package GccAna 

    ---Purpose : This package provides an implementation of analytics 
    --         algorithms (using only non persistant entities) used 
    --         to create 2d lines or circles with geometric constraints.

uses Standard,
     StdFail,
     gp,
     TColStd,
     TColgp,
     GccInt,
     GccEnt
     

is

    -- Exceptions :

exception NoSolution inherits Failure from Standard;

class Lin2dTanPar;
    ---Purpose : Creates a 2d line TANgent to an 2d entity and PARallel 
    --         to another 2d line.

class Lin2dTanPer;
    ---Purpose : Creates a 2d line TANgent to an 2d entity and PERpendicular
    --         to another 2d entity.

class Lin2dTanObl;
    ---Purpose : Creates a 2d line TANgent to an 2d entity and OBLic 
    --         to another 2d entity.

    --         and a 2d line.

class CircPnt2dBisec;
    ---Purpose : Creates a 2d line BISECting line of a 2d circle 
    --         and a 2d point.

class LinPnt2dBisec;
    ---Purpose : Creates a 2d line BISECting line of a 2d line 
    --         and a 2d point.
