To Create a Shrinkwrap Feature
1. Retrieve an assembly or a part.
2. Click
Shrinkwrap. The
Shrinkwrap tab opens with the top-level assembly as the reference model.
|  All choices on the Shrinkwrap tab are optional. You can automatically create a Shrinkwrap feature containing default shrinkwrap information by clicking  . |
3. Select a collection method for the surface subset from the collection mode list:
◦ Outer Shell—Create a Shrinkwrap of the exterior shape of the model.
◦ Autocollect all solid surfaces—Create a Shrinkwrap containing the external and internal solid surfaces of the model. For a part, the following commands are available in the Options tab:
▪ Solidify resulting geometry—Create a solid Shrinkwrap.
▪ Leave as quilt if solidification fails—Restore the failed solid Shrinkwraps and create a quilt Shrinkwrap instead.
◦ Manual collection—Create a Shrinkwrap containing only the selected surfaces.
4. To include or exclude assembly components in the Shrinkwrap,
define a subset.
5. Click References and select additional shrinkwrap references:
◦ Always include surfaces—Include selected surface sets.
◦ Never include surfaces—Exclude selected surfaces.
◦ Chain—Include selected edges and curves.
◦ Include Datums—Include selected datums.
◦ Edit—Include selected annotation features.
6. Click Options to define shrinkwrap settings:
◦ Subset Options
▪ Shrinkwrap then Exclude (default)—Analyze the entire assembly to identify external surfaces. Only surfaces that belong to the selected components are included in the resulting Shrinkwrap feature (used with subsets).
▪ Exclude then Shrinkwrap—Base the Shrinkwrap only on the selected components (used with subsets).
◦ Quality
▪ Level—Enter a value (1–10) for the shrinkwrap quality level. The default setting is 1. The higher the quality, the higher the processing time.
◦ Attributes
▪ Auto Hole Filling—Fill all holes or cuts that intersect a single surface.
▪ Include Quilts—Include external quilts. Although quilt surfaces are considered for inclusion, not all are automatically included in the Shrinkwrap.
▪ Ignore Small Surfaces—Exclude surfaces smaller than the specified value (percentage of the model's size). Type a whole number (0 is the default) in the Threshold as percentage of model size box to specify the relative size of the surface to be ignored.
◦ Fill contours—Fill contours of the selected surface. Click a listed surfaces to view the contours it contains. You can set contour display as follows:
▪ Remove contours, select an individual contour, right-click and choose Remove from the shortcut menu. The contour is removed from the list and is not filled.
▪ Click or clear the Display curve in place of filled contour box.
◦ Copied Geometry Update—Set geometry dependency of the Shrinkwrap feature. The Shrinkwrap feature is dependent, by default, on the source components. If the size or position of the original component are changed, the Shrinkwrap feature updates accordingly.
▪ Automatic Update—Keeps the relationship between the current feature and the original geometry.
▪ Manual Update—Temporarily suspends the relationship between the current feature and the original geometry. If the original part changes, the current feature does not change.
▪ No Dependency—Breaks the relationship between the feature and the original geometry. If the original part changes, the current feature does not change. When there is a dependency to a reference model it is broken, similar to breaking dependency using the Global Reference Viewer.
