The Extrude command in SOLIDWORKS is used to create a 3D solid or surface by extending a 2D sketch in a specific direction.

• Extrude is a fundamental feature in SOLIDWORKS used for creating solid models.

• It allows you to add or remove material from a sketch to create a 3D shape.

• The command offers options for specifying the direction, depth, and other parameters of the extrusion.

• You can extrude a sketch symmetrically, asymmetrically, or up to a selected surface.

• Examples: creating...read more
