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 ! ! ! ! !
