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.

3. Select the type of reference:
◦ 
In Context—Creates the shrinkwrap in the context of the assembly.

◦ Outer shell—Use this method to collect only the outer surfaces of components to include in the Shrinkwrap. In an assembly, only outer surfaces of the assembly are collected, surfaces of inner components are ignored.
◦ Autocollect all solid geometry—Use this method to collect quilts or all the geometry bodies to include in the Shrinkwrap. In an assembly, you are prompted to include inner components in your selection.
◦ Manual collection—Use this method to manually collect surfaces to include in the Shrinkwrap.
5. Configure the options on the References and Options tabs using the procedures below for the selected collection method.
6. Click to complete the Shrinkwrap feature.

1. 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.
Click Details to open the Surface Sets dialog box.
For more information see the topic To Modify Rule-base Surface Sets in the Fundamentals area of the Help Center.
Subset3. Click Options to define Shrinkwrap settings:
◦ Surface Copying 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).
| | This option is recommended when working with an Automatic representation. During Shrinkwrap creation and redefinition, the required models are retrieved based on the defined subset only when the Shrinkwrap is created. |
▪ 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.
▪ 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.
▪ Include Construction Bodies—Include construction bodies 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. Click the box and select a model for the small surfaces.
◦ 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.
Autocollect all solid geometry
1. From the Collection method list, select Autocollect all solid geometry. The Exclude Internal Components message opens.
2. Make internal components available for selection:
◦ Yes—Includes internal components for selection.
◦ No—Excludes internal components from selection.
3. Click Options. The Options tab opens.
4. To fill holes, click in the collector and select the surface with the holes or cuts to fill.
5. To exclude holes from filling, clear the checkbox and remove the holes from the list that appears below the Fill holes collector.
6. To display a curve in place of the filled holes, select the Display curve in place of filled contour checkbox.
7. Under Resulting Geometry Type select the type of geometry you want to create.
◦ Quilts—The resulting geometry is created as quilts. You cannot solidify these quilts.
| | When you are creating the Shrinkwrap feature in an assembly, resulting geometry is created as quilts. |
◦ Bodies—The resulting geometry is created as bodies.
Select an option from the Copying Method list.
▪ Leave as separate objects if operation fails—Keep each body or quilt as a separate object.
▪ Merge—Merge bodies or quilts in an assembly. Choose a merge option:
▪ Merge all in part—Merge all bodies in each part. Every part will contain only one body that consists of all the bodies in the part.
▪ Merge all—Merge all the bodies or quilts in the model to one body or quilt. This is the only option when you create the Shrinkwrap feature in an assembly.
The Body Options tab becomes available. You can add the resulting geometry to an existing body or create a new body.
Leave as separate objects if operation fails—Keep the objects as separate bodies or quilts when the merge fails.
8. 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.
9. Click References and note that all solid references are included in the Shrinkwrap. Datums and annotations can be included.
| | You can exclude surfaces but be aware that when you select bodies as the resulting geometry, you most likely don’t want to exclude the surfaces of these bodies. |
Manual collection
Create a Shrinkwrap containing only the selected surfaces.
1. Click References.
2. Select the surfaces to include in the Shrinkwrap and to exclude from the Shrinkwrap.
3. Datums and annotations can be included.
