Enclose
This functionality is available on Onshape's browser, iOS, and Android platforms.
Create a part by selecting all boundaries surrounding an empty space to form a solid. Use any set of surfaces and solids (including planes and faces) that intersect each other or connect at a boundary to create a volume.

In the Feature toolbar:

Enclose creates a part by selecting all boundaries surrounding an empty space to form a solid. Use any set of surfaces and solids (including planes and faces) that intersect each other or connect at a boundary to create a volume.
Click the Enclose feature tool on the Part Studio toolbar. Select the entities to enclose in the graphics area.
When Keep tools is selected, the surfaces remain and the volume is a solid part. Clicking Keep tools allows you to keep the surface. Deselecting keep tools removes the surface and keeps the part.
Click the checkmark to accept the Enclose feature.
Steps
- Click

-
Select the entities that surround the volume to be enclosed. Entities must intersect.
Optionally select Keep tools to retain the selected entities at the creation of the new part. If Keep tools is not selected, those owning parts of any selection (not from a sketch or a plane) will be deleted.

Examples
In the first image, the surfaces and the plane are selected as boundaries. In the second image, the surfaces are deleted (no Keep tools) and the volume bounded by the plane and surfaces is now a solid part.
Keep tools
When Keep tools is selected, the surfaces remain and the volume is a solid part.
Tip
If the selection of boundaries results in multiple solids, Onshape automatically combines the solids to form one part.
