This message typically appears when you are trying to set a value—whether for array spacing, block attributes, viewport scale, or a custom variable—and AutoCAD rejects your input. For new users, this can be confusing. Why 20,000? What integer? And why won’t AutoCAD accept a decimal or a larger number? autocad please enter an integer from 1 to 20000

If you suspect "zombie input" (leftover numbers from typing elsewhere), do this:

1. Press Esc twice.
2. Type the CANCEL command twice.
3. Type (command) at the command line and press Enter. This clears the LISP stack.
