@subsubsection occt_algorithms_7_3_1 Case 1: Three edges intersecting at a point
* The Projection Algorithm is used at the Intersection step. The purpose of Projection Algorithm is to compute 2D curves on surfaces. Wrong results here lead to incorrect or missing faces in the final GFA result.
* The Classification Algorithm is used at the Building step. The bugs in the Classification Algorithm lead to errors in selecting shape parts (edges, faces, solids) and ultimately to a wrong final GFA result.
-The description below illustrates some known GFA limitations. It does not enumerate exhaustively all problems that can arise in practice. Please, address cases of Algorithm failure to the OCCT Maintenance Service.

+Pay attention to the Zoom value of the Figures.
It is obvious that starting with some value of *ScF*, e.g. *ScF>1000000*, all sloped p-Curves on *Face 2* will be almost vertical. At least, there will be no difference between the values of angles computed by standard C Run-Time Library functions, such as *double acos(double x)*. The loss of accuracy in computation of angles can cause failure of some BP sub-algorithms, such as building faces from a set of edges or building solids from a set of faces.
- Fuzzy tolerance of the operation is given to the Unifier as the linear tolerance.
- Non destructive mode here controls the safe input mode in Unifier.
-For controlling this possibility in DRAW the command **bsimplify** has been implemented. Please see the @ref occt_draw_bop_options "Boolean Operations options" chapter in draw user guide.
