The following methods allow the application programmer or customiser to query the geometry of items.
| GetClosestPt |
Gets the closest point on any linear geometry of the current open Item to the given position. |
| GetClosestVertex |
Gets the closest vertex of the current open Item to the given position. |
| GetExtent |
Gets the extents of the current open item. |
| GetGeomAngleFromLength |
Gets the tangent angle a specified length along geometry from the current open item. |
| GetGeomDim |
Gets dimension of geometry from the current open item. |
| GetGeomIntersections |
Looks for intersections between a single piece of geometry from the current open item, and items in the given Named List. |
| GetGeomLength |
Gets length of geometry from the current open item. |
| GetGeomLengthUpto |
Gets the length along the current open item's geometry up to a position. |
| GetGeomNumPt |
Gets the number of vertices in geometry from the current open item. |
| GetGeomNumSeg |
Gets the number of segments in geometry from the current open item. |
| GetGeomPosFromLength |
Gets the position a specified length along geometry from the current open item. |
| GetGeomPt |
Gets the position of a vertex from geometry in the current open item. |
| GetGeomSegAxis |
