Hi, The following is an extract on adding a blend vertex but I cannot find the path to ADV GEOMETRY. Does anyone know where this is hidden in 2001? To Add a Blend Vertex 1. Choose Adv Geometry from the GEOMETRY menu in Sketcher. 2. Choose Blend Vertex from the ADV GEOMETRY menu. 3. Select the vertex of an existing geometry entity. A circle will be placed there. More than one blend vertex can be created at the same point. Each additional vertex will create a concentric circle of increasing diameter. Thanks
