PartDesign MultiTransform

Introduction
'Make a pattern from combinations of transformations' - This tool takes a set of one or more selected features as its input (the 'originals'), and allows to apply several transformations in sequence to them. For example, to produce a flange with a double row of holes, the hole (the 'original') is first patterned in a linear pattern in the X direction, and then patterned eight times in a polar pattern around the Y axis.

Options
When creating a multitransform feature, the 'multitransform parameters' dialogue offers two different list views.

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.
