Sets the maximum zoom level at which the shape is visible.

VEShape.SetMaxZoomLevel(level);

Parameters

Parameter Description

level

An integer specifying the maximum zoom level.

Exceptions

This method throws an exception if level is either greater than 21 or less than the current minimum zoom level.

Remarks

The default maximum zoom level is 21.

If the minimum and maximum zoom levels are equal, the shape is visible only at that zoom level.
