- Extend Surface
You can extend a surface by selecting an edge, multiple edges, or a face.
- Fillet Surface
You can use a fillet to smooth the edge between two adjacent faces in a surface body that meet at an angle.
- Knit Surface
Use the Knit Surface 
tool to combine two or more faces and surfaces into one.
- Mid Surface
The Mid-Surface 
tool enables you to create mid surfaces between suitable selected face pairs on solid bodies. Suitable face pairs should be offset from each other.
- Filled Surface
The Filled Surface 
feature constructs a surface patch with any number of sides, within a boundary defined by existing model edges, sketches, or curves, including composite curves.
- Trim Surface
You can use a surface, plane, or sketch as a trim tool to trim intersecting surfaces. You can also use a surface in conjunction with additional surfaces, as mutual trim tools. Trim surface includes the following options:
- Untrim Surface
With Untrim Surface, you can patch surface holes and external edges by extending an existing surface along its natural boundaries.
- Hide and Show Bodies
With multibody parts, you can hide or show surface or solid bodies using .
- Flatten Surface
SOLIDWORKS can any face, surface, or set of faces to create templates for manufacturing. This is useful when working with developable surfaces such as sheet metal parts with non-standard bends.
- Move/Copy Bodies
In multibody parts, you can move, rotate, and copy solid and surface bodies, or place them using mates.
- Move Face PropertyManager
You can offset, translate, and rotate faces and features directly on solid or surface models.
- Delete Face
- Delete Hole
The Delete Hole dialog box lists any closed profile instances previously deleted from a surface. It allows you to remove one or more instances, without deleting the entire Delete Hole feature from the FeatureManager design tree.
- Replace Face
You can replace faces in a surface or solid body with new surface bodies using the Replace Face 
tool (Surfaces toolbar).
