Tutorial: How to make Dodechahedron


Here is another method to make the same without using any angles :-)
Inspired from the model How to model a Dodecahedron from scratch by Steen Winther.
Here is the model:
Request: Dodechahedron
Hope this will be helpful to many..

  1. Step 1:

    First, make a simple pentagon and make a planer surface from it.

  2. Step 2:

    Save the file with any name, Say "Surface".

  3. Step 3:

    Now Make an Assembly and import that part "surface".

  4. Step 4:

    Insert another same surface and make co-incident relations(mates) of
    1. edge-to-edge
    2. Point-to-Point.
    As shown in the picture.

  5. Step 5:

    Insert 3rd surface and again make relations(mates) like the previous one.
    but with another edge of the base surface as shown in the picture.

  6. Step 6:

    Now make an edge-to-edge mate with one edge of the second part and second edge of the third part as shown in the pictures.

  7. Step 7:

    Add another part and make two edge-to-edge mates as shown in the picture.

  8. Step 8:

    Then insert more surfaces and add all the required mates,
    i have shown the last mate required in the assembly.

  9. Step 9:

    Click "Save as".

  10. Step 10:

    Select "Part" as type to save the file with any name say "Final".

  11. Step 11:

    Remember to check "exterior Faces" in "Geometry to save".

  12. Step 12:

    Now open the saved part file and knit all the surfaces to make the part a solid.
    Remember to Check "Try to make solid" under selections.

  13. Step 13:

    Additionally we can add fillets to the model.
    Best way to add fillets is to use FilletExpert.

  14. Step 14:

    Here is a cascade view of all the files.(Surface, Assembly and Final).
