Issue:

Enter the command OPTIONS and press Enter, when entering OPTIONS, the prompt "Arc and circle smoothness: Please enter an integer from 1 to 20000." pops up, and I cannot click on any other pages or items, what should I do?

Causes:

The setting value of "Arc and circle smoothness" in this drawing exceeds the allowable range of 1~20000, so this prompt will pop up immediately while entering OPTIONS.

Solution:

  1. Enter the command VIEWRES, press Enter, and set its value to 1000
  2. Then enter OPTIONS, the prompt will not pop up
