2. Chapter 5: Creating First/Base Feature of Solid Models
Once a sketch has been created and fully defined by using different sketching tools, you can convert the sketch into a solid feature by using the feature modeling tools. All the feature modeling tools are available in the Features CommandManager in the Part modeling environment.

3. Creating an Extruded Feature
Chapter 5: Creating First/Base Feature of Solid Models
Creating an Extruded Feature
An extruded feature is created by adding material normal or at an angle to the sketching plane. In SOLIDWORKS, you can create an extruded feature by using the Extruded Boss/Base tool.

4. Chapter 5: Creating First/Base Feature of Solid Models
After drawing the sketch, click on the Extruded Boss/Base tool in the Features CommandManager. The preview of the extruded feature by adding material normal to the sketching plane appears in the graphics area with the default extrusion parameters.

5. Chapter 5: Creating First/Base Feature of Solid Models
NOTE:
If you exit the Sketching environment after creating the sketch and the sketch has not been selected in the graphics area, then on invoking the Extruded Boss/Base tool, the Extrude PropertyManager appears. Also, you are prompted to select either a sketch to be extruded or a sketching plane to create a sketch.

6. Chapter 5: Creating First/Base Feature of Solid Models
The options in the Boss-Extrude PropertyManager are used to specify the parameters for the extruded feature. Some of this options are as follows:
From
The options in the Start Condition drop-down list of the From rollout are used to specify the start condition for the extruded feature.
Sketch Plane
By default, the Sketch Plane option is selected in the Start Condition drop-down list of the From rollout. As a result, extrusion starts exactly from the sketching plane of the sketch.

7. Chapter 5: Creating First/Base Feature of Solid Models
Offset
The Offset option is used to create an extruded feature at an offset distance from the sketching plane.
NOTE:
The Surface/Face/Plane and Vertex options of the Start Condition drop-down list are discussed in later chapters.

8. Chapter 5: Creating First/Base Feature of Solid Models
End Condition
The options in the End Condition drop-down list are used to define the end condition for the extruded feature.

9. Chapter 5: Creating First/Base Feature of Solid Models
The options of the End Condition drop-down list are as follows:
Blind
The Blind option of the End Condition drop-down list is used to specify the end condition of the extrusion by specifying the depth value in the Depth field of the Direction 1 rollout.

10. Chapter 5: Creating First/Base Feature of Solid Models
Mid Plane
The Mid Plane option of the End Condition drop-down list allows you to extrude the feature symmetrically about the sketching plane.
NOTE:
The other options such as Up To Vertex, Up To Surface, and Offset From Surface of the End Condition drop-down list are discussed in later chapters.

14. Chapter 5: Creating First/Base Feature of Solid Models
Direction 2
The options in the Direction 2 rollout are same as those in the Direction 1 rollout of the PropertyManager with the only difference that the options of the Direction 2 rollout are used to specify the end condition in the second direction of the sketching plane.

15. Chapter 5: Creating First/Base Feature of Solid Models
Thin Feature
The options in the Thin Feature rollout of the PropertyManager are used to create a thin solid feature of specified wall thickness.

16. Chapter 5: Creating First/Base Feature of Solid Models
One-Direction
By default, the One-Direction option is selected in the Type drop-down list. As a result, the thickness is added in one direction of the sketch.

17. Chapter 5: Creating First/Base Feature of Solid Models
Mid-Plane
The Mid-Plane option of the Type drop-down list is used to add thickness symmetrically on both sides of the sketch.
Two-Direction
The Two-Direction option is used to add different thickness in both the directions of a sketch.

18. Chapter 5: Creating First/Base Feature of Solid Models
NOTE:
You can create a thin feature from a closed or an open sketch.
Cap ends
The Cap ends check box is used to close the thin feature by adding caps on its both open ends.

19. Chapter 5: Creating First/Base Feature of Solid Models
Selected Contours
The Selected Contours rollout of the PropertyManager is used to select the contour or closed region of a sketch for extrusion.

20. Creating a Revolved Feature
Chapter 5: Creating First/Base Feature of Solid Models
Creating a Revolved Feature
A revolved feature is a feature created such that the material is added by revolving a sketch around an axis of revolution.

21. Chapter 5: Creating First/Base Feature of Solid Models
After drawing the sketch of a revolved feature and a centerline as the axis of revolution by using the sketching tools in the Sketching environment, do not exit the Sketching environment. Next, click on the Revolved Boss/Base tool. The preview of the revolved feature appears in the graphics area with default parameters. Also, the Revolve PropertyManager appears on the left of the graphics area.

22. Chapter 5: Creating First/Base Feature of Solid Models

If you exit the Sketching environment after creating the sketch of the revolved feature and the sketch is not selected in the graphics area, then on clicking the Revolved Boss/Base tool, the Revolve PropertyManager appears as shown in figure given below. Also, you are prompted to select either the sketch to be revolved in the graphics area or a sketching plane for creating the sketch.

23. Chapter 5: Creating First/Base Feature of Solid Models
The options in the Revolve PropertyManager are used to specify the parameters for the revolved feature.
Axis of Revolution
The Axis of Revolution field of the Axis of Revolution rollout is used to select the axis of revolution of the revolved feature.
Revolve Type
The Revolve Type drop-down list of the Direction 1 rollout is used to select a method for revolving the sketch.

24. Chapter 5: Creating First/Base Feature of Solid Models
The options of the Revolve Type drop-down list are as follows:
Blind
The Blind option of the Revolve Type drop-down list is used to define the end condition or termination of the revolved feature by specifying the angle of revolution.
Mid Plane
The Mid Plane option is used to revolve a sketch about a centerline, symmetrically in both sides of the sketching plane.
NOTE:
The Up To Vertex, Up To Surface, and Offset From Surface options of the Revolve Type drop-down list are discussed in the later chapters.

25. Chapter 5: Creating First/Base Feature of Solid Models
Reverse Direction
The Reverse Direction button of the rollout is used to reverse the direction of revolution from one side of the sketching plane to the other side.
Direction 2
The options in the Direction 2 rollout are same as those in the Direction 1 rollout of the PropertyManager with the only difference that the options of the Direction 2 rollout are used to specify the end condition of the revolved feature in the second direction of the sketching plane.
