How to make curved surface cut in modeling bottle ?

Tutorial by Frederik Vollbrecht
Small

For round bottle:

  1. Step 1:

    Create or open the main body.

  2. Step 2:

    Add a sketch to right or front plane.

  3. Step 3:

    Draw a rectangle. It must be vertical to the axis of rotation.
    To produce the same wavy lines on the base body, the rectangle must be constructed according to the equation e=√2 * l, where e is the corner dimension of an imaginary square and our diameter.

    Solved to l---> l=d/ √2.
    In my case l= 60mm/√2 = 42,43mm

  4. Step 4:

    Add the wavelines

  5. Step 5:

    Now you have to use the "project sketch" method.
    Just select the wave-sketch and the face of the rotation

  6. Step 6:

    If u done it right, you have to add a plane on the end/ startpoint of the projected line and the line itself

  7. Step 7:

    Create your cutting-geometrie. remember to plug the geometrie on the projected line and the outer edge.

  8. Step 8:

    Cut the geometrie along the projected line.
    At this point it should look like this.

  9. Step 9:

    Since the cut only goes through a quarter of the surface, it must be arranged rotationally.

  10. Step 10:

    Done ;)
