Summary0025601: General Fuse fails on a Face and a Vertex on it.
DescriptionThe result is a compound of a Face and a vertex and the face and the vertex have no relation to each other. The expected result should be a face containing the vertex. Also the box and the cone boolean fuse have the same issue.
TagsNo tags attached.

The summary may not express the issue correctly. The problem is not "failure", but the result is incorrect. The result should consider non-manifold case and add the vertex to the face as sub-shape.

I have double checked the generated file box_cone_fuse.brep, the vertex is already correctly added to the face. But the single face and single vertex general fuse have this issue.

0025587 indicates that the cone apex in the box top face is missing parametric infomation PointOnSurface.

BRep_Tool::Parameters (const TopoDS_Vertex& V, const TopoDS_Face& F) throw Standard_NoSuchObject for face internal point.
