3D circular twist modeling in CAD common modeling

Many CAD designers involve modeling in the design process, and using an efficient and simple CAD/CAM software often allows them to improve efficiency and get twice the result with half the effort. As a cost-effective CAD/CAM software, Zhongwang 3D is a good choice for them. Figure 1 is a rendering of a circular twisted product using Zhongwang 3D modeling. The modeling process is very simple. The specific steps are as follows:

Figure 1

1. Use the sketch function , select the XY plane to draw sketch A and sketch B respectively:

Figure II

2. Create a circular helicoid using the standard sweep function:

Figure III

Note: The numerical meaning of the digital input box in the above figure is 1800 degrees in the forward and reverse directions, a total of 3600 degrees, that is, 10 circles around the circle.
