Enclose

1. Click .

   

2. 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.

3. Click .

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.

If the selection of boundaries results in multiple solids, Onshape automatically combines the solids to form one part.

This lists the collection of surface feature tools. This is not an exhaustive list. Additional Feature tools may be used when modeling surfaces. See Surfacing for additional information.

• Thicken - Add depth to a surface. Create a new part or modify an existing one by giving thickness to a surface and converting it to a solid, adding or removing material from an existing part or surface, or intersecting parts in its path.
• Enclose - 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.
• Fillet - Round sharp interior and exterior edges and define as a standard constant radius, more stylized conic, or variable by selecting Edge fillet. Optionally apply a Full round fillet to create a seamless blend of one or more faces between two opposing sides.
• Face blend - Round sharp connected or disconnected interior and exterior faces to create a seamless blend between the faces or detach the blend to create new faces, defining a radius or constant width. Further define the blend cross section (rolling ball or swept profile), symmetry, control, trim, constraints, and limits.
• Delete face - Remove geometry from a part. Select whether to heal the surrounding faces (by extending until they intersect), cap the void, or leave the void open. This Direct Editing tool is especially convenient if you don't have the parametric history of the part, as is often the case with an imported part.
• Move face - Translate, rotate, or offset one or more selected faces. This Direct Editing tool is especially convenient if you don't have the parametric history of the part, as is often the case with an imported part.
• Replace face - Trim a face or extend a face to a new surface. This Direct Editing tool is especially convenient if you don't have the parametric history of the part, as is often the case with an imported part.
• Offset surface - Create a new surface by offsetting an existing face, surface, or sketch region. Set offset distance to 0 to create a copy in place.
• Boundary surface - Create or add a surface specified by its boundary profiles.
• Fill - Create a surface (or a part from surfaces) by defining boundaries and refine the surface with boundary conditions (instead of requiring the use of reference surfaces).
• Move boundary - Move boundary edges of a surface in order to extend or trim it.
• Ruled surface - Create a new or additional ruled surface from an existing edge or multiple edges of a sketch region.
• Mutual trim - Trim two adjacent surfaces by extending intersections to complete the trim.
