1. SolidWorks Session 2 Ferdowsi University of Mashhad Dr. Behnam Moetakef Imani Winter 2011

2. What is Sketch? The sketch is the basis for a 3D model. You can create a sketch on any of the default planes (Front Plane, Top Plane, and Right Plane)

3. Sketch Snaps

4. Arc typesTool Arc properties Centerpoint Arc Sketches arcs from a centerpoint, a start point, and an end point. Tangent ArcSketches arcs that are tangent to sketch entities. 3 Point ArcSketches arcs by specifying three points (start, end, and midpoint)

5. Circle

6. Line & Point

7. Polygon

9. Sketch Tools : Fillets

10. Sketch Tools : Chamfer

11. Sketch Tools : Offset & Convert Entity

12. Sketch Tools : Trim Entities

13. Sketch Tools : Extend Entities

14. Sketch Tools : Split Entities

15. Sketch Tools : Mirror

16. Sketch Tools: Move or Copy

17. Sketch Tools: Rotate

18. Sketch Tools: Scale

19. Sketch Tools : Linear Pattern

20. Sketch Tools : Circular Pattern 1

21. Sketch Tools : Circular Pattern 2

22. The Status of a Sketch Under defined –Additional dimensions or relations are required. –Under defined sketch entities are blue (by default). Fully defined –No additional dimensions or relationships are required. –Fully defined sketch entities are black (by default). Over defined –Contains conflicting dimensions or relations, or both. –Over defined sketch entities are red (by default).

23. Dimension : Smart Dimension

24. Relations :

25. Relations

26. Coincident –A point and a line, arc, or ellipse. –The point lies on the line, arc, or ellipse Merge Points –Two sketch points or endpoints. –The two points are merged into a single point.

27. Sketch the 2D profile Extrude the sketch Resulting base feature To Create an Extruded Base Feature: 1.Select a sketch plane. 2.Sketch a 2D profile. 3.Extrude the sketch perpendicular to sketch plane. Select the sketch plane

28. To Create a Revolved Base Feature: 1.Select a sketch plane. 2.Sketch a 2D profile. 3.Sketch a centerline (optional). 4.Revolve the sketch around a sketch line or centerline. Centerline (optional)

29. To Create a Sweep Feature 1.Sketch a Profile 2.Sketch a Path 3.Sweep the profile along the path

30. To Create a Loft Feature 1.Sketch a Series of Profiles 2.To Create a Solid Model Use the loft feature

31. Sketch Complexity Complex sketches rebuild faster. Sketch fillets can be recalculated much faster than fillet features, but complex sketches can be harder to create and edit. Simple sketches are more flexible and easier to manage. Individual features can be reordered and suppressed, if necessary.

32. Design Intent Design Intent or can be said “design for change.” Design Intent means that when you put the parametric sketch relations together with the feature intelligence, you can build models that react to change in predictable ways. This gives you a great deal of control over changes. An example of Design Intent could be a written statement that describes general aspects that help define the design of a part, such as: –“This part is symmetrical, with holes that line up with Part A –and thick enough to be flush with Part B.” – From this description, and the surrounding parts, it is possible to re-create the part in such a way that if Part A or Part B changes, the part being described updates to match.

33. Editing or deleting When editing or repairing relations, it is considered best practice to edit rather than delete. Deleting often causes additional problems further down the tree. Many users find it tempting to delete anything that has an error on it.

34. Selecting Display/Delete Relations تمرین 1.کلیه مهره های شطرنج و صفحه آنرا مدل نمایید.
