About Patterning, Mirroring, or Moving Features with Asynchronous Datums

You can create asynchronous datum features as references while patterning, mirroring, or moving features. The asynchronous datums that are created are embedded in the features that are patterned, mirrored, or moved. Additionally, the features that are patterned, mirrored, or moved may also include embedded datum features.

While patterning, mirroring, or moving:

• The datum features embedded in the main feature are also duplicated and their instances created, but without transformations.

• The instances of the datum features without transformations retain their relevant embedded locations in the resultant patterned, mirrored, or moved and transformed instances of the main feature.

• The locations of the duplicated datum features in the instances of the main feature are similar to the locations of the datum features that are embedded in the main feature.

• The patterned, mirrored, or moved instances of the main feature reference their relevant and corresponding duplicated datums in the cosmetic group header.

If you drag these embedded datums outside the patterned, mirrored, or moved group, the resultant patterned, mirrored, or moved instances lose the display of the cosmetic group.

While creating a pattern of a feature, you can select an existing datum feature as the pattern reference. After patterning, you can drag and drop the reference datum feature into the pattern header. You cannot drag or move the dragged and dropped datum feature that is embedded in the pattern header out of the pattern header. The patterned instances form a cosmetic feature group, and the Model Tree displays this group as a feature node with the patterned instances as the sub-nodes.

Alternatively, you can asynchronously create a reference datum feature while patterning a feature, especially for pattern types, such as direction and axis, that require datum features as references. The patterned instances form the cosmetic group referencing the datums embedded in the cosmetic pattern header.

While redefining a patterned feature with embedded datums, if you use the dimension of an embedded datum as the reference for patterning and if the embedded datum is not referenced, then you are prompted to confirm whether you want to abort the redefinition process.

If the original feature is a pattern and has a reference datum embedded in its pattern header with datums embedded in its individual pattern members, and if you are creating a pattern of a pattern:

• The first-level datums that are embedded in the pattern leader of the original pattern are not instanced or duplicated.

• All intermediary or second-level embedded datums are duplicated without transformations. The duplicated datums retain their relevant embedded locations. You cannot drag the duplicated embedded datums out of their relevant cosmetic groups.
