DataOriginals property of the existing transformations to make sure they have been applied to the same features.
  2. Select those features in the Tree view.
  3. There are several ways to invoke the tool:
    • Press the MultiTransform button.
    • Select the Part Design → Apply a pattern → MultiTransform option from the menu.
  4. The MultiTransform parameters task panel opens.
  5. Press the OK button at the top.
  6. Edit the DataTranformations property of the create MultiTransform object:
    1. Click in the field.
    2. Press the ... button that appears.
    3. The Link dialog opens.
    4. Hold down the Ctrl key and select the existing transformations.
    5. Press the OK button.

Options

  • To add features:
    1. Press the Add feature button.

    1. Press the Remove feature button.
    2. Do one of the following:
      • Select a feature in the Tree view or the 3D view.
      • Select a feature in the list and press the Del key.
      • Right-click a feature in the list and select Remove from the context menu.
    3. Repeat to remove more features.
  • To add transformations:
    1. Right-click the Transformations list.
    2. Select one the available options from the context menu:

    4. Adjust the settings to suit.
    5. Press the OK bar at the bottom.
    6. Repeat to add more transformations.
  • To edit a transformation:

    3. Adjust the settings to suit.
    4. Press the OK bar at the bottom.
  • To change the order of the transformations:
