Description

PartDesign Scaled is one of the transformation options of MultiTransform. Contrary to the other options it is not available as a separate tool. It turns a transformation result into a sequence of scaled objects with evenly distributed scale factors. Starting with the unscaled base feature of the previous transformation the scale factor is increases or decreases until reaching the given value on the last item.

A linear pattern and a polar pattern → Scaled the linear pattern with 3 steps (occurrences) and the polar pattern with 12 steps

If there is no predefined transformation within the MultiTransform feature, a scaled item will be placed at the same position as the base feature. This may result in unexpected shapes if the base feature isn't covered completely by the scaled object. And thus it is not recommended to use Scaled as a single or a first transformation of a MultiTransform feature.

A base feature with a hole → Scaled object with 2 occurrences → Scaled object with 4 occurrences

Usage

Scaling transformed features

  1. There are two ways to reopen a MultiTransform feature in the Tree view:
    • Right-click on the tree item and select Edit MultiTransform from the context menu.
    • Double-cklick on the tree item.
  2. The MultiTransform parameters dialog will open in the Task panel.
  3. Right-click in the Transformations list view and select Add scaled transformation from the context menu.
  4. A Scaled item is added to the Transformations list and the dialog will be extended at the bottom to allow to set the options Factor and Occurrences.
  5. Click the OK bar at the bottom to validate the options.
  6. Click the OK button at the top to close the MultiTransform parameters dialog.

Scaling a single feature

  1. Select a feature of the current body in the Tree view.
  2. There are two ways to create a MultiTransform feature:
    • Press the text-top=MultiTransform MultiTransform button.
    • Select the Part Design → Apply a pattern → Create MultiTransform option from the menu.
  3. The MultiTransform parameters dialog will open in the Task panel.
  4. Right-click in the Transformations list view and select Add scaled transformation from the context menu.
  5. A Scaled item is added to the Transformations list and the dialog will be extended at the bottom to allow to set the options Factor and Occurrences.
  6. Click the OK bar at the bottom to validate the options.
  7. Click the OK button at the top to close the MultiTransform parameters dialog.


Options

When creating or editing a Scaled object, the 'MultiTransform parameters' dialogue offers the following options:

List of features

The list of base features that are handled by this MultiTransform object.

See MultiTransform, Usage for details about adding and removing features.

List of transformations

The list of transformations that are use by this MultiTransform object.

See MultiTransform, Usage for details about adding and removing transformations.

Parameters

  • Factor: The factor to which the last feature is to be scaled.
  • Occurrences: Number of steps from unscaled (1) to Factor (including base and last feature).
    • Scaled transformations accept the number of occurrences of the predefined transformation as maximum value or any integer divisor of that number returning integer results. (12, 6, 4, 3, or 2 for 12 occurrences of a Linear or Polar Pattern)
    • Scaled single features accept any integer number larger than 1.

Notes

  • The centre of scaling is the item's centre of gravity and that may cause:
    • An item that is growing through the parent feature.
    Protruding geometry on the opposite side is not trimmed automatically.
    • A shrinking item that is losing the contact with the parent feature.
    A fully detached item just disappears.
    • A shrinking pocket that is hiding invisible inside the parent feature.
    Void spaces inside are hard to detect.
