It’s still a backstage question, and there is a question in the backstage, “Can the PPT structure diagram like the one shown below be drawn?” The editor observed that this is actually a simple space-filling model of small molecules. This molecular structure is drawn with chemdraw and then imported. chem3D, it may be more accurate to adjust the display mode. Of course, for our scientific research drawing, it is also possible to use PPT to draw, and it is more concise and beautiful. Here is a corresponding introduction, and strive to provide a more general method. Due to limited time,This part is mainly based on ideas, for reference only, hope it is useful! ! !
Impressions (with and without shadows):< /span>
Text:
1. Oxygen or nitrogen molecular structure drawing: Hold down the "shift" key on the keyboard and drag the "ellipse" (in the basic shape) to draw a perfect circle, select red for "shape fill", and "shape outline "Select "No Outline", the width and height of the circle are both "3.6 cm"; press and hold the keyboard "shift" and "Ctrl" keys and drag horizontally to copy; frame select both or press and hold the keyboard "Ctrl" to add two circles , right click, combine-group together, add top and bottom prisms to the small red circle (prism type "circle"), width and height are directly input "1.8 centimeter" (half of the diameter), and then press Enter, then it will be automatically converted into pounds; given a rotation angle (this Y-axis 270 degrees, press Enter), then the two will be integrated; then adjust the "material" and "light source", and then the three-dimensional rotation is also three-dimensional.
{That is:Give a rotation after the combination and it will be integrated}
2. Promotion 1: Change the color, if it turns blue, it is nitrogen; given three rings (circle, Select "No Fill Color" for "Shape Fill", select a color for "Shape Outline") Give a certain depth in the 3D format, select all together, rotate the angle at will, and then adjust the "Material" " and "light source" to get "Olympic Ring"; hydrogen and carbon dioxide molecules are similar.
Further optimization, add shadows, as follows:
3. Promotion 2:Water (H2O) molecular drawing, Hold down the "shift" key on the keyboard and drag the "ellipse" (in the basic shape) to draw a perfect circle, select red for the "shape fill", and "no outline" for the "shape outline"; similarly, draw two small white-gray circles, Vertically center the two small white and gray circles, align the big circle with the center of the two small circles, and turn all three into three-dimensional balls (ThreeD direct penalty kicks are also acceptable), Right-click to combine the three , rotate the angle, change the material and light source to obtain the water molecule model, and further optimize it by giving shadows, etc. The same is true for H2S.
4. Promotion 3: Methane (CH4) molecule drawing, Hold down the "shift" key on the keyboard and drag the "ellipse" (in the basic shape) to draw a perfect circle, select dark gray for "shape fill", and "shape outline" No outline"; similarly, draw a small light gray circle, and align the two horizontally and vertically; select the small circle in the middle, and select the iSlide plug-in (background reply "iSlide” to get ), find the circular distribution, set the number to 3, and the distribution radius here is 103, close it to draw three circles at the bottom; press and hold the circles and all become balls , combine the four together, in the "3D Rotation", give a 90 degree to the Y axis, and press Enter; in the menu bar, find "Format" - "Selection Pane", click to find the group of these circles , find the small circle in the middle, and find a suitable value for the "height from the bottom edge" under "3D rotation" (You can try it yourself change the size, the small ball moves up and down); similarly, the big ball in the middle can also adjust the space position in this way, and then < /span>Change the lower angle, given the material and light source, the methane is ready, add shadows for further optimization as follows. 
5. Promotion 4: The adjustment method is similar to 4, you can further draw the following picture
