Extrude reference (Surface)
The Extrude command extrudes an open or closed sketch profile or planar face to create or modify a surface body in Fusion.
Note: When you invoke the Extrude command, and there is only one profile visible in your design, it is automatically selected.
Design > Surface > Create > Extrude 
Profile
Enables the selection of sketch profiles.
Distance
Specifies the distance to extrude. There are two distance fields for a two side extrusion.
Taper Angle
Specifies the angle to taper the extrusion.
Direction Type
Specifies the method to control the size of the extrusion.
- One Side Creates the extrusion in one direction.
- Two Side Creates the extrusion in both directions. Each direction can have a different extrusion length.
- Symmetric Creates the extrusion in both directions. Each direction has the same extrusion length.
Operation
Select an operation to control how the feature affects the design.
New Body: Creates a new body in the active component.
New Component: Creates a new body in a new component.
Extents
Specifies how the distance of the extrusion is determined.
- Distance The extrusion terminates at a specified distance.
- To The extrusion terminates on a selected face or plane.
- All The profile is extruded through all geometry.
Match Shape
Available when Extents is set to To. The extrusion terminates on faces adjacent to the selected face.
Flip
Available when Extents is set to All. Changes the direction of the extrusion.
