The coordinate transformation functions begin with ade_proj.
| ade_projentitybackward | Transforms an entity from the destination coordinate system to the source coordinate system. |
| ade_projentityforward | Transforms an entity from the source coordinate system to the destination coordinate system. |
| ade_projgetctgyname | Identifies the category that a coordinate system belongs to. |
| ade_projgetinfo | Gets information about a projection system. |
| ade_projgetwscode | Gets the project drawing's coordinate system code. |
| ade_projlistctgy | Lists available coordinate system categories. |
| ade_projlistcrdsysts | Lists available coordinate systems in a given category. |
| ade_projptbackward | Computes new coordinates for a source point. |
| ade_projptforward | Computes new coordinates for a destination point. |
| ade_projsetdest | Sets the destination coordinate system. |
| ade_projsetsrc | Sets the source coordinate system. |
| ade_projsetwscode | Sets the project drawing's coordinate system. |
| ade_projwsgeodistance | Measures the geodetic distance between two points. |
