To rotate the numbers in CAD by 90 degrees, you can use the built-in rotation command in CAD software or the rotation function in 3D modeling software.The specific steps are as follows: 1. In CAD software, find the number to rotate and select it. 2. Find the "Rotate" command on the menu bar or toolbar and click Open. 3. In the pop-up dialog box, select "90 degrees" or other user-defined angle options, and set as required. 4. Click the "OK" button to complete the rotation operation. If you need to adjust the rotation angle more finely, you can consider using 3D modeling software.In the 3D modeling software, select the number to be rotated and open the editing mode. 5. In edit mode, find and open the "Rotate" function on the "Edit" menu or toolbar. 6. In the pop-up dialog box, select "90 degrees" or other custom angle options, and set as required. 7. Click the "OK" button to complete the rotation operation. Through the above methods, the numbers in CAD can be easily rotated by 90 degrees.
