Tutorial by Voibor

Recently I was offered a spiral to an infrared heater, I now present a spiral with a freer construction and with the ability to change the pitch of the helix and to ask any number of rotating spirals.

  1. Step 1:

    Construction of two spiral designs

  2. Step 2:

    Construction of a spiral surface

  3. Step 3:

    Building designs for the second helix

  4. Step 4:

    Construction of a helical surface traektorii

  5. Step 5:

    Construction of three-dimensional sketch along the line of intersection dvoh surfaces, and the construction of the spiral ends with spline

  6. Step 6:

    Hiding surfaces

  7. Step 7:

    Construction of auxiliary surface for eskizaprofilya helix, and the construction of three-dimensional spiral.

  8. Step 8:

    The spiral is constructed ! ! ! ! !
