Specific steps:

1. Open CAD20 16 and enter the CAD operation interface:

/iknow-pic . cdn . BCE Bos . com/48540923 DD 54564 e0b 5 12 ddbdde 9 c 82d 1584 f 1 a " target = " _ blank " title = " " class = " ikqb _ img _ alink " >/iknow-pic . cdn . BCE Bos . com/48540923 DD 54564 e0b 5 12 ddbdde 9 c 82d 1584 f 1a？ x-BCE-process = image % 2f resize % 2Cm _ lfit % 2Cw _ 600% 2Ch _ 800% 2c limit _ 1% 2f quality % 2Cq _ 85% 2f format % 2Cf _ auto " esrc = "/ 48540923 DD 54564 e0b 5 12 ddbdde 9 c 82d 1584 f 1a "/>

2. Find the option to switch workspaces in this interface;

/iknow-pic . cdn . BCE Bos . com/d53f 8794 a 4c 27d 1e 1a 33 f 220 1 5 D5 ad 6 eddc 43839 " target = " _ blank " title = " " class = " ikqb _ img _ alink " >/iknow-pic . cdn . BCE Bos . com/d53f 8794 a 4c 27d 1e 1a 33 f 220 15d 5 ad 6 eddc 43839？ x-BCE-process = image % 2f resize % 2Cm _ lfit % 2Cw _ 600% 2Ch _ 800% 2c limit _ 1% 2f quality % 2Cq _ 85% 2f format % 2Cf _ auto " esrc = "/ d53f 8794 a 4c 27d 1e 1a 33 f 220 15 D5 ad 6 eddc 43839 "/>

3. Click the Switch Workspace option and find the 3D modeling option in the submenu:

/iknow-pic.cdn.bcebos.com/96DDA144ad345982d68a2c7602f431adcaef84d6 "target =" _ blank "title =" "class =" ikqb _ img _ alink ". /iknow-pic . cdn . BCE Bos . com/96 DDA 144 ad 345982d 68 a2 c 7602 f 43 1 ad caef 84d 6？ x-BCE-process = image % 2f resize % 2Cm _ lfit % 2Cw _ 600% 2Ch _ 800% 2c limit _ 1% 2f quality % 2Cq _ 85% 2f format % 2Cf _ auto " esrc = "/ 96 DDA 144 ad 345982d 68 a2 c 7602 f 43 1 ad caef 84d 6 "/>

4. Click the 3D modeling option, and you can see that you have entered the 3D modeling mode:

/iknow-pic.cdn.bcebos.com/29381f30e924b899ba4b7dc60061d950b7bf65e "target =" _ blank "title =" "class =" ikqb _ img _ alink. /iknow-pic . cdn . BCE Bos . com/2938 1 f 30 e 924 b 899 BAC 4 b 7 DC 6006 1d 950 b 7 BF 65 e？ x-BCE-process = image % 2f resize % 2cm _ lfit % 2Cw _ 600% 2Ch _ 800% 2c limit _ 1% 2f quality % 2Cq _ 85% 2f format % 2Cf _ auto " esrc = "/ 2938 1 f 30 e 924 b 899 BAC 4 b 7 DC 6006 1d 950 b 7 BF 65 e "/>；

5. Find the box option in the menu area:

/iknow-pic.cdn.bcebos.com/09fa513d269759ee1453a92ffbcfb43166c22dfd7 "target =" _ blank "title =" "class =" ikqb. /iknow-pic . cdn . BCE Bos . com/09 fa 5 13d 269759 ee 1453 a 92 FB CFB 43 166 c 22 DFD 7？ x-BCE-process = image % 2f resize % 2Cm _ lfit % 2Cw _ 600% 2Ch _ 800% 2c limit _ 1% 2f quality % 2Cq _ 85% 2f format % 2Cf _ auto " esrc = "/ 09fa 5 13d 269759 ee 1453 a92 FB CFB 43 166 c 22 DFD 7 "/>

6. Click the box option, and you can see that there are many 3D objects in the drop-down list:

/iknow-pic.cdn.bcebos.com/91529822720e0cf3e1e0871f0446f21fbe09a3b "target =" _ blank "title = /iknow-pic . cdn . BCE Bos . com/9 1529822720 E0 cf 3 e 1e 087 1f 0446 f 2 1 FBE 09 aa 3b？ x-BCE-process = image % 2f resize % 2Cm _ lfit % 2Cw _ 600% 2Ch _ 800% 2c limit _ 1% 2f quality % 2Cq _ 85% 2f format % 2Cf _ auto " esrc = "/ 9 1529822720 E0 cf 3c F3 e 1e 087 1f 0446 f 2 1 FBE 09 aa 3b "/>

7, select the pyramid, create a pyramid in the drawing area, and then select the southeast isometric option in the three-dimensional navigation:

/iknow-pic . cdn . BCE Bos . com/3b 87 e 950352 AC 65 c 4633 af 97 f 5 F2 b 2 1 193 1 38 a 24 " target = " _ blank " title = " " class = " ikqb _ img _ alink " >/iknow-pic . cdn .

8. Select the color option in the visual style:

/iknow-pic . cdn . BCE Bos . com/e 1 Fe 9925 BC 3 15 c 60 a 66 ea 50 b 83 b 1cb 1 34854775 f " target = " _ blank " title = " " class = " ikqb _ img _ alink " >/iknow-pic . cdn . BCE Bos . com/e 1 Fe 9925 BC 3 15 c 60 a 66 ea 50 b 83b 1cb 134854775 f？ x-BCE-process = image % 2f resize % 2Cm _ lfit % 2Cw _ 600% 2Ch _ 800% 2c limit _ 1% 2f quality % 2Cq _ 85% 2f format % 2Cf _ auto " esrc = "/ e 1 Fe 9925 BC 3 15 c 60 a 66 ea 50 b 83b 1cb 134854775 f "/& amp

9. After setting, you can see the created 3D object:

/ik now-pic . cdn . BCE Bos . com/b 2 de 9 c 82d 158 ccbf 39 a 7 CDE 17d 8 BC 3 EB 1354 134 " target = " _ blank " title = " " class = " ikqb _ img _ alink " >； /iknow-pic . cdn .
