If there is no predefined transformation within the current [[Image:PartDesign_MultiTransform.svg|16px]] [[PartDesign_MultiTransform|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 recommendet to use '''Scaled''' as a single or a first transformation of a MultiTransform feature.

When creating or editing a Scaled object, the 'MultiTransform parameters' dialogue offers the following options:
* {{MenuCommand|Factor}}: The factor to which the last feature is scaled.

* {{MenuCommand|Occurrences}}: Number of steps from unscaled (1) to {{MenuCommand|Factor}} (including base and last feature).
===List of features===
** A scaled transformation accepts the number of occurrences of the previous transformation as maximum value or any integer divisor of that number returning an integer result. So {{Value|12}}, {{Value|6}}, {{Value|4}}, {{Value|3}}, and {{Value|2}} are valid for a Linear or Polar Pattern with 12 occurrences.

** A scaled single feature accepts any integer number larger than 1.
The list of base features that are handled by this MultiTransform object.

===List of transformations===

The list of transformations that are use by this MultiTransform object.
: See [[Image:PartDesign_MultiTransform.svg|16px]] [[PartDesign_MultiTransform#Usage|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.

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 increases or decreases until reaching the given value at 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 previous transformation within the MultiTransform feature, scaled items 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 the first transformation of a MultiTransform feature.

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

Usage

Scaling a transformed feature

  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.
  3. Right-click in the Transformations list and select Add scaled transformation from the context menu.
  4. A Scaled item is added to the list and the task panel is extended at the bottom to allow to set the Factor and Occurrences. See Options for more information.
  5. Press the OK bar at the bottom.
  6. Press the OK button at the top to finish.

Scaling a single feature

  1. Select a feature of the current body in the Tree view.
  2. Do one of the following:
    • Press the MultiTransform button.
    • Select the Part Design → Apply a pattern → Create MultiTransform option from the menu.
  3. The MultiTransform parameters task panel opens. See above.

Options

  • Factor: The factor to which the last feature is scaled.
  • Occurrences: Number of steps from unscaled (1) to Factor (including base and last feature).
    • A scaled transformation accepts the number of occurrences of the previous transformation as maximum value or any integer divisor of that number returning an integer result. So 12, 6, 4, 3, and 2 are valid for a Linear or Polar Pattern with 12 occurrences.
    • A scaled single feature accepts any integer number larger than 1.

Notes

  • The center of scaling is the features's center of gravity and that may cause:
    • A growing item to protrude on the opposite side of the parent feature.
    • A shrinking item to lose all contact with the parent feature and disappear.
    • A shrinking pocket to become an invisible cavity inside the parent feature.
