1. SolidWorks This is a Powerful and User-friendly software to design 3D model of Mechanical parts and Assemblys,Drawings to manufacture and also FEM analysis, and so on.

2. Starting SolidWorks By click on New, 3 options will be appeared (Part, Assembly, and Drawing)

3. Design a Part Every part is composed of a sketch and a feature 1- Go to Sketch Mode and Draw a 2D sketch(sketch is a drawing that it has no thickness like line, circle, rectangle, arc,… ) 2- Go to Feature Mode, select one of the appropriate commands to create 3D model(such as Cube, Cylinder, spring,…)

4. Creating a Sketch First choose a main plane from Feature manager Tree Select Sketch on the main toolbar 2-Click on Then choose the appropriate geometrical command from Sketch Toolbar Sketch Toolbar Feature Manager Tree Front Plane

5. Feature Manager Tree This box displays all the features of your part or assembly. It also lists planes, axis, and Mating groups. To select the main Planes(Front, Top, and Right) To modify and see the procedure of designing a part, it has a dynamic relation with area of drawing

6. Sketch and Feature Toolbars To create any Sketch (drawing ) use the sketch toolbar. Feature Toolbar: this toolbar contains all the functions for creating and manipulating 3D shapes

7. Basic Feature functions http://www.dmti.unifi.it/dac_prato/modellazione/modelling.html

8. Creating a Part First: Sketch Click on Sketch Click on

9. Creating a Part Choose one of the Main planes to draw the Sketch (Hint:Before creating a sketch you should choose a Plane or a side of part)

10. 2D Sketch After selecting one of the main plane, click on a shape on Sketch Toolbar(Rectangle ) Now, by clicking on the design area and move the pointer you can draw the sketch

11. Adding Dimensions Use Dimension Tool(click on Smart Dimesion) Select the entities to add the dimensions Double click on dimensions to modify the dimensions

12. Dimensions It is not required to add dimension on sketch before use them to create a feature Fully Defiend Sketch: the position of all entities are fully described, and all the entities are BLACK Under Defined Sketch: additional dimensions or relations are needed to completely specify the geometry, under defiened entities are BLUE Over Defiened Sketch, an object has conflicting dimensions or relations, or both. Over defined entities are RED. Over defined Sketch

13. Add relation

14. Feature mode Now by clicking on Features on the main Toolbar, switch to Feature mode Now the feature toolbar will be activated

15. Extrude Extrude the sketch 1-click Extruded base 2-Set End Condition to Blind 3-Set Depth to 10 mm Click OK.

16. Completed Part

17. Extruded Cut Select a side of part as a plane to draw the sketch (by clicking on it)

18. Draw the sketch Click on Sketch Click on Rectangle Draw it on the selected plane

19. Extruded Cut Click on Feature Click on Extruded cut (the preview)

20. Cut-Extrude From the Cut- Extrude Menu Choose the Through All

21. Cut-Extrude

22. Sweep(first create the path) to move a profile along a Path In sketch mode Select Front Plane in Feature manager Draw the path for ex. By clicking spline draw like the picture

23. Sweep(create the x-section) Now draw another sketch as the X-section: Choose the Top plane Draw the profile in sketch mode (cirlce)

25. Reference Geometry Click Insert Choose Reference Geometry 1-Plane Parallel plane Normal to curve plane 2-Axis 3-…

26. Reference geometry a plane parallel to the Front Plane with a distance 10 mm

27. Now a complex example Creating a Spring by Sweep Drawing the circle of spring Curve>Helix Defining the plane Normal to Curve Drawing the circle Sweep

28. Drawing a Helix Curve First Step Draw the sketch of circle in one of the main plane

29. Drawing the Helix Curve Click on Curve command Select Helix Define the Pitch and Revolution

30. Define a perpendicular plane to one end of the helix curve Choose one of the end point of Helix Insert> Ref. Geometry> plane Normal to curve(selec t the curve and an end point)

31. Drawing the x-section In the defined plane, click on sketch Select Circle and draw it (put the center of circle on the end point of curve)

32. Swept Now click on Feature to go to the feature mode then Click on Swept Boss/ Base

33. Sweep In the sweep menu click on the profile box Select the circle as the profile Select the helix curve as the path

34. Edit Sketches and Features From the Feature Manager Tree Right click on each feature select Edit Feature or Edit Sketch

35. Viewing the Part :  You can access the standard engineering views by clicking the Standard Views button on the main toolbar:  Each small box on the "Standard View" menu corresponds to a view of the object. The best way to understand what each view means is to click each view and see what happens.

36. Assembly Open a new assembly file(click on New>Assembly) Insert the created By clicking Mate, make the necessary relation between the parts Save the assembly (with extension.asm or sldasm)

37. Open Assembly

38. Assembly Insert Components Select Existing Part

39. Insert Parts From the box Browse and select the created parts to insert into assembly area

40. Insert the Components(parts)

41. Mate To make the assembly use the appropriate Mate commands, -Coincident -Parallel -Tangent,….

42. Mate (Coincident) Click on Mate Select the First face Use zoom and move or rotate to select the faces

43. Mate(Coincident) Select the Second face Solidworks automatically makes the selected faces coincident

44. Mate(Two components)

45. Mate (Concentric) Click on mate Select the hole and shaft of the Two components Click on Concentric

46. Cardan(Universal) Joint

47. Save as The assembly files should be save as with extention.asm,.sldasm

48. Save(output) To imports the file in different softwares Solidworks provide you to save the files in appropriate format such as Ansys(.igs), Catia, …and Rapid protoype machine(.stl)

49. Save the Assembly in stl format During Save as, click on Options, Choose (save all components of an assembly in a single file)

50. The final file saved in stl format

51. Extracting Dimensions From the Part: Right click where it says annotations on the feature manager design tree, and click where it says 'Show Feature Dimensions':

52. Go to the main file menu and select Tools>Measure Extracting Dimensions From the Part:
