Use solidworks to draw the following picture (a snake spring).

Personally, I think it is better to use the wrapping command like this. The steps are as follows:

1, look forward to the datum plane and draw a sketch. First, draw a cycle unit, define the size, for example, the width of each unit is L= 10, make a whole column of N= 10 with the sketch array, and then add a straight line to close the sketch and confirm the exit;

2. Draw a circle from the datum plane, mark the diameter d of the circle, add an equation (when modifying the size, the input box has an inverted triangle, click it, and "Link Value" and "Add Equation" will appear. Select Add Equation, enter "100/pi", and the value of 100 is the value of N*L), and confirm to exit.

3. Stretch the surface tool to stretch the circle in step 2, but the height direction of the sketch in step 1 must be included at the upper and lower ends of the surface;

4. Cladding command: the surface of cladding sketch is drawn, and the sketch is the sketch of step 1, and a line is drawn on the surface;

5. Draw a three-dimensional sketch and convert it into a solid reference command, convert the circular curve into a three-dimensional sketch surface, and confirm to quit the sketch;

6. After using the scan command, the scanning path required for the 3D sketch is not clear here.
