Tutorial - Modeling 3 pipe joint in SolidWorks?

Tutorial by Sudhir Gill
Small

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.
