PartDesign MultiTransform

Introduction
'Make a pattern from combinations of transformations' - The  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) started by clicking on the  icon
 * 2) selected the hole as the 'feature' (base)
 * 3) added a linear pattern with two occurrences in the X direction
 * 4) added a polar pattern with eight occurrences around the Y axis.

Options
{| When creating a multitransform feature, the 'multitransform parameters' dialogue offers two different list views.
 * [[Image:Multitransfrom_parameters.png|left]]

Select originals
The list view shows the 'originals', the features that are to be patterned. Clicking on any feature will add it to the list.

Select transformations
This list can be filled with a combination of the simple transformations mirrored, linear pattern, polar pattern and scaled. The transformations will be applied one after the other. The context menu offers the following entries:

Edit
Allows editing the parameters of a transformation in the list (double-clicking will have the same effect)

Delete
Removes a transformation from the list

Add transformation
Adds a transformation to the list

Move Up/Down
Allows changing the order of transformations in the list

Limitations

 * A scaled transformation should not be the first in the list
 * The scaled transformation must have the same number of occurrences as the transformation immediately preceding it in the list
 * For further limitations, see the linear pattern feature

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. The pocket was first mirrored on the YZ plane and then patterned with two linear patterns to give a rectangular pattern.
