# Tutorial - Modeling 3 pipe joint in SolidWorks?

Here is the tutorial.

1. ### Step 1:

Start SolidWorks.

2. ### Step 2:

Top plane >> Sketch.

3. ### Step 3:

Draw three equal construction line at 120º.

4. ### Step 4:

Exit the sketch.

5. ### Step 5:

Reference geometry >> Plane. Select the line and the end point. Click OK.

6. ### Step 6:

Similarily create another plane for the line.

7. ### Step 7:

Same step for third.

8. ### Step 8:

Plane1 >> Sketch.

9. ### Step 9:

Draw a circle of 50mm dia.

10. ### Step 10:

Select Extruded surface under surface tab.

11. ### Step 11:

Extrude it towards the Origin with a distance of 100mm.

12. ### Step 12:

Plane2 >> Sketch.

13. ### Step 13:

Draw circle of 50mm diameter.

14. ### Step 14:

Extrude surface it with the same distance and towards the origin.

15. ### Step 15:

Plane3 >> Sketch.

16. ### Step 16:

Draw circle of 50mm diameter.

17. ### Step 17:

Extrude surface it with the same distance and towards the origin.

18. ### Step 18:

Top plane >> Sketch.

19. ### Step 19:

Draw 3 lines collinear to each other and parallel to edge of pipe. These are 3 lines not one. This will create 3 edges.

20. ### Step 20:

Exit the sketch and select trim surface under surfaces tab.

21. ### Step 21:

Trim the surface using the line sketch as trimming tool.

22. ### Step 22:

Similarily trim other two extrusions.

23. ### Step 23:

Select lofted surface tool under surfaces tab.

24. ### Step 24:

Select the edge of the pipe.

25. ### Step 25:

And the corresponding edge of the other pipe.

26. ### Step 26:

Under start/End constraints change them to Tangency to face. Click OK.

27. ### Step 27:

Create the same feature for other two pipes.

28. ### Step 28:

Same step for remaining two edges.

29. ### Step 29:

Select Filled surface tool under surfaces tab.

30. ### Step 30:

Select all upper the edges of the pipes.

31. ### Step 31:

Change contact to tangent.

32. ### Step 32:

Enable Apply to all edges. Click OK.

33. ### Step 33:

Repeat the same step for lower side.

34. ### Step 34:

Knit surface under surfaces tab.

35. ### Step 35:

Select all surfaces and enable merge entities. Click OK.

36. ### Step 36:

Now all surfaces are knitted into one.

37. ### Step 37:

Select Thicken tool under surfaces tab.

38. ### Step 38:

Select the surface knit and thickness be 2mm outside direction. Click OK.

39. ### Step 39:

And the 3-pipe joint is created.
