Custom programming routines that generate geometry mathematically can fail if a calculation outputs a value lower than 1 or higher than 20,000. Step-by-Step Solutions to Resolve the Prompt 1. Adjust the HPMAXLINES System Variable

(VIEWRES) variable being corrupted or set incorrectly by a third-party application. Autodesk Community, Autodesk Forums, Autodesk Forum Immediate Fix dialog box (type in the command line). Navigate to the Locate the Display resolution Change the value for Arc and circle smoothness

: Run an AUDIT and PURGE on any drawing received from an outside source before copy-pasting elements into your main project.

Drawing corruption can cause system variables to misread geometry scales.

: Open a new, empty template ( acad.dwt or acadiso.dwt ) and use the INSERT command to bring the problematic drawing's geometry into the clean file.

AutoCAD, however, is the sanctuary of the integer. It is the temple of the absolute. When you enter a number here, it is not an approximation. It is a law. If you type 1 , the software does not interpret it as "roughly one" or "one-ish." It interprets it as the precise coordinate of 1.0000000000.

Type AUDIT and press . Type Y for Yes to fix any detected errors.

: This message is the specific prompt for the VIEWRES command, which controls the "circle zoom percent" (the smoothness of curved lines).

❌ Zero items makes no sense in commands like Array or Divide. If you want no change, cancel the command.
