3D CAD example tutorial: Using the 3D sweep function to draw shaped springs

Common springs are cylindrical (see Figure 1), and 3D CAD designers can easily create renderings using 3D software. And some shaped springs (as shown in Figure 2/3), in fact, as long as the use of the sweep function, it can be easily achieved.
Let's take a look at how the 3D CAD software in China can quickly realize the creation of shaped springs:
Step 1. Use the sketch function to create two sketches for the sweep path and the outline separately. The sweep path sketch, shape and size are specified according to the actual size requirements.
Figure / sweep path sketch
Figure / red line segment is the contour sketch Step 2. After the sketch is created, use the sweep function to sweep out the contoured spiral.
a. Select two sketches respectively, the contour option to select the contour sketch, and the path option to select the path sketch.
b. In the conversion settings, design the distortion option, select the linear, the change value is set as shown below, the input value is the total degree, divided by 360 is the number of spiral turns.
c. Switch to the zoom option in the conversion setting item, the zoom type selection is variable, add points to select several online points on the path and input the corresponding scale to adjust the size of the spiral. The scale is based on the outline sketch. Proportional adjustment.
After the above steps are completed, the effect is as follows:
Step 3. Extract the spiral using the function of the wireframe module.
Step 4. Use the rod sweep function to quickly generate the spring.
Through the above method, the 3D CAD designer can quickly design the effect diagram of the shaped spring. More shaped, more varied shaped springs can be made. Zhongwang 3D's sweeping function is very powerful, and with the parameterized settings, you can draw many special spiral entities.

We provide organic and inorganic pigments to our customers in Middle East, South East Asia etc,you also can find barium sulphate, carboxyl methyl cellulose , melamine and other relative producets here.

Iron oxide red is widely used as inexpensive, durable pigments in paints, coatings and colored concretes.

1. barium sulphate, it is super-fine powder made from high quality barite which is after thoroughly grinding process. The end products have good dispersibility, high whiteness, nice covering power, stable chemical properties.
Application : used in pharmaceutical industry, leather industry, printing and dyeing industry

2. Melamine:
Main Application, Storage and Transportation:
1). Food grade melamine raw material can be used to produce melamine table ware.
2). Also used as industrial grade additive, widely used in plastics, paint textile, paper.
3). Used as the material to produce melamine formaldehyde (MF) colophony.
4). Owning the abilities of fire-resistant, water-resistant, hot-resistant, age-preventing, electric arc resistant, bearing chemical corruption, perfect insulation capability, gloss grade, and machinery intention, and good thermal-setting capacity, it is widely used in wood, plastic, dope, paper-making, textile industry, leather, electric, and medicine, etc.
5) The product is a kind of weak alkaline and nontoxic material. It should be kept in a clean and dry place. Moisture and rain proof with careful handle during storage and transportation.
