AutoCAD Based Sprinklers (Ribbon/Toolbar/Location)

Button: Insert Sprinkler Error Type: Bad Argument


When trying to redefine and insert a sprinkler head, you get this message in the command prompt;

Pick head insertion point. Pick any point besides endpoint to break into pipe (try NEArest osnap or TRACKING)
Error: bad argument value: non-negative: -1



The Piping Connection or Sprinkler Specifics values are set to "Other" instead of a real value.  This can be seen when viewing the sprinkler's definition blue box in the ACC1 layer.

For the sprinkler UPRIGHT on the left, the sprig & pipe connection values are set to ½.   This is correct for Imperial.  For sprinkler PEND2, the values are set to 15.  These are correct for Metric but will create an error if used in Imperial.


Verify the values you're entering for the sprinkler head are legitimate.
