GetGeomDim Method
Description
Gets the dimension of the geometry from the current open Item.
Syntax
Visual Basic |
---|
Public Function GetGeomDim( _ ByVal nGeom As Long _ ) As Long |
Parameters
- nGeom
- The index of the geometry component, starting at 0.
Return Type
The dimension of the geometry component. For example, a Polygon item is 2-dimensional, a LineString item is 1-dimensional, a Point item is 0-dimensional, etc.
Remarks
Use GetNumGeom to get the number of geometry components in an Item.
Items such as blocks, groups, MultiLineStrings, and so on, can be made up of multiple geometry. Therefore the value of nGeomcan be greater than 0. Items such as LineString items, polygons, symbols, and so on, are made by a single piece of geometry. Therefore the value would be 0.
