extentLimits Accessor ExtentLimits ViewState Get or set the largest and smallest values allowed for the extents for this ViewState
The default limits vary based on the type of view:
- Spatial view extents cannot exceed the diameter of the earth.
- Drawing view extents cannot exceed twice the longest axis of the drawing model's range.
- Sheet view extents cannot exceed ten times the paper size of the sheet.
Explicitly setting the extent limits overrides the default limits.
