Extrude is one of the most commonly used features in SolidWorks, which allows users to create a 3D solid or surface by extending a sketch along a direction. Essentially, the extrude feature takes a 2D sketch and turns it into a 3D object by adding depth to the sketch in a specified direction.
To use the extrude feature in SolidWorks, first, you need to create a sketch on a selected plane. Once the sketch is created, you can select the extrude command from the toolbar or from the extrude button in the Command Manager.
The extrude feature can be used to create a wide range of 3D shapes and objects, including basic prisms, cylinders, and cubes, as well as more complex shapes like curved surfaces and intricate geometries. By using different options and configurations, you can modify the basic extrude feature to create more complex and customized shapes.
