PartDesign Scaled

Description
The PartDesign Scaled command turns a set of transformation results within a  MultiTransform feature into a sequence of scaled objects with evenly distributed scale factors. Starting with the unscaled base feature of the predefined transformation the scale factor is growing/declining until reaching the given value on the last item.



If there is no predefined transformation within the current 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.



This command is not available from the menu nor does it have its own toolbar icon. It is incorporated into the  MultiTransform tool.

Scaling transformed features

 * 1) There are two ways to reopen a [[Image:PartDesign_MultiTransform.svg|16px]] MultiTransform feature in the Tree view:
 * 2) * Right-click on the tree item and select Edit MultiTransform from the context menu.
 * 3) * Double-cklick on the tree item.
 * 4) The MultiTransform parameters dialog will open in the Task panel.
 * 5) Right-click in  the Transformations list view and select Add scaled transformation from the context menu.
 * 6) 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.
 * 7) Click the  bar at the bottom to validate the options.
 * 8) Click the  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 [[Image:PartDesign_MultiTransform.svg|16px]] MultiTransform feature:
 * 3) * Press the button.
 * 4) * Select the option from the menu.
 * 5) The MultiTransform parameters dialog will open in the Task panel.
 * 6) Right-click in  the Transformations list view and select Add scaled transformation from the context menu.
 * 7) 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.
 * 8) Click the  bar at the bottom to validate the options.
 * 9) Click the  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 [[Image:PartDesign_MultiTransform.svg|16px]] MultiTransform, Usage for details about adding and removing features.

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

Limitations

 * See linear pattern feature for other limitations
 * See MultiTransform for more details

Examples
The smallest pad was first patterned three times in X direction and then scaled to factor two (so the three occurrences have scaling factor 1.0, 1.5 and 2.0). Then a polar pattern was applied with 8 occurrences.

Since the scaling is done with respect to the center of gravity, in the case of a pad, it is necessary that the pad penetrate also in the main body, otherwise the scaled objects are floating, detached from the body. To have a pad that intersects the main body can be used "two dimensions" type or "symmetric to plane" option.
