You received an Invalid input error message when:
- Placing a multileader (MLeader) such as a Spot Elevation callout, plant label, Reference Note callout, etc., OR
- Placing or otherwise working with a groundcover
MLeaders require a series of automated steps. The Invalid input message in the Command line is simply the result of one of these steps.
If you received the message when working with groundcovers, one of your planting areas may be assigned a Stipple hatch pattern. The Stipple pattern can cause this error – especially when used in narrow areas or in any areas that are not simple shapes.
If you saw the error when placing a Spot Elevation callout, plant label, RefNote callout, or other MLeader, you can ignore this message. As long as your callouts are placing correctly, it won't be an issue.
If you received this error when working with groundcovers or Shrub Areas, check whether any of these plants is assigned the Stipple pattern. If you find planting areas that are in fact assigned the Stipple pattern – especially areas that include narrow areas or have irregular shapes – edit the plant and select a pattern besides Stipple.
