## Detailed Description

The GeomAPI package provides an Application Programming Interface for the Geometry.

The API is a set of classes and methods aiming to provide :

- High level and simple calls for the most common operations.
- Keeping an access on the low-level implementation of high-level calls.

The API provides classes to call the algorithmes of the Geometry

- The constructors of the classes provides the different constructions methods.
- The class keeps as fields the different tools used by the algorithmes
- The class provides a casting method to get automatically the result with a function-like call.

For example to evaluate the distance <D> between a point

and a curve `, one can writes :`

`D = GeomAPI_ProjectPointOnCurve(P,C);`

`or`

`GeomAPI_ProjectPointOnCurve PonC(P,C); D = PonC.LowerDistance();`

This function builds (in the parametric space of the plane P) a 2D curve equivalent to the 3D curve C. The 3D curve C is considered to be located in the plane P. Warning The 3D curve C must be of one of the following types:

- a line
- a circle
- an ellipse
- a hyperbola
- a parabola
- a Bezier curve
- a BSpline curve Exceptions Standard_NoSuchObject if C is not a defined type curve.

Builds a 3D curve equivalent to the 2D curve C described in the parametric space defined by the local coordinate system of plane P. The resulting 3D curve is of the same nature as that of the curve C.
