CAD tip # 11415:

Question CAD

Error in pattern file. Missing parameter on line XXX.

When trying to add a hatch with a selected custom hatch pattern, AutoCAD or AutoCAD LT displays the error "Error in pattern file." or "Bad pattern definition file: Missing parameter on line NNN.", resp. "Error in pattern file."

The most common primary cause is a missing end-of-line character (Enter) on the last text line in the .PAT file. Make sure the last line is an empty line - e.g. pressing Ctrl+End in Notepad should move your cursor below the last line of the pattern definition.

A .PAT file must by a standard text file, not a file edited e.g. in MS Word. Also remember that custom .PAT files should contain only a single hatch pattern definition. The individual lines of the definition may contain max. 80 characters.
